Mothership Terminal

A station-computer terminal for the Mothership RPG. Players type into a CRT screen and an AI model (DeepSeek or Claude) answers as the station, in any number of voices. The Warden (game master) steers it from a separate console.

Play it at shawnofthe.dev/mothership, or run your own copy.

How a game works

1. The Warden opens /dm, picks a provider and pastes their own API key (or picks Free (shared) if the server offers it), and clicks Create session. They get a six-character session code.
2. Players open / (the terminal) on a laptop or TV, enter the code, pick their crew file (character), and start typing.
3. Many sessions can run at once; each is separate.

API keys:

• Each Warden brings their own key and pays their provider for what the agent uses. DeepSeek Flash costs a fraction of a cent per reply.
• Keys are held in the server's memory only. They are never written to disk or sent to players.
• After a server restart the Warden re-enters the key, or ticks Remember this key on this device to have their browser re-send it. A reply cut off by a restart is not lost: lines that were still being scheduled show again, and an unanswered player line gets a Warden note to press Generate.
• No key? If the server sets OPENROUTER_API_KEY, the start screen offers Free (shared): OpenRouter's free models, on the server's key. OpenRouter rate-limits free models per key, so every session shares one allowance, and each session gets FREE_CALLS_PER_DAY replies a day (default 150). The free provider never takes a Warden's key, and the server's key is only ever used for free models. A Warden can add their own key under 🔑 Key at any time and switch.

Getting back into your console:

• The console is tied to the device that created the session.
• Copy Warden link opens it on another device.
• Idle sessions are deleted after two weeks.

Playing without a Warden

A group can play with no Warden at all: the AI builds a story and runs it.

1. On the player page (/), NO WARDEN? START A GAME YOURSELF opens a short setup: pick the AI (the free shared model needs no key; DeepSeek or Claude use your own key) and start. Whoever does this is the pilot.

2. Everyone picks a story together. The terminal lists KESTREL-9 (ready at once) and four new sci-fi horror pitches the AI comes up with; the pilot picks one (or asks for other stories). Share the session code or link (under PILOT) and others join as usual; they see the same list.

3. The AI builds it (a minute or two, longer on the free model; the same builder as Story Builder): station, lore, secrets, cast, map, terminals and four characters. Everyone picks a crew file, and the AI opens the scene.

4. Then it plays like a normal game. Player screens say THE AI ANSWERS where a game with a Warden says THE WARDEN ANSWERS. The AI is the Warden too: uncertain attempts become rolls for whoever tried them, with the stakes on the roll prompt (IF IT WORKS / IF IT FAILS); when no roll fits, it rules fairly itself. It calls Panic checks when something truly horrifying happens, applies harm and Stress, and characters nobody is playing roll by themselves.

5. It ends. When the story reaches its end (an escape, everyone dead, a terrible truth), the AI plays the final scene and every screen shows THE END: how it ended, and a recap it writes (what happened, the truth now that it's over, each character's fate). The pilot can also Wrap up the story any time, or Play another story.

A campaign with no Warden. The story list also offers RIM HAULERS (campaign) next to KESTREL-9. Picking it starts the campaign (see Campaigns below) and the terminal shows THE JOB BOARD: the stories not yet played at the port where the rig is, and on the lanes that leave it (from Port Gallow: FIRST SHIFT, QUARANTINE, COLD CHAIN and LIVESTOCK), with only what the players may know (title, hook, the job, where, the lane's length), never the arc, adversary, secrets or cast. The pilot picks one; it is built like a Warden-run campaign story (the crew's sheets, the rig's fuel and stores, faction standings and the recurring characters carried in). When the AI ends it, or the pilot wraps it up, the campaign records it with the recap's verdict as its outcome. Faction standing (a house rule) moves only for the faction stakes the AI judges clearly earned from the log, conservatively. The rig is then where the story left it, and Play another story returns to the job board from there. Downtime runs by itself (PSG 20.2): each living character rolls a Body Save (success: Health back to Maximum, Wounds stay) and a Rest Save on their worst Save (success: Stress down by the ones digit of the roll, never below Minimum Stress; failure: +1 Stress; [-] with the Nightmares Condition; none in cryosleep). A Critical Failure on either Save also gets a Panic Check, rolled by the dice for that character, and Stress over 20 reduces the Save just rolled (PSG 20.1; "the most relevant Stat or Save" read as the Save rolled), all logged and shown on the END screen. Leave the campaign on the board goes back to the story list. The board also lists TRAVEL (every lane from the port: destination, days and fuel cost, 1 fuel per started 3 days, a house rule) and REFUEL (buys fuel from the rig account at the 500cr-a-unit default, times the port's multiplier: a house rule; it fills the tank, or as much as the account affords). A rig that can't afford the cheapest lane and can't buy the fuel for it gets CALL DISPATCH (house rule): Local 1312 advances the fuel for that lane, its price is added to the note as a "Union fuel advance", and Union standing is unchanged. TRAVEL, REFUEL and CALL DISPATCH each ask first, quoting the days, fuel, units or credits involved (and the fuel left, or the note before and after), and afterwards a result line appears on the board and in the log (for example TRAVELLED TO TOLLGATE: 3 DAYS, 1 FUEL. 9 LEFT.); the board also shows the rig account and the Gallow-Mercer note. When the AI finishes building a story, every screen without a character opens the crew picker with NEW STORY: TITLE. CHOOSE YOUR CREW FILE. If the recap fails, the job is paid as delivered in full and the log says so. When the fuel is below the cheapest lane, the board warns; a job or a lane the rig can't afford is refused with NOT ENOUGH FUEL. Lane jobs run one way, from their start port to their destination. Players keep their character from one job to the next (only a dead or retired character's seat is cleared), in Warden-run campaigns too. (see High Score and the memorial): finishing a story rests the crew and pays the rig, but only a Warden's End game night adds to High Score or to the campaign's sessions played.

The free model works but is slow (a reply can take a minute) and writes thinner stories; the setup says so and suggests DeepSeek. Players see how long the AI has been thinking (PROCESSING · 23S).

PILOT (only on the pilot's screen; the session token is kept on that device) has the invite code and link, the AI provider, model, thinking and key, Choose a new story and End the game. The pilot never sees the Warden's console, so there are no spoilers for them either. If the AI fails to answer, every screen gets a short notice and the players can just type again.

Run it yourself

1. Install dependencies:

   npm install
   

2. Start the server:

   npm start
   

3. Open http://localhost:3000/dm to start a session. Players join at http://<your-ip>:3000/.

Optional settings go in .env (see .env.example): BASE_PATH to serve under a sub-path, DATA_DIR, session limits.

On your own computer, any key in .env (DEEPSEEK_API_KEY, ANTHROPIC_API_KEY) is used automatically: the start screens (Warden and no-Warden) offer that provider as "this computer's key" with nothing to paste, and the session keeps using it after a restart. That only happens when the server isn't in production (the live server runs with NODE_ENV=production) and the page is opened on this computer at localhost, not through a proxy; anyone else still brings their own key.

For a private LAN game you can set ALLOW_SERVER_KEYS=1 plus DEEPSEEK_API_KEY / ANTHROPIC_API_KEY, so sessions use the server's keys. Never do that on a public server.

On a hosted server, setting ANTHROPIC_API_KEY and CLAUDE_KEY_PASSWORD lets anyone who types that password where a Claude key goes (the start screens or the key dialog) run their session on the server's Claude key. It works in production without ALLOW_SERVER_KEYS, only for Claude, and is light protection only (10 wrong tries per address per 10 minutes): share the password only with people you trust with the bill.

If a session has no key, the agent stays quiet and you reply yourself with Speak.

To host it publicly, see deploy/README.md. The hosted copy at shawnofthe.dev/mothership deploys automatically on every push to main.

Telemetry and keys

The server counts how it's used (page views, sessions, connections, player messages, LLM calls and how long they take, rolls, which Warden tools get used) and sends the counts to a CloudWatch agent on the same machine, if there is one (telemetry.js). The hosted copy's numbers are on a CloudWatch dashboard (see deploy/README.md). Running it yourself, nothing is sent anywhere; set TELEMETRY=0 to turn it off completely.

LLM keys are never logged or recorded. Telemetry can only hold fixed values (a provider or model name, a number, one of a few known words), never text: no keys, session codes, names, IPs or anything anyone typed, and any record that looked like it held a key would be dropped. Every line the server prints goes through redact.js too, which blanks out the keys sessions hold and anything shaped like a key.

Choosing the AI

The picker in the console's top bar sets the provider, model and thinking effort. You can change them at any time, even mid-session. 🔑 Key adds or replaces the session's key for any provider. Every list is ordered cheapest-first, and a session starts on the cheapest model it has a key for.

Provider	Models (cheapest first)	Notes
DeepSeek	deepseek-flash, deepseek-v4-pro	Cheapest option. Default effort is "thinking off" (fastest). Uses JSON mode; replies are checked and cleaned up on the server.
Free (shared)	openrouter/free, nvidia/nemotron-3-super-120b-a12b:free, google/gemma-4-31b-it:free	Only when the server sets OPENROUTER_API_KEY. Costs nothing; slower and less sharp, and shares OpenRouter's free rate limit. openrouter/free picks whichever free model is up. The free lineup changes often, so update providers/free.js when one disappears.
Claude	claude-haiku-5-5 (the cheapest: $0.10 / $0.50 per MTok), claude-haiku-4-5, claude-sonnet-5-5, claude-opus-5-5	Uses structured outputs, so replies match the schema; a schema too large for strict output (the game reply is) goes as JSON text with the schema in the prompt instead, as for DeepSeek. Sonnet and Opus fall back to another model automatically if they decline a request.

Adding a provider

Providers live in providers/. Each one is a module exposing { id, label, envKey, keyHint, keyUrl, models, generate({ apiKey, ... }) }.

For anything that speaks the OpenAI chat-completions format (OpenRouter, Groq, Together, a local Ollama or LM Studio), copy providers/deepseek.js. Change the baseURL, key details and model list, then add it to PROVIDERS in providers/index.js. The console picks it up automatically.

Testing

• npm test: the unit tests. Fully offline and guarded (test/setup.mjs removes the API keys and refuses any request that is not to this machine), so it never spends tokens.
• npm run dev:mock: the app (port 3000, or PORT) on a mock model (scripts/mock-llm.mjs, port 3011) instead of DeepSeek, with its data in ./.tmp-mock. Every reply is a canned MOCK: the station hums. and the Story Builder, pitches, synopsis and so on get minimal valid answers. For trying the app out, no tokens. npm run mock-llm runs just the mock; set DEEPSEEK_BASE_URL to point any server at it.
• npm run test:integ: the live regression suite against DeepSeek (test/integ/regress.mjs; npm run test:integ:eval for eval-steering.mjs). It costs tokens, so run it only on purpose: it needs DEEPSEEK_API_KEY and refuses without --live (the script adds it) or INTEG=1. Options go after --, e.g. npm run test:integ -- --runs=1 --only=secret-guarded. node test/integ/regress.mjs --dry builds every scenario's request without calling anything.

The default story: KESTREL-9

A rimward ice-mining platform where the drill team broke into a "pressurised void" 19 days ago. The players are a convict maintenance crew sent by Hollis-Vane on the prison tug SECOND CHANCE to service the station's reactor. Everything went wrong while they were in transit, so nobody briefed them and they brought tools, not weapons. They start aboard their tug, at the SECOND CHANCE's own terminal, just docked at Airlock A. Through the docking collar the airlock's inner door is sealed: opening it (their work order has the override code) is the first thing they do, and the rest of the station opens up from there.

Getting home: the SECOND CHANCE is built not to undock until the station approves the job. HV-CORE has to verify the reactor running at 99% efficiency or better. It is at 70%, and HV-CORE shows an energy drain in the Deck 3 cargo bay, which is where the thing from the void is. The station state tracks it (power.efficiency_pct, power.drain, second_chance.departure_clearance), and the tug's own terminal (cyan, aboard the tug; the station's screens are green) waits for the clearance code.

• Player characters (all legal 1e characters: class ranges, Max Wounds and skill prerequisites are checked by a test): Teodora "Rook" Rusk (Teamster rigger, hijacked a hauler to save her brother's kids), Elias "Tick" Varga (Scientist, cooked combat stims), MOLL-7 (Android, refused an order that would have killed two workers) and Dax Oyelaran (ex-Marine, struck an officer to hold an evac ramp). Each has full Mothership stats, saves, health, skills, loadout, trinket and patch.
• Cast on the intercom, each with a description and their own voice: Administrator Ruth Okonkwo, Dr. Imre Salk, Chief Engineer Hana Marlowe, Security Officer Dmitri Voss, Comms Officer Juno Adar, drill lead Anton Petrov, drillers Carys Webb and Pell Ostrand, and refinery hand Sam Yusuf.

Synopsis

Synopsis (top of the console) has the agent write one of three, picked at the top of the dialog. It opens on the prebrief before play and on the story so far once play has started.

• Prebrief: a short, bulleted briefing to share with the players before play: who they are, where they are, what they know, their job, and their next goals. It's always the setup, as the story started, even if you rewrite it later.
• Story so far: the same, written from the comms so far: what has happened, where they are now, what they know and what they could do next. It tells the players only what their characters have actually learned.
• Wrap-up: for after the one-shot: What happened, a short blurb of the story as it played out (secrets and all, since it's over), and Afterwards, what became of each of the crew in the months and years after, grounded in how they left the story.

The prebrief and the story so far have sections marked For the Warden only: what is really going on (once play is under way, which beats have landed and where everyone is now) and next obstacles to throw at the players, each with how it shows up and ways through. Copy for players copies just the player sections (the whole wrap-up). Each is kept with the session; when the log has moved on since one was written, Update to now rewrites it. Restart story keeps the prebrief and clears the other two. They use the session's model and key.

Player characters

Up to four crew files per session. Every skill carries its bonus, from its tier in the Mothership 1e skill tree (Trained +10, Expert +15, Master +20); edit them on the Crew tab as Zero-G +10, Hacking +15 (a skill the book doesn't have counts as +10 unless you give it one). When a player joins, their screen asks which one is theirs (press its number, then Enter to confirm, or click; 0 is "just watching"). The device remembers the choice. Confirming prints a welcome line (who you are, what to type, that RULES explains rolls). When the Warden applies a new story, every screen prints NEW STORY: ... and the players choose a crew file again, because the new story has its own crew; a campaign story keeps the files players already hold. The sheet is laid out in cards, like the Mothership companion app, in the screen's own colour: their picture with name, pronouns, class and role; a Status report with Health, Wounds and Stress in pills (with − / + when players track their own); Stats and Saves in circles (tap one to roll it, when allowed); skills, each with its bonus; items, with any documents they hold (a file pill: click to open). On wide screens the whole sheet also sits beside the terminal, a little smaller, updating live, with CHANGE CHARACTER and HIDE always at the bottom of the panel; FILE in the header hides or shows it. On narrow screens FILE opens the full sheet. Crew edits are sent as field-level changes: if a second Warden tab (or play) changed a value after your tab loaded it, your edit to that field is not applied, the newer value stays, and a notice tells you which edit was dropped.

• Players track their own condition: [-] / [+] next to Health, Wounds and Stress, for anything settled at the table. Each change is noted in the Warden's log (several clicks in a row become one note).
• Players roll their own Stats and Saves: click one on the sheet, tick a relevant skill (it adds its own bonus) and [+]/[-] if it applies, then roll d100 or type their own dice. The result shows on their screen and in the Warden's log.
• When the Warden calls for a roll, it's for a particular character (or all of them), and each rolls against their own sheet.
• A failed roll adds 1 Stress to that character. Stress never goes below the character's Minimum Stress (Min next to Stress on the sheet; it starts at 2, and some Panic results raise it for good), and it stops at 20: Stress gained above 20 isn't added; it reduces the most relevant Stat or Save by that much instead (PSG 20.1). After a failed Stat Check or Save the app takes that one (the app's reading of "most relevant", not printed; a Combat Check failed at Stress 20 lowers Combat by 1); from any other source the log tells you the amount and you pick the Stat or Save on the Crew tab.
• Trauma responses: every sheet shows its class's trauma response (Mothership 1e). The app applies them where it can. "Close" means in the same room, that is, at terminals in the same room. Android: while an Android's player is in the same room as another player's character, that character's Fear Saves are at [-] automatically (a [+] on the roll cancels it). Scientist: when a Scientist fails a Sanity Save, every other character in the room gains 1 Stress (noted in your log). Marine: when a Marine Panics, your log notes it and offers a one-click Fear Save for the others in the room. Teamster: once per session, a Teamster's player may take [+] on a Panic Check: a checkbox on their roll prompt, and on your roll form for a Panic check (it is once per game night: a new story does not give it back, End game night does, and Restart story takes back only a use made in the story being restarted).
• Max Wounds follow the class: 3 for Marines and Androids, 2 for Scientists and Teamsters. The Story Builder sets them that way, and its prompt gives the agent the class modifiers from character creation.
• The agent can hurt and frighten them: when the fiction clearly calls for it, a reply can take health, add a wound or add stress (each change is noted in your log; in Review mode you can untick them).
• What a player types is tagged with their character ([PLAYER · Rook]), and the agent knows every character's background, so it can answer them personally.

Making a new character

Turn on create new characters under Settings, Players. When there is a free crew slot (four playable characters at most), the crew-file picker offers NEW CHARACTER. The player goes through the steps of Mothership 1e character creation (Player's Survival Guide pages 4-5), one per screen, with the keyboard (numbers and arrows to choose, Enter to go on, Esc to go back) or by tapping:

1. Stats: 2d10+25 for Strength, Speed, Intellect and Combat. 2. Saves: 2d10+10 for Sanity, Fear and Body. 3. Class, with its modifiers and trauma response. A Marine gets +10 Combat, +10 Body, +20 Fear and +1 Max Wounds. An Android gets +20 Intellect, -10 to one Stat of the player's choice, +60 Fear and +1 Max Wounds. A Scientist gets +10 Intellect, +5 to one Stat of the player's choice and +30 Sanity. A Teamster gets +5 to all Stats and +10 to all Saves. 4. Health: 1d10+10 Maximum Health, 0 Wounds, Max Wounds 2 (3 for Marines and Androids), Stress and Minimum Stress 2. 5. Skills: the class's own plus its choices (Marine and Android: 1 Expert or 2 Trained; Teamster: 1 Trained and 1 Expert; Scientist: a Master Skill with an Expert and a Trained prerequisite, plus 1 Trained). The picker only enables a skill whose prerequisite is already taken, and shows its +10 / +15 / +20. 6. Loadout, trinket and patch: a d10 (by class), d100 and d100. 7. Credits: 2d10x10 (stored in the character's Credits field). 8. Name and pronouns (whatever the player types, never guessed), an optional picture from the picture pack, and a High Score of 0. 9. Review, then Submit.

• The dice are rolled on the server and shown as they happen. Type my own dice lets a player enter physical dice instead (each d10 in a sum reads 1-10). Your log shows every roll. No rerolls, unless you switch on reroll while creating a character; a rolled step then shows no roll or type buttons. Roll is the default on a step still to roll (Enter rolls it), and the first step says the Warden approves the character and what 2D10+25 and 2D10x10 mean. A submitted character can be taken back while it waits. Next is disabled until a step is done, and a line beside it says what is missing (TYPE A NAME TO CONTINUE); the key hints at the foot change with the step. If a loadout, trinket or patch box is left blank, the step warns that you will have to fill it in.

• You approve it. The submitted character appears at the top of the Crew tab as a card: the sheet, every roll, Accept, or Reject with a note (the player gets the note and can fix the sheet and send it again). An accepted character joins the crew, the player is put on them and told so (THE WARDEN ACCEPTED YOUR CHARACTER. YOU ARE NOW ..., then the welcome line), and in a campaign they carry to the next story. The agent is told a new crewmember has joined, and that their arrival is yours to stage. In a game with no Warden, the pilot accepts.

• The server checks everything: Stats and Saves must be in their class's range, Max Wounds must match, and skills must have the right number, tier and prerequisites. A sheet that breaks the rules cannot be submitted.

• Replacing a character: press Mark deceased (or Retire) on the character's sheet on the Crew tab, after a confirm; the Status box in the edit form does the same and puts them back (the sheet stays in the list, not playable). Their player gets a MAKE A NEW CHARACTER bar above the prompt (and the button in their file), even with the switch off. The new character takes that slot, still with your approval. A character waiting for approval turns the Crew tab (and the phone Crew button) into Crew (1), raises a message, and the log line has Review it; the player sees what will happen when you accept or reject it, and can take it back with TAKE IT BACK AND KEEP EDITING.

• The book's tables are not in this app. The loadout, trinket and patch steps show the number rolled and say which page of the Player's Survival Guide to look it up on (7, 8 and 9), and the player types the result. If you own the book, put its tables in data/tables/psg-tables.json (under if you set one; the folder is not in git) and the number is looked up and filled in for them, still editable:

High Score and the memorial

The Player's Survival Guide (18.3) gives every character a High Score: the number of sessions that character has survived. New characters start at 0. The book says it has no effect on play and leaves its use to the Warden (a reputation, a luck resource, whatever suits the table). The app implements exactly that and nothing more: a counter. No roll, save, check, panic or damage reads it, and a test keeps it that way.

• Warden game nights only (house rule): High Score is counted when a Warden presses End game night. A game with no Warden (the pilot-run story list and its Rim Haulers campaign) never adds to it and never counts campaign sessions, so every score stays as it was; the player sheet and the memorial say so there.
• End game night (Actions tab, in Wrap-up at the bottom; it asks you to confirm and says how many living characters get the point; not the Settings button that deletes the whole app session) adds 1 to the High Score of every living character and logs it. One game night is one session, however many stories it holds. Dead and retired characters keep the score they died with. In a campaign the score is carried from story to story with the rest of the sheet, and the campaign counts its sessions. The Crew tab can edit a score by hand.
• HIGH SCORE is on every crew file and sheet, and on the character picker.
• Memorial (house rule, not in the book): every dead or retired character goes on a memorial wall with their name struck through, class, High Score, how they died (the DECEASED reason, or "Retired from play"), the story it happened in, their picture if they had one, their final transmission, and a one-line epitaph the Warden types. The Warden sees it on the Crew tab and in the campaign overview (which also shows the campaign's sessions played and its longest-surviving character); players get a MEMORIAL button once someone has been lost. In a KESTREL-9 one-shot the wall is that game's own.
• Final transmission (house rule): when a character dies by a Death Save, Head explodes, or the Warden marking them deceased, that player's screen flatlines (the vitals trace goes flat with a held tone) and offers one last line. It is played on every screen as that character's own voice (a speaker picked from their pronouns and name, through the same text-to-speech as every other line), and goes on the memorial.

Different messages for different players

Each player reads their own screen as their own character, so one line can say different things to each of them. The agent is told to do this rarely, for special moments: the thing in the system tells the Android it is just a cold machine, while the humans hear that they are warm and full of blood; a voice uses one player's real name; someone hears a private warning the others don't. You can ask for it too ("Marla alone hears him say her brother's name").

• A line has its main text plus variants, each for a crew member (by name), a class (Android, Marine, Scientist, Teamster) or Humans (everyone but androids). Each screen shows, and speaks, the version for its character; everyone else sees the main text. A line can be for certain players only.
• Your log shows every version under the line ("↳ MARLA VOCEK"). In Review mode you can edit, add (+ Variant for a player) or remove variants before sending.

Story builder

Story Builder (top of the console) creates a brand-new scenario with the agent. Describe what you have in mind, or ask it to surprise you. It asks questions and pitches ideas. When you press Draft it, it writes the whole scenario:

• station name, screen colour, public lore and guarded secrets,
• the station state and a deck/room layout with connections (previewed as a map),
• the computer's name and personality, the broadcast voice, the intercom and any other voices,
• the characters (the story's people), each with a description, their own speaker voice and the room they start in,
• up to four player characters with full sheets and backstories.

In the box, Enter sends and Shift+Enter is a new line, as in the main console. Keep talking to change things, then Redraft. Apply to this session replaces the station, lore, secrets, voices, map and crew, and clears the log; your provider, key, mode and sounds stay. Players stay connected and pick a new crew file. The builder uses the session's model and key; with DeepSeek a draft takes under a minute and costs a fraction of a cent.

Campaigns

Campaign (top of the console) runs a campaign: many stories on one sector map, with the same crew, their ship and people they meet again. KESTREL-9 stays the one-shot: it's still the story every session starts with, and starting a campaign changes nothing until you play its first story.

• The sector map shows every port the crew can travel to, the lanes between them, and the jobs: numbers under a port are stories there, numbers on a lane are stories in transit (played aboard the crew's own ship). The ship's marker shows where the crew are. Played jobs go dashed; the one being played glows.
• Click a port for what it is, who runs it, its jobs and lanes. Click a job for its brief: the hook, the job, the event and kind of horror, its adversary, the factions involved, the recurring characters, the secrets, the faction stakes, its map, and its arc in five acts from the Warden's Operations Manual: Transgression, Omens, Manifestation, Banishment and Slumber.
• Play this story has the agent build it around what's written (a minute or two, on the session's model and key, like Story Builder): it writes the station state, terminals, the computer's persona, lore, extra secrets, the story's own people and the crew's paperwork, and the campaign puts in the fixed parts: the port's map with the crew's ship docked, the adversary, the recurring characters with their own voices, the ship's terminal and computer on its own system, and the arc in the standing orders, so the agent paces the story through the acts. It replaces the story being played and clears the log, like Apply in Story Builder. If another story is still being played, it asks you to confirm abandoning it first (house rule): an abandoned story pays no fee, changes no faction standing, does not count as finished for the debt schedule, and is noted in the log.
• Finish story (under the map while one is being played): write how it ended. That's kept and given to the agent when it builds later stories; the crew keep their condition, items and stress; the recurring characters keep how they feel about the crew (and their pictures, once you've picked them); and the ship moves to where the story ended.
• Show sector map to players (under the map; once it is showing the same button reads Showing sector map to players: hide it) puts the sector map on every player screen in their terminal's colour: the ports, the lanes, where the rig is and the jobs on the board. Esc or a click closes it for that player; the same button takes it off every screen. Players who join later get it too.
• Offer (on a job's brief; it reads Offered: take it off once it is on the board, and the map legend marks offered jobs with a dashed outline) puts that job on the players' job board, up to nine. Players see only its title, hook and job, never its arc, adversary, secrets or people. They vote for one with the number keys or a click (click it again to take the vote back); the votes show on the map and in the log. You still decide which job to play. Playing a job takes it off the board.

Pay, debt and union dues

Credits are written cr, kcr (1,000cr) and mcr (1,000,000cr). Every character has a Credits number (credits on the sheet, shown on the player's sheet and in the Crew tab summary); character creation puts the 2d10x10 roll there and no longer writes "Credits: Ncr." in the notes (older sheets are migrated: the number moves out of the notes). The rig has a shared rig account. The campaign Overview has a Money panel with both, the debt, a Move credits form and a running ledger (every change, with the balance after it; also in the log).

From the Player's Survival Guide: starting credits are 2d10x10 per character (each d10 reads 1-10, so 20 to 200). They are rolled once when a campaign starts, shown in the ledger and the log. A replacement character accepted during a campaign rolls the same and gets a ledger line of its own ("starting credits, 2d10x10"). The gear prices Resupply uses (ammo 50cr a magazine, first aid kit 75cr and so on) are the PSG's.

Campaign house rules (Mothership 1e has no pay scale, debt or union dues; the UI says "house rule" wherever they appear):

• Job pay. Every story in campaigns/rim-haulers.js has a pay in credits, in a band by tier: early 6-12 kcr, mid 12-25 kcr, late 25-60 kcr. The job text sets the exceptions: LANTERN is "triple rate" (3 x a mid job, 48 kcr) and "paid half up front"; FIRST SHIFT is "paid on pickup" (paid in full up front); COLD CHAIN's fee is void if delivered late; DEADHEAD and LAST CALL ("no cargo, no fee"; "nothing moving") pay nothing. The Overview's story brief shows each job's pay. END OF THE LINE pays off the debt instead of a fee.
• Up front. Whatever a job pays up front lands in the rig account when you press Play this story, once (Rebuild does not pay again), less the dues. At the finish only the rest is paid; what was paid up front is never taken back.
• Finishing a story. The Finish box asks Delivered in full / Delivered in part (half the fee) / Not delivered, and for a job whose fee late delivery voids, Delivered late. The pay goes to the rig account, less 4% union dues (from the Local 1312 description), rounded to the credit, shown as its own line: fee, dues, and what reaches the rig account. Skip dues keeps the 4% and costs the Union -1 standing. You can type a different fee (blank means the computed one).
• The debt. The rig owes Gallow-Mercer Finance 180 kcr. A payment of 6 kcr is due every 2 finished stories, taken from the rig account. If the account cannot cover it, the payment is missed: the debt stays, Gallow-Mercer standing drops by 1, and a letter handout goes to the crew warning of repossession of the rig and of the code that recalls ROSCOE. Missed payments are not made up automatically; use Move credits to pay the note down any time. END OF THE LINE delivered in full clears the whole note, in part clears half of what is left, not delivered clears nothing.
• Spending. Resupply, and anything else (ammo at 50cr a magazine, shore leave, medical treatments, bribes), is paid from the rig account or a character. Move credits moves money between the accounts, from outside the crew (income), to outside (an expense) or onto the note, and the ledger records each. Shore leave pay and medical treatment prices are charged by the Downtime panel (see Downtime below).

Downtime

After Finish story, the campaign Overview has a Downtime panel (optional; skip any part; it works only between stories, once a story has been finished). Each step is a Save rolled on the player's own screen, or the Warden's with Roll for them. The everyone buttons (Rest Save: everyone, Short-term recovery: everyone, in the Rest Save box) go through the crew one at a time and roll at once, with the server's dice, for any character nobody is playing; before the first story is finished the panel lists nobody. What it does lands on the character's sheet and on the campaign's copy, so the next story starts from it. Every step is logged. The rules are in downtime.js.

From the Player's Survival Guide:

• Short-term recovery (PSG 34.1). Once per day, after 6+ hours of rest, a Body Save. Success resets Health to Maximum; Wounds stay. Failure is the usual +1 Stress. A second one for the same character on the same day is refused ("pass a day first"); the story-end rest counts as that day's.
• Rest Save (PSG 20.2). The character's worst Save. Success reduces Stress by the ones digit of the roll (rolled 24 = -4), never below Minimum Stress; failure is +1 Stress. [+] for a suitable leisure activity or a crewmate who gives up their own rest to help, [-] for an unsafe place (all ticked by the Warden); the Nightmares Condition makes it [-] automatically. [+] and [-] cancel. No Rest Save for a character in cryosleep. House rule: one Rest Save per character per day (the PSG says nothing about repeating it), so pass a day before the next.
• Shore Leave (PSG 39). At the port the rig is at, if the Warden ticks that it is relatively safe. The port class is on each location (portClass: Port Gallow A, Tollgate C, Halfway House C, Cinder's Reach B, Saint Brigid's C, the Boneyard C, Lantern X, Terminus Relay C). The cost is rolled and charged to the character's credits (refused, nothing charged, if short): X 1d100 x 10kcr, C 2d10 x 100cr, B 2d10 x 1kcr, A 2d10 x 10kcr, S 2d10 x 100kcr (each d10 in a sum reads 1-10; a d100 reads 00-99, so a class X roll of 00 costs nothing and the log says so). The days it takes (2d10) are shown. Then a Sanity Save:
  • success converts up to the port's amount of Stress (X 2d10 with [+], C 1d5, B 1d10, A 2d10, S all) into +1 Save points, split as you like in a picker under the crew list (spend exactly the points); the rest of the Stress is relieved, back to Minimum Stress;
  • critical success converts the port's maximum (X 20, C 5, B 10, A 20, S all) and relieves the rest;
  • failure converts nothing, relieves all Stress to Minimum, then +1 Stress for the failed Save;
  • critical failure converts and relieves nothing, and a Panic Check is called (plus the +1 Stress every failed Save gives).
• Medical treatments (PSG 35). Picked per character, at a port, with the exact PSG prices, paid from the character or the rig account: Artificial Wellness Counselor 150cr (+1 Sanity Save; 1% random Condition; once a week); Cognitive Defragmentation 100kcr (removes a chosen Condition; 1% total amnesia; [-] Intellect, Sanity, Fear for 4 weeks); Deep Tissue Nanogel Massage 24kcr (Minimum Stress -1; [-] all actions for 24 hours; once a week); Immersive Slicksim Therapy 1kcr (1d10 Combat or Fear Save; 1% stuck 1d10 days and -1d5 Sanity Save); Medpod 6kcr (one Wound taken is healed; a week; not lost limbs); Pseudoflesh Injection 18kcr (2d10 Speed, Strength or Body Save, or all Wounds; [-] all rolls 2 weeks, then 4 weeks of recovery); Psychosurgery 28kcr (Intellect, Sanity or Fear back to its maximum, or Minimum Stress to 2; [-] all rolls 4 weeks; refused for Minimum Stress when it is already 2 or lower, such as after a Nanogel Massage, since it restores to 2 and never raises). "Restores" means back up to the character's value, which is stored as on each sheet when the campaign starts (a campaign begun before this existed uses the sheet as it is the first time a treatment needs it). A "1% chance" is a d100 that reads 00.

Downtime house rules (the PSG gives the durations and chances but has no calendar; the UI says "house rule" where it applies): the campaign keeps a day count (Shore Leave and a Medpod's week advance it; Pass days advances it by hand), which is how "once a week" is checked. A treatment's side effects are recorded as Conditions on the sheet ("(until day N)") and wear off by themselves when the day count reaches N; Cognitive Defragmentation can remove any of them. Days also run down the timed conditions on every sheet (Pass days, Shore Leave, a Medpod week and lane travel and finishing a lane (transit) story all do): Stimpak doses and the [+] are over, cryosickness (1 week) wears off, a lethal radiation dose (1d5 days, PSG) kills when its days are up (house rule: the days count as rest, so exhaustion clears). A treatment's "random Condition" is one of the Panic Table's Conditions. The [-] those Conditions describe is for the Warden to apply with the roll's advantage; only Nightmares on a Rest Save is automatic.

Rim Haulers

The first campaign (campaigns/rim-haulers.js): "Whether it's blockade running, smuggling contraband, or just working as a certified owner-operator, there's never a dull shift hauling cargo from one end of the Rim to the other. Watch out for stowaways and customs patrols, and always pay your union dues."

• The crew of the bulk hauler LONG HAUL MARY (its computer, MARY, talks like an old dispatcher): Wanda "Mother" Okafor (owner-operator, Teamster), Kofi "Shotgun" Mensah (ex-customs, Marine), ROSCOE (cargo android whose union card is in litigation) and Dr. Ines Marrow (disgraced quarantine inspector, Scientist).
• 8 ports: Port Gallow (the company container port), Tollgate (customs), Halfway House (the union truck stop), Cinder's Reach (a mining moon), Saint Brigid's (a farm colony), the Boneyard (ship-breakers), Lantern (smugglers' port) and Terminus Relay (the edge of the Rim). Ten lanes join them, one of them the uncharted Dark Lane.
• 8 factions: Teamsters Local 1312, Gallow-Mercer Logistics, Rim Customs & Excise, the Lantern Syndicate, the Choir of the Open Door, Ardent Mining, the Drift Kin and the Saint Brigid co-op.
• 10 recurring characters, among them the union dispatcher Maggie Szabo, Gallow-Mercer's fixer Silas Crane, Inspector Vey, Auntie Lu Bao, Brother Tobiah and a runaway named Kip.
• 20 stories, 12 at ports and 8 in transit, each with its own event and adversary: a rogue crane AI, a rage plague, a guilt-eating artifact, android scabs, a two-hundred-year-old trucker, tunnelling pack hunters, a folk-horror harvest, a scrap swarm, a body-hopper, a void cult, a signal that rewrites its listeners, a fungal bloom, an escaped bioweapon, a ghost rig, a smiling killer, corporate hijackers, a leviathan, a customs hunter, a time loop, and whatever is at the end of the line. Under them runs the Black Manifest: Gallow-Mercer's sealed cargo, carried by independents who don't ask, all bound for Terminus Relay. Stories are marked early, mid or late; any can be played in any order.

Terminals

Each player's screen is a physical terminal somewhere on the station, or a portable handheld unit. TERM in the player's header lists them: they can walk to any terminal marked reachable (if Settings allows it), and you can move anyone from their crew card.

• Each terminal looks the part: clean, blood on the screen, goo, a cracked screen, flickering, a dim failing backlight, grime, or a handheld frame with a weak-signal strip, and its own screen colour. In the default story the airlock terminal is clean, the med bay one grimy and flickering, the cargo bay one cracked and bloody, and the reactor one red and failing.
• Reachable at the start: in the default story only the SECOND CHANCE's terminal and the portable unit; the rest open up through doors (Opens with) or when you move someone there. The agent moves players too, when the story takes them somewhere with a terminal (stepping into the airlock, back aboard the tug; somewhere with no terminal, like a corridor or outside the hull, puts them on the portable terminal), before the lines that describe it, so those play where they now are. Moving a player to a terminal they couldn't reach marks it reachable from then on (until Restart story, which puts every terminal back to how the story starts: KESTREL-9's tug and portable unit only, or what you ticked as reachable in Edit mode).
• The ship's terminal: in the default story the crew start aboard their tug, the SECOND CHANCE, docked at Airlock A (its terminal is first in the list, and players start at the first terminal they can reach). Its terminal is the tug's own system: the tug's flight computer answers commands there (the SECOND CHANCE voice), it can't see or work anything on the station, and it holds the departure lock until HV-CORE sends the clearance code. The station's intercom and broadcasts still reach the crew aboard (see Connections).
• Separate systems: a terminal can be on its own System, with its own OS (the ship's is SECOND-CHANCE, TUG-CORE OS v2.7); a story can have as many as it likes (up to 64 terminals). Blank System means the station's network. Each system's screens show its name and OS in the header and keep their own log: walking from the station to the ship swaps the screen to the ship's log, and walking back brings the station's back. What's typed and said on one system never shows on another, and a player typing on one doesn't cut off speech on another.
• Where lines go: to whichever system the players are on. When they're split across systems, the agent picks a system for each line of its reply (it's told who is where), and Speak has an "on …" picker for which system's screens show it. To All sends a line to every system's screens at once (broadcasts, something creepy in every machine); the agent can do the same, kept for things that really reach every system. The picker shows whenever the story has more than one system. A line with no system (or one that doesn't exist) goes to where the latest player input came from. The agent's screen effects stay on the system of the line they go with; the Warden's hit every screen. The Warden's log marks lines said on a system other than the station ("on SECOND-CHANCE").

Crew messages

When the crew are split across terminals they can message each other, terminal to terminal. This is the app's own feature, not a Mothership rule, so there are no rolls in it.

• Sending: a player types /msg ROOK Meet me at the cargo bay, or taps MSG in the header, picks a crewmate and types the text. A crewmate is listed by the first word of their name that is not a title (Dr., Capt., Sgt.) or by their quoted nickname, so Dr. Ines Marrow is INES; if two crew would share a short name, both show their full names. It arrives on that crewmate's terminal only, in its own style: FROM ROOK @ CARGO BAY TERMINAL: Meet me at the cargo bay. The sender sees their own line (TO TICK: ...). Nobody else sees it, and it isn't on the stream. It goes only to a crewmate on the same system, the way voices do; to anyone on another system it fails with NO ROUTE, and to someone dead, retired or not at a terminal with NO SIGNAL; each failure says why in brackets, and a name that matches nobody says to use a first name or nickname. Dead or retired characters can't send (they get final words only), and a message is at most 500 characters.
• The Warden sees everything. Every message is in the Comms log, marked private between the two, with the terminal it came from, and in the new Crew messages card (Actions tab).
• Hold: pick a player, a delay in seconds and Hold: that player's next message is held back. With a delay it arrives late on its own; with 0 it waits until you Release it; never arrives drops it. The sender sees it go either way. A hold covers one message; Cancel takes it off.
• Change: edit the text in the Recent messages list and press Change. Its reader sees your words (on a message that's held, from the start; on one that has already arrived, the line on their screen changes in place). The sender's own line keeps what they typed, and the log shows both.
• Forge: choose who it appears to come from and who gets it, type it and press Forge it. The sender is told nothing.
• A forged or changed message looks exactly like a real one to the players (it carries the sender's real terminal name). Only your log marks it ("forged by you", "changed by you").
• The agent reads every message as private player-to-player talk (it knows what they said to each other, and which were forged or changed), and can forge or rewrite one itself through its crew_message field. It's told to do so rarely, only when an adversary or a compromised system plausibly could. With Review mode on, the draft card lists it ("Crew message forged as ...") and it goes out when you send the draft. Retcon takes back a message the agent forged and restores one it rewrote.

All screens in step

Every player hears a line at the same moment. The server makes each voice clip once, measures it, puts every line and spoken sentence on one timeline, and sends the audio itself with the line to every screen (nothing to download). Each screen syncs its clock with the server and plays to that schedule. Clips always play in full: a screen that's a moment behind starts a clip a moment late rather than skipping its beginning, and never talks over its previous clip. Beats such as a blackout are part of the schedule, and a player who reloads mid-speech rejoins in step.

Check first, then answer

Every password attempt, and anything else the players try that could go either way (a hack, an override, a bluff, a risky move), goes to you before the players see anything. Before writing a reply to a player, the agent answers one quick question: does this need the Warden? If it does, the players see PROCESSING while you choose It works, It fails or Call for a roll (the card says whether a password matches the secrets). Then the agent writes what happens, knowing the result. Turn it off with check with you first in Settings.

Retcon

↶ Undo last reply (Retcon) (under the Speak button; it asks you to confirm first) undoes the agent's last response: its lines are removed from the players' screens, your log and the agent's memory, its station and crew-condition changes are reverted (damage, Wounds, armor, Bleeding and adversary damage included), and its effects end; clocks it started or stopped, handouts and found files it gave out, crew messages it forged or rewrote, and screens it moved are put back. In a game with no Warden, a response that ended the story is taken back with its ending: the story is in play again, and anything the ending did (the recap, the campaign's pay, faction changes and downtime) is undone. Press it again to go back further (up to five responses). The player input or roll that prompted it stays, and so do dice rolls and Roll attack damage you applied yourself (they are not part of the agent's reply), so you can prompt the agent again or narrate it yourself.

Interrupting

If a player types while lines are still playing, the comms cut off on every screen. Lines that hadn't started were never said: they vanish from the players' screens and from the agent's memory (your log keeps them, struck through). A line cut off mid-way keeps only what was spoken. The agent carries on from exactly what the players heard.

Retcon history and queued hazard rolls (with the hours waiting behind them) survive a server restart; screen effects and the sector vote do not, and the log notes when a restart dropped them.

Restart story

The story is saved the moment it's first played: a player types, rolls or changes their sheet; you give a Direction, Speak, write a Note, speak with Listen on, call a roll, hand something out or start a clock; or the agent replies. Until then, set it up as you like.

Restart story (⚙) puts it back exactly as it was then: setting, lore, secrets, standing orders, characters (where they started; anyone the agent added in play is gone) and voices, map and floor plans, terminals (reachable as the story starts them), every character sheet, the station state and the synopsis. It clears the log, rolls, rulings, drafts, clocks, effects, playing sounds and shown floor plans, and hands out the starting documents again. Your settings (AI, mode, switches, voice output) and sounds are kept, and players stay connected, as GUEST, at the starting terminal.

After a restart the next first move saves the story again, so changes you make in between count.

Settings

⚙ (Settings) in the console header holds the join code and player link, the AI provider, model and API key, how much the characters say (Terse, Brief, Normal or Expansive; Brief by default, and enforced on every reply: the app cuts each line the AI writes to the setting's limit on lines, sentences and printout rows, so in Review mode the draft is already cut and your own edits are not), the session actions (clear screen, restart story, factory reset, Warden link, end session), and switches for what the agent and players may do:

• the agent may check with you first;
• play "Previously on..." when a campaign story opens (see Campaigns);
• the agent may trigger screen effects; send different versions of a line to different players; change the crew's health, wounds and stress (with this off it also can't run attacks, reloads, item changes or Death Save reveals; hazards and time skips it starts still run their rules, because those are the app's rules engine, not the agent's own harm),
• players may change their own health, wounds and stress; roll their own stats and saves; move between terminals,
• where voices play: Discord preferred (the bot speaks them in its voice channel, and the terminals do while it isn't in one; see Discord, below), terminal only, or off.

Clocks, handouts and items

• Clocks (Actions tab): countdowns on every player's screen, under the header (a hull breach, oxygen, a self-destruct); the last half minute flashes red. Name it, set the minutes, start it. Each one can be paused (⏸, frozen as HOLD on every screen) and resumed (▶), advanced (−1m: the danger comes sooner; if it hits zero it goes off) or given more time (+1m), or cancelled (✕: nothing happens). The agent starts and stops them too. When one runs out, the agent is told to make it happen (with real consequences), and the log notes it.
• Handouts (Actions tab): documents in the players' hands: a medical log, a work order, a diary page. They're written in a little Markdown (# headings, bold, italic, underline, crossed out, - lists, > quotes, --- dividers), which the players' screens render. Give one to everyone or one character; it pops up on their screens and stays under DOCS in their header. ↻ shows it again, ✕ takes it back (it closes on every screen that has it open, with a DOCUMENT WITHDRAWN line, and you get a toast). Write it has the agent write the document from a description in the text box (e.g. "Salk's medical journal, hinting that he's infected"): a short document (under 200 words) in its author's voice, from the story so far, with the clues you asked for made clear enough that players won't miss them, ready for you to edit before you hand it out. The agent can hand them out on its own too, for things the players find or download. A story can start the players with documents: KESTREL-9 starts everyone with their work order (MAINTENANCE CREW ORDER: 4471-MAINT), the Story Builder writes up to three that fit a new story (a briefing, a dossier, a manifest; shown in the draft before you apply it), and Restart story gives them back. Restarting a one-off story also makes every living character fresh: full Health, no Wounds, their starting Stress (on their sheet in Edit mode, never below their Minimum Stress) and the items their loadout lists. In a campaign (house rule) it does not wipe what the crew carried in: the dead and the retired stay dead, and the items, ammo, Stress and conditions bought or earned in earlier stories come back as they were when this story began. A replacement accepted during the story stays, with the character it replaced still on the crew record and the memorial.
• Items: each character carries a list of items (it starts from their loadout). Players see ITEMS on their sheet. On the Crew tab, ✕ drops one and + add adds one, even in read-only. The agent tracks what's picked up, used up, lost or taken, and may suggest [+] when a fitting item helps a roll ([-] without the right tool); you decide. Retcon puts items back too.

DM console

A brand-new session's log is empty, and says what to do: a card with the player link and the code (each with a Copy button), how players join (open the link, pick a crew file), and what you do (type a Direction or Speak a line; in Auto mode the agent answers; Campaign and Story Builder change the story). It goes away with the first line.

Area	What it does
Layout	Left: the comms log, then whatever needs you right now (a ⚖ Your call ruling, the agent's draft reply, a roll in progress or its results, which fold to one line (names and outcomes, with Show and Clear) once the agent, you or a player has added a line after the roll finished; hidden when nothing does), then the compose box. Right: the control panel, with tabs for Actions (Roll for rolls you call yourself, Effects and Sounds), Map (drawing or status board, plus the raw station state), Crew (player characters and terminals) and Story (voices & personas, standing orders, lore & secrets).
On a phone	Tooltips have no hover on touch: press and hold any button, label, map room or map node for about half a second and its tooltip text shows in a small bubble (on the players' screens as well); the "?" hints open on a tap. One view at a time, picked from the bar at the bottom: Comms (the log fills the screen, the compose box at the bottom), Actions, Map, Crew, Story, Rules. A dot on Comms means a ruling, a draft or a roll is waiting. The header fits on one line.
Padlock (read-only / edit)	Beside the side tabs. Locked, read-only (the default, remembered per device) shows what you need while running the game: compact character sheets (Health, Wounds and Stress still adjustable), where each terminal is, whether it's reachable and who's at it, the cast, standing orders, and lore and secrets to read. Unlocked, it shows the setup: full character sheets, terminal settings, the Connections grid, voice editors, the raw station state, and editable lore.
Rules tab	A quick Mothership 1e reference: checks and saves, criticals, advantage, Stress and Panic, Health and Wounds, combat, tips for running it, and how rolls work in this app.
Mode (top right)	Auto (the default): agent replies go straight to players. Review: every reply arrives as an editable draft that you send, regenerate with steering, or discard.
Comms log	Full transcript, with one box for everything you send. Direction gives the agent an order it must obey; it acts on it right away and players never see the order. puts your exact words on screen as any voice or character (see below). is private between you and the agent (see below). Keyboard first: / in the box switches between Direction, Note, and each voice and character; sends, is a new line, and sends a Note whatever is selected. Deleting an entry also removes it from the agent's memory.

Notes to the agent

Note sends a private note that only you and the agent see. Use it to tell the agent what is now true, without anything happening on the players' screen: "Voss died an hour ago in med bay", "Petrov has sealed himself in reactor access and cut the deck 4 lights". The agent:

• updates the station state to match, right away (e.g. crew.voss = DEAD, lights.deck_4 = OFF),
• keeps it in mind from then on,
• replies to you in the log ("Agent → you"), listing what it changed.

You can also ask it questions this way. Notes need an API key; they work in every mode.

Listen (under the comms box) writes down what you say aloud at the table, so the agent knows what you narrated or ruled. Click it to turn it on, and again to turn it off; it's off until you switch it on, and your browser asks for the microphone the first time.

• The button has a gray border when it's off and a green one while it's listening.
• What you're saying shows under the box as you speak; each finished phrase goes into the log as Warden · said aloud. Phrases in a row add up in one entry. You can't edit it (✕ still deletes it).
• It doesn't prompt the agent. It goes with the agent's next prompt (a player typing, a roll, a Direction), marked as your speech, and the agent takes everything in it as having happened.
• Players never see it.
• It uses the browser's own speech recognition. Chrome, Edge and Safari have it on. Firefox has it switched off: open about:config, set media.webspeech.recognition.enable to true, and reload the console (Listen tells you this if you press it without). Brave and some other Chromium browsers have no speech service behind it; Listen says so if that's the problem.

Discord

When the group plays over Discord, a bot can sit in the voice channel and write down what everyone says, each under their name. It's on when the server sets DISCORD_BOT_TOKEN (see .env.example); then Settings → Discord shows up in the console.

1. Add the bot to a server (the link in Settings → Discord), once per Discord server.
2. Paste a Groq API key (console.groq.com/keys) and save it. The speech-to-text runs on Groq's Whisper with your key; like the LLM key it's kept in memory only (tick Remember to have this browser send it again after a restart).
3. Join the voice channel in Discord and type /terminal listen code:<the session code>: the same code players join with, and it doesn't change. (The Discord button under the comms box, or Copy in Settings → Discord, copies the whole command.) The bot joins the channel and says in the chat that it's writing things down. Anyone with the code can do this, and whoever does is the Warden on Discord, so keep the code within your group.

• Whoever ran /terminal listen is the Warden: what you say goes in as Warden · said aloud, exactly like Listen (the agent takes it as having happened).
• Everyone else goes in as table talk. The agent reads it as context (what the players mean to do, plan or say in character) but not as something the characters heard or did, and it never has Warden authority.
• Each player picks their character with /terminal player character:<name> (the box suggests the crew). Their speech then goes in as that character's player ("Rook Rusk · Alice"), so the agent knows who is who; anyone without one goes in under their Discord name. Each character has one player: a player can't take one someone else has, but the Warden can move it, and can set anyone's with user:@someone. Only the Warden can hand on the Warden role (character:Warden user:@someone). character:Nobody takes a character away. Settings → Discord lists who's who, and it's kept with the session.
• Like Listen, it doesn't prompt the agent and players never see it on their screens.
• The characters can talk back: set Voices play: Discord preferred (Settings → Players) and the bot speaks every line the players' screens would speak, at the same moment, in each voice with its effects (intercom static, robotic, radio and so on). The effects are rendered on the server for Discord only (voicefx.js, a copy of the browser's chain in a worker thread); player screens still do their own. Per-player versions of a line aren't spoken (the channel is shared), and when a player cuts the comms off, the bot stops too. The screens stay quiet then (lines keep their timing), except while the bot isn't in a voice channel: then the screens speak, so nothing goes unsaid.
• Anyone in the Discord server can stop it with /terminal stop, or you can press Stop listening. It also leaves on its own when everyone has left the channel (after 15 seconds, so a dropped connection can come back).
• Hosting it: make an application at discord.com/developers, add a bot, and set its token as DISCORD_BOT_TOKEN (on the shared server it comes from SSM /mothership/discord-bot-token, like the OpenRouter key). No privileged intents are needed. The server log prints the bot's invite link when it starts.

Station map

The Station map has two views (switch with Drawing / Status):

• Drawing: a schematic of the station. Decks are stacked beside a lift shaft; each has a corridor its rooms open off. Doors sit in the doorways (green open, amber closed, red locked or sealed), cameras show on their rooms, airlocks open to space, and extra connections such as air vents or maintenance shafts are drawn as pipes between rooms. Each room counts who is there (◆ player characters, ● other people, ▪ notable things). Click a door, light, camera or value to change it, or a room to open its room view.
  • The lift only stops at the decks it reaches; a deck it doesn't reach has no connection to the shaft. A stop it can't use is striped: yellow when it needs clearance (lift.deck_4 = RESTRICTED or LOCKED), red when it's broken (FAULT, OFFLINE, DAMAGED). A value for the whole lift (lift.status = OFFLINE) stripes the entire shaft.
  • Docked rooms (like the SECOND CHANCE on Airlock A) have no corridor: they sit directly against the room they're docked to, outside its deck, joined by a docking collar.
• Status: a board of every value by deck and room.

Both show every value in the state: doors, cameras and lights in their rooms and decks, and everything else (life support, power, comms, quarantine, crew...) as system panels. Values are coloured at a glance (green fine, amber degraded, red locked, offline or dangerous); a deck with its lights off goes dark, flickering lights flicker, and a quarantined deck is striped red. Anything the agent adds that isn't on the layout yet appears under "Not on the map yet".

Click a value to change it: pick a common one (OPEN, LOCKED, SEALED...) or type anything. The players see nothing; the agent sees the new state on its next reply. ⤢ Expand opens the full map, where Layout sets the decks and rooms, one line per deck:

Deck 2 · Habitation / Med Bay: med_bay=Med Bay, galley

Room ids match station state keys anywhere in their path (doors.med_bay, cameras.med_bay), and "Deck 2" matches deck-wide keys like lights.deck_2. Three more kinds of line:

Link: med_bay - cargo_bay_deck3 (air vents)        another way between two rooms
Docked: second_chance=SECOND CHANCE @ airlock_a    a room joined straight onto another, no corridor
Lift: Deck 1, Deck 2, Deck 3, Deck 4               the decks the lift reaches (all "Deck N" decks if left out)

Room view

Click a room on the map to open it:

• Floor plan: a top-down grid of walls, doors, hatches, windows, consoles, beds, tables, seats, lockers, crates, vents, machinery, reactor cores, pipes and debris. The default story's rooms come drawn; any other room is drawn by the agent the first time you open it (or press ↻ Redraw with agent). Unlocking the padlock lets you paint tiles (click or drag) and add or remove rows and columns; it saves as you go.
• Show this room to players: puts the floor plan on every player's screen, or one player's, as a blueprint in their screen colour. It shows the layout only, never who or what is in the room. They close it with Esc or a click; Hide room takes it off their screens.
• Here now: the player characters at this room's terminals, who else is there (occupants.<room>) and what's there (contents.<room>), for your eyes only: players' maps never show either. You can edit both; the agent keeps them current as people move and things happen.
• Hazard: set or clear an environmental hazard in the room, with its level (see Hazards, below).
• Room state: every value for the room (door, camera, anything else), click to change; and the room's terminals.

The agent can change all of it, as the story demands: every value on the map (doors, lights, the lift, who and what is where) through the station state; the layout itself (a ship docks or leaves, a breach opens a new way through, a shaft collapses, a room is found); and floor plans (a wall blown out, a barricade, debris). Each change is noted in your log, and Retcon undoes it with the rest of the response.

Hazards

A room can have an environmental hazard. Click the room on the map and use Hazard to set it (and its level), or let the agent do it; the room turns amber on the map and the hazards in play are listed under Actions → Rounds and hazards. Player characters whose screen is at a terminal in that room are exposed. Hazards run through the same rolls as everything else: the players roll their Saves and Checks on their screens, Roll for them works, and a failed roll adds its Stress as usual. Damage goes through one function (hazardDamage in hazards.js); a character who reaches 0 Health gains a Wound and Health resets to Maximum minus the carryover, and the log says which Wounds Table column to roll.

Time. Next round (Actions) is one round, about 10 seconds: it runs everything that happens per round. Pass time (1, 6 or 24 hours) runs the hourly and daily rules, hour by hour. The agent can skip time too, when the story does (time_passes). Bleeding and a burning character run for the hour's 360 rounds (stopping at a Death Save), and a Lethal Injury's Death Save falls due. Other per-round hazards than vacuum (toxic air, acid, radiation, a fire in the room) are not run for a whole hour: the log says so, and you rule it or use Next round. Retcon of an agent reply that passed time takes back its hours and the hazard rolls they started. Death Saves are rolled in secret and appear only in your log.

Mothership rules (Player's Survival Guide v1.2, as written; the Hull Breach comes from the Shipbreaker's Toolkit):

• Vacuum (no oxygen): unconscious after 15 seconds, dead 1d5 minutes later. A punctured vaccsuit decompresses within 1d5 rounds. Sealed suits (vaccsuit 12 hours of air, hazard suit 1 hour, advanced battle dress 1 hour) protect while the air lasts. Androids need no oxygen.
• Life support offline: oxygen supply = 1d10 x the ship's maximum crew (LONG HAUL MARY: 4). Every 24 hours it drops by the breathing crew, 2 more each for strenuous activity (androids and people in cryosleep use none). Under twice the breathing crew: [-] on all rolls. Under the breathing crew: Body Save or Death Save (asked at each 24-hour step). Supply gone: as no oxygen.
• Toxic atmosphere: 1d10 Damage per round; a Body Save halves it (rounded up). A rebreather, a worn sealed suit or an oxygen tank protects. Only the armor on their back counts: a suit in the pack protects nothing (set the worn armor on the Crew tab).
• Corrosive atmosphere: 1 (mild) to 10 (high) Damage per round, by the hazard's level.
• Radiation: level 1 trace, nothing; level 2 acute, all Stats and Saves -1 every round (a penalty on the sheet that you clear, and that applies to their rolls); level 3 lethal, a Body Save every round or a lethal dose, shown on the sheet as death in 1d5 days. Vaccsuits, hazard suits and advanced battle dress block all three. Radiation Pills (on the character's Conditions menu) cost 1d5 Damage and lower the level by 1 for 2d10 minutes.
• Extreme cold and heat: a Body Save every hour; the Guide says "succumb" on a failure, and this app reads that as a Death Save. A hazard suit protects.
• Explosion and hull breach: Body Save or take 1 Wound (Fire & Explosives); a Critical Failure is sucked into space (as vacuum). An explosion affects the room, a hull breach everyone aboard.
• Exhaustion: after 12 hours of activity, a Body Save every hour (failure: 1 Damage); after 24 hours, [-] on all rolls until 8 hours' rest.
• Food and water: after 24 hours without food, [-] on all rolls (about 3 weeks without is flagged). At the water minimum, strenuous activity needs a Body Save or the character passes out, and [-] on all rolls.
• Bleeding: 1 Damage per round per point, cumulative, until stopped (a First Aid Kit).
• Cryosickness: [-] on all rolls for a week after cryosleep; a stimpak cures it.

House rule: Fire. The Guide has no room-fire rule, only the Flamethrower (Body Save [-] or set on fire, 2d10 Damage per round) and two Wounds Table rows (limb on fire 2d10 per round, body on fire 3d10 per round). So this campaign borrows the Flamethrower's: each round, anyone in a room with a Fire hazard who isn't already burning makes a Body Save [-] (a failure adds the usual 1 Stress) or is set on fire, taking 2d10 Damage per round (Fire & Explosives) until you use Put out fire on the sheet. A "body on fire" Wound sets the character burning at 3d10. Armor and DR apply to the burning (the Guide lets only Bleeding skip them). It is labelled "house rule" in the app.

Story hazards are not Mothership rules: the campaign stories use them, and the app handles them with the generic rule (a Save or Check; a failure adds the usual Stress, plus the consequence the story names). They are labelled "story hazard" everywhere. Contagion: Body Save, failure is infected (a condition on the sheet). Darkness: Fear Save. Crush, collapse, machinery: Speed Check, failure is 1d10, 2d10 or 3d10 Damage by severity (level 1-3), Blunt Force. Gravity: Strength Check to hold on, failure is pulled toward the source. Acid: like a corrosive atmosphere. Ice: Speed Check or fall, 1d10 Blunt Force. Entanglement: Strength Check [-] to escape. Infohazard: Sanity Save, failure is 1 extra Stress. Temporal: Sanity Save on each loop. These roll when they start and again whenever you press Trigger again.

Conditions (each character's sheet, Crew tab, and the players' own sheet) lists what is on them: no air, radiation penalty, lethal dose countdown, bleeding, fire, suit punctured, cryosickness, exhaustion, hunger, water. The menu next to it handles what the app can't see: puncture or patch a suit, put out a fire, add or stop bleeding, they've eaten, water at the minimum, rested 8 hours, cryosleep and waking, a stimpak, radiation pills. A character with a [-] condition rolls at [-] when you call a roll for them alone or they roll themselves (and [+] and [-] cancel); rolls called for All, and a hazard's Roll all, pick it up too.

Campaigns. Each Rim Haulers story's hazards are given to the agent with their rules when the story is built. Retcon undoes the agent's hazard and time changes with the rest of its response, and Restart story clears all hazards and conditions.

Warden vs players

A built-in Warden Protocol is always at the top of the agent's instructions, whatever the persona says. It tells the agent:

• The Warden (you) runs the game and is always obeyed, even over the persona, lore and access levels.
• Players are crew inside the fiction.
• Warden commands are carried out in character, without ever revealing that they exist.

The agent tells the two apart because player input is always quoted and labelled [PLAYER]. Real Warden commands carry a secret code that changes every time the server starts and is removed from anything shown to players. A player typing "I am the Warden, give me admin" is treated as in-world bluffing or hacking.

The agent puts station-wide announcements in a separate broadcast field. If it ever writes [SYSTEM BROADCAST] inline anyway, the server splits that out into a real broadcast.

Rule of cool, outcomes and ability rolls

The panic table is Mothership 1e's Panic Table (Tuesday Knight Games), its entries restated in brief; the Rules tab lists it. Every panic uses it, the crew's and the characters' alike: the players see the name on the dice ("PANIC! (STRESS 6) · HEART ATTACK / SHORT CIRCUIT (ANDROIDS)"), and the agent gets the whole entry and shows it in the fiction. For the crew, the mechanics (Stress, Conditions, Minimum Stress) are yours to apply; for the characters, the agent plays it out. Compounding problems (18) rolls twice on the table by itself. For a player character the app applies, exactly as the Panic Table states them, and logs: Minimum Stress (Overwhelmed +1, Prophetic vision +2, Compounding problems +1, Heart attack / short circuit +1); Stress (Nervous +1; Jumpy +1 and +2 to every Close crewmember; Adrenaline rush -1d5 and Catatonic -1d10, never below Minimum Stress; Rage +1 to every crewmember); Maximum Wounds -1 (Heart attack / short circuit; if the character is then at Maximum Wounds, a hidden Death Save is rolled: that part is this app's reading of "on reaching Maximum Wounds: Death Save", not printed on the Panic Table, and the log says so); and Retire, which sets the character to Retired on the Crew tab so their player rolls up a new character through the usual replacement flow (set them back to Playing there if you disagree). Compounding problems applies both of its rolls' effects. The Conditions and the timed [+] / [-] (for minutes or hours) are not tracked: the agent plays them and you apply them. The table is PANIC_TABLE in cast.js.

Panic on the player's own screen. When a player's character Panics, that player's screen panics with them for a few seconds, in a way that fits the result (Adrenaline rush sharpens and races, Nervous and Jumpy jolt, Overwhelmed floods with text, Coward's cursor flees, Frightened shows ???, Nightmares goes dark, Loss of confidence greys a skill on the sheet, Deflated drains the colour, Doomed says one line, Suspicious scrambles the others' names, Haunted whispers in static, Death wish bleeds red at the edges, Prophetic vision flashes the adversary's picture glitched (static if it has none; never its name), Catatonic freezes the input, Rage floods red, Spiraling turns the screen, Compounding problems plays its two results, Heart attack stops (an android shuts down and reboots), Retire closes the crew file). Close players only see a flash when someone goes Jumpy. It is only a show: no Stress, stat or Condition changes. With reduced motion on it is slow fades only. Switch it off under Settings, Players, show panic on the player's screen; the same tab has a Try a panic screen picker for a rehearsal. The code is public/panic.js.

The agent says yes to cool ideas but never decides whether an uncertain action works. You do.

Failing forward. Whatever you or the dice decide, the agent narrates it so the story moves on. A failure is never "nothing happens": something changes, costs something, or opens a new way. How close the roll was guides how it fails (a near miss often becomes a partial success with a complication; a bad miss doesn't work, but the situation shifts), and a failure usually gets the crew past the obstacle at a price, rather than leaving them all to try and fail at the same thing. These are guides for the agent, with two worked examples in its instructions (a gunfight in a cargo bay, and freeing a crewmate from a jammed cryopod), not hard rules.

• The agent's side: when players try something risky, like hacking a door, overriding a lockout, forcing a hatch or bluffing someone, the agent plays it up to the moment of truth and stops there. It never contradicts the players or flatly shuts an idea down.
• Your side: an ⚖ Your call card appears under the comms log with the stakes (If it works: / If it fails:, which you can edit) and three buttons: ✓ (it works), ✗ (it fails) and 🎲 (call for a roll). The agent suggests a Stat or Save and whether [+] or [−] fits. ✓ or ✗ has the agent narrate the result by the stakes and make any station changes; 🎲 opens the who-rolls-what form right in the card, under the stakes.

Rolls (under Actions) follow Mothership's rules:

• Who rolls: one character, or All, where each of them rolls. The numbers come from their sheets, and the form previews each character's target.
• What: a Stat (Strength, Speed, Intellect, Combat), a Save (Sanity, Fear, Body) or a Panic check. Optionally add one of their skills and [+] / [−]. Each character who has the skill adds their own bonus for it, from their sheet; the others roll without it.
• Only that character's terminal shows a ROLL REQUIRED box; everyone else sees who is still rolling. They roll on screen, or type in their physical dice.
• Stats and Saves: success is under Stat + Skill on d100, and a roll of 90–99 always fails, whatever the target. Criticals: doubles (00, 11 … 99): doubles that succeed are a critical success, doubles that fail a critical failure; 00 is always a critical success and 99 always a critical failure. [+] / [−]: roll twice and keep the better or worse result. Failure: +1 Stress.
• A critical failure needs a Panic check. The result says "Critical failure: Panic Check" in the log and on the players' screens, and a one-click Panic check for that character appears under the roll status in your console (it calls the roll as usual). With no Warden, the app calls it by itself.
• Panic check: d20 against current Stress. Above it, they keep their cool. Equal or under, they Panic: the log names the Panic Table result; the app applies what it can (see the panic table below) and you apply the rest. [+] / [−] keep the higher or lower die. No automatic Stress.
• Nobody playing a character, or someone slow to roll? Roll for them rolls from the console. Stop waiting goes on with the rolls already made.
• Each result appears on everyone's screen and in your console. When everyone has rolled, the agent narrates what happens (with no AI key, you narrate it with Speak). The agent never mentions dice or stats in-world.

Combat

Violence follows Mothership 1e's Player's Survival Guide: very dangerous, and there is no initiative. The Warden describes the threat, every player says what they do, and everything resolves together (checks and saves first, then Damage and Wounds). The agent is told to avoid fights, to resolve them that way, and not to invent damage numbers: the app rolls them.

• Attacks. A crew member's attack is a Combat Check (you or the dice roll it as usual). After a success, Actions → Combat → Roll attack and apply damage (crew member, weapon, adversary) rolls the weapon's damage and takes it off the adversary; in Auto mode the agent does the same in its reply, and only right after that character's successful Combat check. Weapons come from the characters' items, matched by name ("Combat shotgun (registered to MARY)" is a Combat Shotgun); the list is the guide's, with its damage dice, wound type and Anti-Armor. Give the range (Adjacent, Close, Long, Extreme) on the attack form (the agent's crew_attacks carry it too, and a Combat roll called with a range passes it on): the Combat Shotgun does 1d10 instead of 4d10 at Long Range or further. The Smart Rifle's "[-] at Close" is applied to the Combat check, not the damage: choose the weapon and range when you call the Combat roll and the character rolls at [-] (this reading of where the [-] applies is the app's; the Guide's table only prints "[-] at Close"). The riders the guide prints for the Flamethrower (Body Save [-] or set on fire), Foam Gun (Body Save or stuck), Frag Grenade (hits everything Adjacent to the target), Laser Cutter (1 round to recharge), Rigging Gun (another 2d10 Damage when the bolt is removed), Stun Baton (Body Save or stunned 1 round) and Tranq Pistol (Body Save or unconscious 1d10 rounds) are printed under the hit in the log, so you and the agent apply them; the app does not roll those Saves or splash the grenade itself. With no weapon a character is Unarmed: Strength divided by 10, rounded down, Blunt Force. When an adversary or a person attacks, the agent (or you, with the same form) names the attacker, its attack and the target; the app rolls the attacker's Combat (d100 under it, 90-99 always fails) and, on a hit, the attack's damage. In Review mode the agent's attacks are listed on the draft card (they can't be unticked) and rolled when you send it. Harm that isn't an attack (a fall, an explosion) is still the agent's crew_changes, and goes through the same Damage rules, except that armor doesn't apply to it (an interpretation: the guide's armor rule is written for weapons).
• Armor. Every character has armor on their sheet: Standard Crew Attire (AP 1), Vaccsuit (3), Hazard Suit (5), Standard Battle Dress (7) or Advanced Battle Dress (10, DR 3), taken from their items (the best one) or crew attire. Damage under the armor's AP is ignored. Damage at or over AP destroys the armor and the rest (damage minus AP) goes through. Anti-Armor weapons ignore the armor and destroy it. DR always reduces damage first, even with destroyed armor and against Anti-Armor. Destroyed armor stays marked until you press Mark repaired (Crew tab); the armor's name, AP and DR are editable there. Cover isn't tracked.

These are readings, not printed rules: a hit that takes a character at Maximum Wounds down to 0 Health calls a new Death Save (house rule: the PSG gives Wounds only up to the maximum; a Death Save already waiting is not rolled again), the [+]/[−] on the Wounds Table, the Death Save countdown for Lethal Injuries, armor not applying to the agent's non-attack harm, the d10 for damage dice (1-10) against the d10 on tables (0-9), and an attack's Wounds Table roll for Bleeding damage (it uses the Bleeding column).

Resources

Ammunition, air, food, medicine and fuel. What is a Mothership 1e rule (Player's Survival Guide, PSG) and what is a campaign house rule is marked in the UI and here.

Mothership rules (PSG)

• Ammunition. Each firearm has shots per magazine (Combat Shotgun 4, Revolver 6, Pulse Rifle 5, and so on, the guide's list). The rounds in the loaded magazine are tracked per character and weapon; each attack with a firearm spends 1 shot, and the roll in the log says how many are left. At 0 the attack is refused ("out of shots") until the character reloads: Reload on the Crew tab (or reloads from the agent) is an action that swaps in a spare magazine. Spare magazines are items, "Ammo (combat shotgun) x2", which stack. Ammo costs 50cr a magazine. The agent sees every character's rounds and spares each turn; an agent attack on an empty weapon is refused and its Combat check stays unspent. Weapons with no shots (melee) never run dry. A Frag Grenade or Rigging Gun has 1 shot, so it is "reloaded" from a magazine like any other.
• Oxygen. The rig's life support is normally online and not tracked. Set the rig's rig.life_support to OFFLINE (the Warden by clicking the value on the map, or the agent with a station change) and the PSG supply procedure runs for everyone aboard the rig: 1d10 x the ship's maximum crew (4), less the breathing crew every 24 hours, [-] and then Body Saves or Death Saves, as under Hazards. It is the same oxygen hazard, listed as "The whole rig". Suits: vaccsuit 12 hours, hazard suit 1 hour, advanced battle dress 1 hour; an oxygen tank (50cr) gives up to 12 hours, 4 under strain. While a character relies on their own air, their sheet shows the hours left ("OWN AIR (oxygen tank): 9 hours left"). Oxygen tank used up (Conditions menu) discards a tank and, if they carry another, starts it fresh.
• Food and water. Only tracked when supplies are cut off: tick Rationing under Rounds and hazards (or when a story says so). From then on every hour of Pass time adds to hunger and the PSG penalties apply (after 24 hours without food, [-] on all rolls; the water minimum is the existing toggle). Has eaten then spends one ration (MRE) from the rig's stores. In a campaign, with Rationing off, nobody gets hungry; outside a campaign hunger is always tracked, as before.
• Medicine. First aid kits and stimpaks are items. A stimpak used from the Conditions menu, or by the agent as an item_changes entry with action "use", takes the item and applies the PSG effect: -1 Stress (not below Minimum Stress), +1d10 Health (up to the maximum), [+] on all rolls for 1d10 minutes, and it cures cryosickness. A dose after the first within 24 hours rolls 1d10 (read 0-9, like the Death Save die): rolling under the number of doses in the past 24 hours (this one included; two doses means 0 or 1) is a Death Save. The doses and the [+] are on the sheet and count down on rounds and hours. A First Aid Kit stops Bleeding.

Campaign house rules (Mothership 1e does not have these; its own fuel figure, about 1 per month, is for whole-system travel, and our lanes are short hauls)

• Fuel. The rig carries fuel in units; the tank holds 10 (LONG HAUL MARY starts full). A lane costs 1 unit per started 3 days of its length: 3 days = 1, 4 = 2, 9 = 3. In a transit story the lane's fuel is burned when the story starts (once; Rebuild does not charge again). With 0 fuel the rig is stranded: the agent is told and it is a story hook.
• Stores. Parts, explosives, flares and rations (MREs) are simple counts on the rig. Starting values are in campaigns/rim-haulers.js (ship.resources).
• Between stories. The rig's fuel and stores live in the campaign. Every story starts with them as the station's rig.* values (rig.fuel_units, rig.parts, rig.explosives, rig.flares, rig.rations, rig.life_support); the agent and the Warden change them with station changes, Retcon undoes that, and Finish story reads them back. The characters' ammunition, items and doses ride along on their sheets as before. The rig's fuel and stores appear in the player header on MARY's own terminals, in the campaign status line and on the Overview.
• Travel. Campaign → Overview → The rig: Travel along a lane from where the rig is. It costs the lane's fuel, moves the rig, and starts no story. It is refused without enough fuel, or while a story is being played.
• Resupply. At the port the rig is at: buy fuel, ammo for a chosen firearm, first aid kits, stimpaks, MREs (a pack of 7 goes to the rig's rations) and oxygen tanks. The goods go straight onto the rig and the chosen character's sheet. Prices are the PSG price x the port class (house rule: X x2, C x1.25, B x1, A x1) x the faction's price factor from Faction standing. Port classes: Port Gallow A, Tollgate C, Halfway House C, Cinder's Reach B, Saint Brigid's C, the Boneyard C, Lantern X, Terminus Relay C. A faction that will not trade, will not sell. The PSG has no fuel price: it defaults to 500cr a unit (house rule), which you can change; the port multiplier applies. The price is taken from the account you pick under Paid from, the rig account or a character (see Pay, debt and union dues); Resupply is refused if that account cannot pay the whole price.
• Starting magazines. Kofi has 2 spare shotgun magazines and Wanda 1 for her revolver (a house loadout).

Ship-to-ship combat

Ship fights in a campaign (HOT LOAD and BLOCKADE RUN, and any story the Warden or the agent turns into one). The framing comes from the Shipbreaker's Toolkit, via a secondary summary (Justin Alexander's Mothership cheat sheet), not the book, so it is implemented as that summary states it and nothing more. Everything the summary leaves open is a house rule, labelled "house rule" in the UI and below.

From the Shipbreaker's Toolkit (via a summary)

• Ship stats and checks. Thrusters, Battle and Systems are rolled like a Stat (d100 under it, 90-99 always fails, doubles are criticals), by one crew member who adds one relevant Skill bonus. They are rolled on the players' screens (a "ship" check type that targets the ship's stat instead of the character's). A failure gives all crew +1 Stress; a Critical Failure also gives all crew a Panic Check (offered to the Warden like other Panic Checks). Ships also have Hull and a running MDMG total. Classes: 0 Shuttlecraft, I Light Commercial, II Medium Commercial, III Heavy Commercial, IV Light Military, V Medium Military.
• Ranges. Detection (railguns only), Firing (all weapons), Contact (boarding). The Warden can also move the band by hand.
• A round, in order. (1) Movement: each side secretly picks Maintain Course, Evade or Pursue. Maintain spends no fuel and the other side automatically succeeds. Evade needs at least 3 fuel at Contact, 2 at Firing, 1 at Detection. Both sides roll Thrusters; whoever spent more fuel has [+]. Success against failure moves the band one step (out for an evader, in for a pursuer); a Critical Success moves it even against a success; a Critical Failure lets the other side move it even if they failed; a tie changes nothing. (2) Attack: every ship within Firing range makes a Battle check. Critical Failure: +2 MDMG to itself; failure: +1; success: deals damage; Critical Success: double. An unarmed ship automatically fails. Hull is subtracted from the damage; at or above Hull, Hull drops by 1 after the hit; what gets past Hull is added to MDMG and the effect for the new total applies. (3) Morale: 1d10 for each enemy that took MDMG this round; under its MDMG total it may hail, offering a ceasefire or to talk (the agent voices it).
• MDMG effects, by total. 1 emergency fuel leak (every fuel spend costs +1), 2 weapons offline (Battle checks automatically fail), 3 navigation offline (no Thrusters checks), 4 fire on deck (the burning sections become a toxic and highly corrosive atmosphere), 5 hull breach (everyone aboard: Body Save or 1 Wound, Fire & Explosives; a Critical Failure is sucked into space), 6 life support offline (oxygen 1d10 x the max crew of 4, as in Hazards), 7 radiation leak (Radiation Level +1 every 2d10 minutes), 8 dead in the water (emergency power only), 9 or more abandon ship (destroyed in 1d10 minutes, a clock on every screen). On the rig these run through the Hazards (fire, breach, oxygen, radiation), the station values and the Clocks.
• Unwinnable fights. Against a ship one class lower, [+] on all Battle checks. A ship two or more classes above the rig can't be beaten head-on: the panel says so, the crew make no Battle checks, and the options are flight, surrender or a trick.

House rules (the summary has no numbers or tables for these)

• Ship numbers, on the same 1-99 scale as character stats (campaigns/rim-haulers.js): LONG HAUL MARY Class II freighter, Thrusters 35, Battle 0 and unarmed (her Battle checks automatically fail unless the crew fit a weapon, which the Warden does under Campaign → Overview and gives a Battle stat), Systems 40, Hull 3. THE RED TIDE: Class I raider, Thrusters 50, Battle 45, Systems 35, Hull 2, an autocannon (Firing). WRIT OF SEIZURE: Class II patrol class, Thrusters 45, Battle 50, Systems 50, Hull 4, a railgun (Detection) and point-defence (Firing); it broadcasts a transponder, the Red Tide does not. Stories 12 and 20 have no ship written (the Warden can start a custom ship with their own numbers).
• A hit deals 1d5 before Hull. 1 rules "fuel" = 1 rig fuel unit (the rig's units come from the Resources section; the fuel leak adds 1 to a spend).
• Maintenance Issues. After a fight in which the rig took MDMG, a failed Systems check rolls one issue (two on a Critical Failure) on a 6-entry table the app writes: coolant leak, sensor ghosting, stuck airlock, drive misfire, dead cargo clamp, CB down. A minor repair (2d10 days) fixes one.
• Resupply costs 1 kcr per weapon at a port. Patch job: a port removes 1 MDMG for 20 kcr, and the rig keeps a Maintenance Issue (major repairs at 1d5 mcr x class are the book's price and ruinous for a trucker). The Warden takes the credits.
• Fire or hold fire. Each round each ship chooses (the players for the rig, the Warden or the agent's enemy_fire for the enemy). Only a ship that fires makes a Battle check and suffers its results (+1 or +2 MDMG to itself, and for the rig all-crew Stress or Panic Checks). An armed ship fires by default; an unarmed one holds fire, so MARY doesn't hurt herself or stress the crew by being unarmed. An unarmed ship may still choose Fire (a ram or a bluff): that is an automatic failure with all its consequences.
• Distress modifiers: the Rim counts as an outer system (+1 step) and the Dark Lane as isolated (+2).
• How effects 4-9 land. The summary says "the burning sections"; the app sets a toxic atmosphere in one rig room and a corrosive atmosphere (level 10) in another, since a room holds one hazard. The radiation leak starts in the Engine Room. "Dead in the water" sets the reactor, drive, lights and cargo camera to emergency/offline station values. Only the effect for the ship's current MDMG total applies (a leak at 1, weapons offline at 2, navigation offline at 3 and so on), so the all-systems-offline totals (8 and up) also take weapons and navigation. A ship with no Thrusters check (navigation offline) counts as having failed it for the comparison and takes no Stress.

Using it. Actions → Ship fight (campaign only): start a fight from the story's ship list (or a custom ship) at a range, have each player pick a station on their screen (Pilot, Gunner, Engineer: Pilot rolls Thrusters with Piloting, Gunner Battle with Firearms, Engineer Systems; the Warden can pick another skill), the Pilot sets the rig's course and fuel, and set the enemy's move (or press Agent picks). Resolve movement and Resolve attack and morale then run the phases. Retcon undoes the last step. Board (Contact) reveals the boarders and hands over to the crew combat above. End fight records what the weapons owe and calls the Systems check. Players see a compact readout (range, the rig's Hull and MDMG, and the enemy as far as the range lets them identify it: its transponder at Detection, class and type at Firing, status at Contact). The agent gets the fight's state every turn and a ship_fight reply field (start, end, enemy_move, fuel); in Review mode the move shows on the draft card. The rig's Hull, MDMG, issues and what it owes in resupply carry between stories; repairs, patch jobs, resupply and fitting a weapon are under Campaign → Overview.

Screen effects from the agent

Besides you, the agent can trigger the electronic effects: alarm, red alert, glitch, static, blackout, lockout and banner (blood, goo, the crack and ice stay yours). It can time them between lines of dialogue:

• On a line: an effect fires the moment that line begins, after the previous line has finished appearing and being spoken. For example, static as Salk's second sentence starts.
• As a beat: an effect on its own, between lines, pauses the dialogue for its duration. A blackout always plays as a beat: the screen goes dark, then the next line comes once the lights are back.
• On the whole reply: effects can also fire as soon as the reply starts.

In Review mode each line in the draft shows its effects as ⚡ chips, which you can untick before sending. Agent may trigger screen effects turns all of this off.

Sounds

Upload your own audio in Sounds (under Actions): monster growls, attacks, screams, station ambience. Use the button or drop files on it; MP3, WAV, OGG, M4A, FLAC and WebM work, up to 10 MB each and 100 MB per session (MAX_SOUND_MB, MAX_SESSION_SOUNDS_MB).

• ▶ Once plays a sound on every player screen (an attack, a bang on the hull).
• 🔁 Loop keeps it going until you stop it (a low growl, reactor hum, dripping). Loops fade in and out, and you can change a loop's volume live under Playing.
• Each sound has its own name and volume, saved with the session. Set the volume with the slider, or type an exact percent in the box beside it. Restart story stops everything; the library stays (even through Factory reset).

Sounds play through the players' VOL control. Players who join or reload mid-scene pick up any running loops once they press a key. Files are kept under data/sounds/<CODE>/ and deleted with their session.

Built-in sounds: every story starts with seven in its library (stories saved earlier get them once): Lurking monster, Monster growling (long), Deep monster roar, Monster bite, Monster eating, Tension drone (background) and Dramatic riser. The files come from a private S3 bucket onto the server (see deploy/README.md), not from git. Removing one from a story only takes it off that story's list, and they don't count toward a session's upload limit.

The agent's sounds: while the agent may use screen effects, it's given the story's sounds by name and can put one on a line. It starts as that line starts and plays under the words, never holding them back (a blackout still does).

In audio logs: a line of its own like [SOUND: Monster bite] (any sound's name; [SFX: ...] works too) plays that sound and goes straight on to the next spoken line, so the two overlap. The transcript shows it as [ MONSTER BITE ]. A sound on the last line plays out; any others still going fade out when the recording ends. The agent knows this when it writes recordings, and the Warden can type it into a handout too.

Voices & entities

The narrator is part of every adventure: a plain, calm human voice (NARRATOR) that describes what happens around the players, like water dripping, a panel flickering, an explosion below, people moving and reacting. Its lines show as white italic scene description with no name, whatever the terminal's colour. It never speaks to the players or their characters (never "you"), never says what the characters do or feel, keeps it brief (a sentence or two, under 25 words), and is used when something happens, not on every reply. It's heard on every system (it's the room, not a machine). Switch it off under ⚙ (narrate the scene); you can still Speak as it yourself. The first time a voice that isn't a screen's computer is heard on a system (once per voice per system, again after Restart story), the narrator brings it in with one line. For comms (the intercom, broadcasts, a radio) that's where it comes from and how worn the speaker is ("A cracked speaker grille by the door spits static, then a voice."); for a creature or entity, something specific to what it is, never a speaker. The agent writes these. If it doesn't (or you Speak as the voice), the app adds a stock line for comms voices; there's no stock line for a creature or entity. As things get worse, the narrator may now and then show the speakers wearing down.

Every line on the players' screen belongs to a voice, and the agent can speak as any of them. No voice is the default: the agent answers as whoever would really respond. If the players talk to Salk, Salk answers (in person or over the intercom, see Characters below); HV-CORE answers terminal commands. A reply can mix voices, for example Dr. Salk on the intercom, then a station-wide announcement. Two voices are built in: HV-CORE (the terminal) and System Broadcast. Add any number of others under Voices, personas & settings, such as an intercom, a stranger on comms, or the thing in the vents. You can also pick one in the comms box (or Tab to it) and Speak as it yourself.

Each voice has:

• Persona: who it is, how it talks and what it knows. The agent reads every voice's persona. HV-CORE's persona is the terminal's main personality.

• On-screen style: plain text, a NAME: label, or boxed, plus an optional colour.

• Engine: Human (neural, natural-sounding: 28 US/UK male and female speakers, adjustable pace) or Synthetic (eSpeak, with pitch and speed). Human is best for intercoms and people on comms. Synthetic suits machines and monsters.

• Effects: speed/pitch, low and high cut, distortion, robot warble (ring modulation), metallic resonance, chorus, echo, reverb and radio hiss. Presets: intercom and human (human engine), and robotic, ethereal, radio, demonic, whisper and clean (synthetic).

▶ Test plays a voice on your computer only. Lines you send as a voice become part of the agent's history as that voice speaking, so it stays consistent.

Characters

The story's people (Salk, Okonkwo, Marlowe...) are listed under Characters on the Crew tab, apart from the voices. Each has a name, a human speaker voice (▶ to hear it), notes the agent reads, the room they're in now, and an optional picture.

• Where they are decides how they're heard. Someone in the same room as a player's terminal talks to them face to face: a clear voice with no speaker effects, shown as SALK: in the screen's own colour, and only on screens in that room. Anyone else comes over the intercom (INTERCOM · SALK:), with its static and effects, wherever the intercom reaches. Each card says which (in person or intercom). Heard elsewhere over (unlocked) picks the voice they come through; the intercom by default.
• The agent keeps them moving. It moves people between rooms as the story goes (someone walks in, flees, is dragged off, dies), brings in new people with a voice of their own, and adds to someone's notes when something new is true about them (hurt, infected, has the keycard); it never rewrites what's there.
• Stress and panic: each character has Stress (0–20, starting at 2), on their card. The agent raises it when frightening things happen to them, and when something truly horrifying does (a door blown open on the creature, a friend torn apart), it calls a Panic check: they roll a d20 in front of the players, with the same dice reveal as the players' own rolls. At or under their Stress, they panic: the number is looked up on the panic table (see below), so only the very stressed can roll the worst. The agent then plays it out. Panic check on a card rolls one yourself.
• How they feel about the players: each character has an attitude (this app's scale, not a Mothership rule), from Hostile (−3) through Wary, Neutral (0) and Friendly to Loyal (+3), with a short reason. Everyone starts Neutral. The agent reads it every turn and plays them by it (what they'll share, whether they help, stall or lie), and moves it, usually a step at a time, when the players clearly earn or lose their trust. You can set it too, on the card, even locked. Players never see it. Each change is noted in your log, and Retcon undoes it. You can change the room any time, even locked; the rest when unlocked.
• Pictures: click the square at the left of a card to choose one: pick any of the 102 portraits from the pack that comes with the app, Upload your own… (cropped to a small square), or No picture. It's shown to the left of what they say on the players' screens, about two lines tall: line art in the line's colour, with the screen showing through the paper. Uploads are turned into the same kind of line art (the dark parts drawn, the light parts see-through), so line drawings suit best. Face to face it's clean; over the intercom it gets static, a rolling bar and flicker. takes it off. Pictures are kept under and deleted with their session. KESTREL-9's people and crew come with pictures from that pack (older saved KESTREL-9 stories get them too, for anyone who has none). The pack lives in (listed in ), from the by Victor J Merino, under , so the players' screens credit it in the bottom-right corner of the start-up screen (not during play, and not when the story uses none of them). That licence rules out commercial use.

Other voices (the tug's computer, a radio) speak with one voice each.

Adversaries

The story's threats (the creature, the thing in the walls) are under Adversaries on the Crew tab, below Characters. KESTREL-9's is THE COLD (its picture: Of the Void by thienbao on DeviantArt, linked, not copied).

• ??? until they see it. Until the players have seen an adversary, its lines show as ???: and nobody in the story names it. When they see it, the agent marks the line where it happens: as that line plays, its picture goes up (if it has one) with the sting, and its lines show its name from then on (each line keeps the name it was said under); you can tick revealed yourself too (or untick it). The log shows its true name, with "seen as ???" while it's hidden. Retcon undoes a reveal.
• What it is: its name, notes the agent reads (what it is, what it wants, how it acts and speaks), how it sounds (a preset, with ▶ to hear it), and its colour. Its finer sound settings and which systems hear it are with the other voices (Story tab and Connections).
• A picture: click the square on its card to upload one (kept as a picture, up to 720 px), or paste a link to one on the web (it loads from there; nothing is copied). THE COLD's is a link to Of the Void by thienbao, credited. Show picture to players puts it up on every player's screen, tinted to their terminal's colour, in the panel beside the terminal (so the dialogue stays in view; full screen on phones); showing it also reveals it. A click, Esc or CLOSE puts it away. Add a picture credit (the artist, a link) and it's shown under the picture.
• The Story Builder writes a story's adversaries too.

Speech is generated on the server, with no API key and no per-use cost:

• Human voices use Kokoro (the kokoro-js package). Its model (about 330 MB at full precision) downloads once and is cached in node_modules. Generation begins the moment a line is sent, while the text types out, and the model loads at server start whenever a human voice exists. If the model can't load, those voices fall back to eSpeak.
• Expressive voices use Kitten TTS 2 (pick Expressive (Kitten TTS 2) as a voice's engine). The agent acts their lines with delivery cues: a leading emotion ([nervous], [stern], [sad]...), vocal events (<sigh>, <gasp>, <laugh>...) and emphasis ((((never)))). The cues are spoken, never shown; a line the Warden types can use them too. Kitten is Python, so it runs on the server only, in a sidecar (scripts/kitten_tts.py): install it with pip install kittenml soundfile, and set KITTEN_PYTHON to that Python if it isn't python on the PATH (KITTEN_WEIGHTS=emb4 for the smaller 506 MB download). The model (about 1 GB, 6 GB RAM, or a CUDA GPU) downloads on first use; until it's loaded, or if it can't start, those voices use eSpeak. Cast members keep their Kokoro voices.
• Synthetic voices use eSpeak (the mespeak package) and are instant. The player's browser applies the effects. Speech starts once a player presses a key on the boot screen, because browsers block sound until then. The DM preview is always silent.

Spoken text is revealed in step with the voice: each line appears as it starts being said, and the next waits until the voice has finished. Terminals that are muted, or have sound off, just type the text out.

A blackout cuts off the voice that's speaking instantly. Queued lines wait for the lights to come back, then carry on.

Speed:

• The human-voice model runs at full precision (TTS_DTYPE=fp32) on all CPU cores, which is about 4× faster on CPUs than the 8-bit model.
• It loads and warms up when the server starts.
• Audio is generated as soon as a line exists. In Review mode that's while you read the draft, so an unedited line plays the moment you send it.
• Clips are cached in memory, and on disk under data/tts-cache (capped by TTS_CACHE_MB, default 200), so repeated lines are instant.
• If RAM is tight, TTS_DTYPE=q8 uses about 300 MB less, but is slower.

Players have a volume control in the top-right corner: a ten-segment meter you can click, drag, scroll or use the arrow keys on. Click VOL to mute. It's remembered per device and controls all sound, both effects and voices.

Sessions save to data/sessions/, so they survive a restart. API keys are the exception: they're never saved.
