For more than a hundred years, the demon-infested Worldwound has warred against humanity, its Abyssal armies clashing with crusaders, barbarians, mercenaries, and heroes along the border of lost Sarkoris. But when one of the magical wardstones that helps hedge the demons into their savage realm is sabotaged, the crusader city of Kenabres is attacked and devastated by the demonic hordes. Can a small band of heroes destined for mythic greatness survive long enough to hold back the forces of chaos and evil until help arrives, or will they become the latest in a long line of victims slaughtered by Deskari, the demon lord of the Locust Host? This volume of Pathfinder Adventure Path launches the Wrath of the Righteous Adventure Path and includes: "The Worldwound Incursion," a Pathfinder RPG adventure for 1st-level characters, by Amber E.
