This rift is known as the Worldwound, and through it, the demon horde has infested an entire region. While the demon armies have been held in check by barbarians and crusaders alike, the region within that was once Sarkoris is now ruled by fiends. Worse, the Worldwound itself is slowly growing -- if something isn't done to halt this blight, it and the demons it spawns may one day swallow all of Golarion! This Pathfinder sourcebook explores the demon-blighted land of the Worldwound (site of the new Wrath of the Righteous Adventure Path) in great detail. Ruined cities (such as the shattered capital city of Iz, the frozen city of Dyinglight, and the river city of Undarin), key historical sites (like the Circle of the Hierophants -- birthplace of the druidic sect known as the Green Faith), and more are presented, along with an exhaustive examination of the strange and otherworldly hazards of the region. The book also includes several adventure sites ready for exploration, along with a few locations like the holdout town of Gundrun, which can serve heroes as (relatively) safe harbor in a deadly land. Finally, an extensive bestiary presents more than a dozen new monsters and demons and enemy NPCs along with two new monster templates, ensuring your PCs will never lack for foes in this devastated realm.

Can the heroes escape with their brains intact, or will they become merely the latest addition to an otherworldly collection?
