The epic conclusion of the Ghoul Island Saga. After regrouping, the characters are pulled into the Dreamlands to find the tools necessary to defeat Ghatanothoa's influence.
The return to Farzeen pits them against the Deep Ones and beings summoned from the Void. Former allies prove their true colors and in the end, the power of a Goddess must be summoned to save the day.
Certain spells and monsters in this adventure come from Sandy Petersen's Cthulhu Mythos. While it is possible to play the adventure without that material, some adjustment will be required. SPCM also contains the core mechanics of a Cthulhu Mythos game, including special skills, languages, races, and classes, rules for Dread and Insanity, and a full bestiary. It's very much recommended, to get full enjoyment out of any Cthulhu Mythos adventure.
