From the introduction: The Caves of Valesh Kanos is a one-shot story session designed to be played with the Tales of Arcana Roleplaying Card Game, though it could be adapted for play with other RPG systems. It is designed for one Story Master (SM) to narrate and three Players, with the overall session lasting 1.5–2.5 hours. Players will randomly generate their characters. Only the SM should view this Story Guide and should read through it before the session begins. Occasionally, [characters] will receive tips from two natives of Arcana: Manitous, the god of reality and Glytch, a fablead (story nymph). Glytch is very helpful, but it might be best to just ignore Manitous.
