Pathfinder Campaign Setting: The First World, Realm of the Fey by James L. Sutter
Explore the legendary realm of the fey, where reality reinvents itself and strange creatures peddle stranger wares to the unwary. Learn about the godlike Eldest who rule the First World and how to navigate their fairy courts. Delve for treasures in adventure locations too bizarre for the mortal realm, using new gear, spells, and other rules specifically designed to keep you alive in a world where death is seen as a game. Uncover the true origins of gnomes and other secret histories, battle a horde of new fey monsters, and harness the power of the fairy lords yourself with the feysworn prestige class!
