Call of Cthulhu campaign notes
Investigators confront truths humanity was not built to process, usually in a slow collapse from curiosity into dread. The classic frame is 1920s cosmic horror, though modern-era campaigns are also common.
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 Call of Cthulhu and it knows the kind of story you are telling.
4 Call of Cthulhu 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 Call of Cthulhu campaign
Notes that keep the right tone
When RealmBinder rewrites a session or the Chronicler asks you about one, it is told what a Call of Cthulhu story sounds like. It uses that for tone only: what your table wrote down always wins.
- Tone
- Dreadful, investigative, restrained, and existentially unnerving.
- Focus
- Clues, obsession, sanity, hidden histories, and the cost of knowledge.
Beside your other tools
RealmBinder isn't a character sheet, a rules reference or a virtual tabletop. Keep playing Call of Cthulhu 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 role, species and background, the terms Call of Cthulhu players already use.
