Mothership RPG campaign notes

A minimalist sci-fi horror RPG about frightened crews, fragile plans, failing infrastructure, and the terrible things waiting in ships, stations, and dead places.

RealmBinder turns your table's rough notes or recordings into a shared record of the campaign: session recaps, characters, places and quests. Set the campaign to Mothership RPG and it knows the kind of story you are telling.

3 Mothership RPG campaign frames

Choose a frame when you set up the campaign, or keep just the system. The frame picks the covers you start from, sets the look of the art, and tells RealmBinder the setting when it tidies your notes.

What changes in a Mothership RPG campaign

Notes that keep the right tone

When RealmBinder rewrites a session or the Chronicler asks you about one, it is told what a Mothership RPG story sounds like. It uses that for tone only: what your table wrote down always wins.

Tone
Panicked, minimal, claustrophobic, and survival-focused.
Focus
Emergency problem-solving, mounting stress, environmental dread, and encounters with forces that are poorly understood and badly timed.

Beside your other tools

RealmBinder isn't a character sheet, a rules reference or a virtual tabletop. Keep playing Mothership RPG the way you do and link the character sheet you already use.

Characters in the game's own words

Player character profiles ask for a archetype, species and background, the terms Mothership RPG players already use.
