Murky Grey Matter

Murky Grey Matter was formed by a few friends to develop high-quality, engaging games and supplements that challenge players, promote critical thinking, support game or dungeon masters, and create fun-filled memories.
With decades of experience creating immersive world systems, running campaigns in a wide variety of genres and systems, as well as extensive player experience, we have decided to produce games that fit overlooked niches in the tabletop world, and add a fresh perspective to existing frameworks.
