From publisher blurb:
The folklore of almost all Hârnic and Lythian cultures includes tales of lycanthropes and their origins. Lycanthropes are people who have been cursed to involuntarily alter their form to that of a half-human, half-animal creature, typically during the night of a full moon. Although werewolves are the most common type of lycanthrope, the accursed may take on other forms, including that of a werebear or werecat.
Lycanthropes is a bestiary article that includes full descriptions and HârnMaster stats for the werewolf, werebear, and werecat. It describes how lycanthropy is spread and possible remedies for it, as well as how the various Hârnic religions view the affliction. HârnMaster rules are given for GMs to generate lycanthropes, either as player characters or NPCs.
