Path of the Hellknight
This Pathfinder campaign supplement explores the Hellknights, merciless enforcers devoted to absolute law rather than good or evil. It details their history, philosophies, relationship with the legions of Hell, and the requirements for joining their orders. The book describes seven major Hellknight orders and their brutal rites, along with feats, spells, equipment, and magical disciplines associated with armored knights and masked signifers. It also includes new class options, including the Ennead Star cavalier order and additional choices for the Hellknight prestige class.
