Who we are

Worlds Beyond Number is a new narrative-play, audio fiction multiverse created by and starring titans of tabletop Brennan Lee Mulligan, Erika Ishii, Aabria Iyengar, and Lou Wilson.

Worlds Beyond Number is an independent, creator-owned podcast about playing games and making up stories with your friends. Across genres, across worlds, from immersive, years-long cinematic epics to wild, chaotic one-shots, the possibilities are endless.

This includes our flagship story told over 2 and a half years - the Wizard the Witch and the Wild One - whose full first book, told in four arcs, is available wherever you get your podcasts. Plus, our Patreon subscribers get access to exclusive behind the scene Fireside Chats as well as other stories like The Children’s Adventure, A Space Cram, Class Action, and other shenaniganery.
