Hideous Creatures
A sourcebook for Trail of Cthulhu campaigns, this book presents a bestiary of Lovecraftian creatures through conflicting accounts, variant abilities, and alternate interpretations. Each entry connects an entity to myths, historical events, and folk tales, while providing physical clues, occult evidence, adventure seeds, and handouts for investigators to uncover. The creatures are presented as mysteries and sources of madness as well as threats to fight or escape.
