From publisher blurb:
Bats is a Bestiary article.
Bats are feared by many, in part because they have long been associated with witchcraft, darkness, and evil. This bestiary article describes the habitat and physical attributes of Hârnic bats, with full HârnMaster stats.
The article also gives full information on rabies, "The Wreaker's Madness," and how to reflect its effects in HârnMaster.
