From publisher blurb: Presented here are three hybrid races, beings that cannot help but exhibit the dark side of their heritage. Beast-Kin are savage beings that are as much animal as human; Half-Ghouls are the spawn of humans and carrion-devouring undead; and Vardogers are a hybrid race of lesser shape-shifters descended from Doppelgangers. This mini-sourcebook has been specifically designed for use with the Pathfinder Roleplaying Game but can be used with any OGL-based game pretty much as-is and easily adapted to any related or successor systems.
