It is the Age of Cthulhu, and the cold tentacles of primeval madness reach across the globe. In this compilation of three adventure modules, the investigators journey to Peru, Sumatra, and Tibet in a desperate quest to uncover mysteries that imperil the world. Incan ruins, erupting volcanoes, and madness at the top of the world await those brave enough to unravel the long reach of evil.

This all-new adventure module uses the Chaosium BRP system and is officially licensed for use with Call of Cthulhu.
