Hideous Creatures: Serpent Folk

This Mythos supplement examines the serpent folk, tracing their legendary history and presenting alternate interpretations of their origins, nature, and connection to Yig. It explores their role in ancient Valusia, hidden cults, and the darker corners of human history. Keepers receive clues for Investigators to follow, along with scenario seeds and story ideas involving these shape-changing, venomous creatures. The supplement can be used as a stand-alone source of material for Trail of Cthulhu.
