From publisher blurb:
Adventurers fight vampires, either as dime-a-dozen villains or masterminds at the center of sinister plots. But what is it like to be a vampire in a fantasy world, to move through a world where your prey can be as dangerous and cunning as you, and lurks in the shadows which you call home? Transform your campaign with this supplement, compatible with Pathfinder RPG, and explore what it means to be a vampire - to struggle for survival, secrecy, and power in a world that would destroy you if it knew you. Expand on existing campaigns with new content that brings out undead themes in even living characters as well!
