A century ago, the nation of Sarkoris was murdered. Today, the fallen nation is a horrific, post-apocalyptic nightmare cloven by a vast canyon that connects Golarion to the demon-haunted reaches of the Abyss. This rift is known as the Worldwound, and through it the demonic hordes pour forth, set on defiling the world of mortals and claiming it for their own. Though the demons have so far been held back at the borders by barbarians and crusaders alike, the region that was once Sarkoris remains a fiendish beachhead on the mortal realm. Worse, the Worldwound itself is slowly growing—and if something isn’t done to halt this blight, the demons it spawns might one day swallow all of Golarion!
