Homebrew Systems

I like to design homebrew TRPG systems, sometimes for specific settings or campaigns, sometimes to evoke a particular experience in those that use it.

Here you can find several of these systems, though some are still in development.

Cortex is a mystery TRPG system where each player controls one part of a detective's mind. It's designed both to help players roleplay as well as give the DM writing prompts for a mystery.

Morbus Sanctum is a TRPG system based on humorism, where you gain powers the further your infection with the plague grows.

Sunless City is a TRPG system made for the Fallen London universe. It's designed to be accessible and to encourage players to make a richly flavoured characters that make meaningful choices.
