A collection of 31 Lovecraftian monsters, written for Trail of Cthulhu but usable in any Mythos horror game. Featuring nine all-new creatures that have never taken stat-block form in any game before! Lovecraft created his "shadowy congeners" because the stories of vampires and werewolves had become too familiar and formulaic to evoke true horror. Almost a century later, his own monstrous races have likewise begun to seem like comfortable story furniture rather than unnerving signals that the world is horrible and wrong.

In Hideous Creatures: A Bestiary of the Cthulhu Mythos, we present a comprehensive look at Lovecraft's hideous creatures, from as many angles as we can. Our goal is contradiction, surprise, and most especially the uncanny: the recognition of something familiar as something weird. Creatures are not just antagonists to fight or flee from; they are entire adventures by themselves, leaving physical traces, occult clues and madness in their eldritch wake.

Hideous Creatures: A Bestiary of the Cthulhu Mythos is the Trail of Cthulhu bestiary written by Mythos giant Kenneth Hite and fellow experts Gareth Ryder-Hanrahan, Becky Annison, Helen Gould and Ruth Tillman, in the tradition of the award-winning Book of Unremitting Horror and the 13th Age Bestiary.
