Catalyst Cabinet of Curiosities is a gameroom and magic item workshop for adults in Petaluma (Sonoma County) California . We host role playing games such as Dungeons and Dragons (D&D, DnD) at an event we call Drinks and Dragons, and host parties to make props (magical Items) for game play which we also sell. Our mascot is Captain Capra Cornelius.

Welcome travelers, to 

an immersive gameroom for adults


I am Captain Capra Cornelius, curator of this establishment. Together with my trusted partner, Jessica, we are proud to share our collection of curious ARTifacts from across the planes and throughout time to help the denizens of Petaluma California discover the magic in the mundane. Here, with your band of adventurers, embark on your own quest that combines tabletop RPGs like Dungeons and Dragons, with a truly immersive gaming environment. Solve puzzles while interacting with my collection of relics, rarities, expansive maps, stunning terrain, minis and other curiosities.

We hope you enjoy Catalyst as a home away from home!
