While many legendary heroes of Golarion fit easily into the core classes of the Pathfinder Roleplaying Game—the sword-swinging fighters, fireball-flinging wizards, backstabbing rogues, and others—there are some who specialize in unique styles and techniques, perfectly customizing themselves for their roles. For these characters, there are prestige classes. From the undead-hunting Knights of Ozem to the revolutionary Gray Gardeners of Galt, this book collects 30 of the most prominent faiths and factions from around the Inner Sea and transforms them into prestige classes designed to help you take advantage of the tricks and tactics of some of Golarion’s most famous (and infamous) groups, all while rooting your character firmly in the lore and societies of the Pathfinder campaign setting.
