“The Most Merciful Thing in the World is the Inability of the Human Mind to Correlate all its Contents.” H.P. Lovecraft coined the term "Yog-Sothothery" to refer to the fictional myth cycle he invented for his tales -- what subsequently became known as the "Cthulhu Mythos" (after other writers had added their own original horrors to sit beside Lovecraft's). This book is a resource that seeks to pare away the later inventions and present the purely Lovecraft inventions, compiled with game statistics that make it easy to drop them into roleplaying scenarios, campaigns, and game settings. HPL's many Unnatural Entities, Weird Rituals, Cults, Artifacts, Tomes, and Places in this book can be considered a kind of “grab bag” of elements you can use to infuse any game world with a Lovecraftian flavor.
