Lovecraftian Horror comes in many guises.
As the adventurers continue on their path through the nightmarish lands of forgotten times and places, they maintain their vigilance against the creatures that either twisted this place or were twisted by it. There are monsters they have never seen but have heard about in the tales of those who are mad. Every sound is a warning, every shadow a nemesis. Never knowing what to expect, they move forward with desperate hopes of seeing a new day.
Sandy Petersen Games has released a collection of monsters designed for and from their Cthulhu Mythos Saga settings. Nightmares: A Saga Bestiary I is a collection of monsters developed from the first three Sagas: Ghoul Island, Yig Snake Granddaddy, and Dark Worlds.
