A group of heroes, guided by mystic visions, descends into the maw of Perdition's Mouth, a system of caverns that twists and turns beneath the earth. Within the caverns, a corrupt cult has gathered, where it hopes to summon a terrible demon to the surface.
Perdition's Mouth is a different type of fantasy co-op dungeon crawl for 1-6 players. Each player has a unique deck of cards that they use, and all actions have to be carefully planned out on a rondel. Combat is diceless and easily resolved.
