YE BOOKE OF MONSTRES contains dozens of new races and individual creatures for use with the Call of Cfhulhu roleplaying game. Included here are the following Outer Gods, Elder Gods, Great Old Ones, Great Ones, Avatars, Servitor Races, Independent Races, Fabulous Creatures, and Unique Entities. These monstrous creations have been collected from fiction spanning over seventy years and from over ten years of favorite Call of Cfhulhu scenarios. The darkly imaginative work of a diverse group of authors is represented here. Where possible each entry begins with a quote describing the monster or entity. Where much about the creature is known, there may be an additional description. If discussing a god, Great One, or Great Old One, notice of any human cult comes next. Further notes discuss habit, habitat, or attack.
