The first campaign for Sandy Petersen's Cthulhu Mythos! The Isle of the Ghouls is a complete campaign inspired by the Mythos to take your players' characters from their first adventure to the upper echelons of heroic fantasy. The four acts of the campaign are subdivided into episodes for you and your players to enjoy. Each chapter builds on the previous one to tell an immersive story that grows in difficulty, complexity, and scope. Each episode is designed to be completed over the course of a session and culminates with the characters leveling up. Travel to a lost world and discover horrors forgotten by time! A copy of Sandy Petersen's Cthulhu Mythos is required to play.
