With fabulous magical abilities at their command, the heroes ascend to the sanctuary of the dead god Aroden high in the Kortos Mounts. Their path is barred both by epic trials Aroden placed to test visitors and by powerful foes protecting the wicked prophet Sarvel Ever-Hunger. The race is on as Sarvel labors to unlock Aroden's extinction curse, a ritual to wipe out life on the Starstone Isles! The Extinction Curse Adventure Path concludes with "The Apocalypse Prophet," an adventure for 18th- to 20th-level characters.
