From publisher blurb: Made for use with the Pathfinder Roleplaying Game as well as the Spheres of Power and Spheres of Might systems, the wraith is a dark power given form. Whether through training in forbidden arts or their own ghost-like nature, the wraith has the ability to enter into objects, animals, allies, or opponents, consuming their will and taking control. Wraiths are the stuff of nightmares, spreading fear wherever they go and a score of broken hosts in their wake. Complete with archetypes, two Npcs, and even options for other classes, the wraith is a perfect option for unorthodox players, horror games, or just a Halloween-themed adventure. Wills were meant to be broken.
