The final cards of a powerful artifact based on the legendary Harrow deck finally lie within the grasp of the heroes who seek to defend the very future of reality from being set in stone, but fate itself has its own plans. Will the heroes of Stolen Fate make their own way into an unknown future and clash against the very creators of this potent magical artifact, or is destiny truly a force that cannot be withstood? "The Worst of All Possible Worlds" is a Pathfinder adventure for four 18th-level characters. This adventure concludes the Stolen Fate Adventure Path, a three-part monthly campaign in which a band of adventurers are thrust into the role of the defenders of destiny itself. Each monthly full-color softcover Pathfinder Adventure Path volume contains an in-depth adventure scenario, stats for several new monsters, and support articles meant to give Game Masters additional material to expand their campaign. Pathfinder Adventure Path volumes use the Open Game License and work with both the Pathfinder RPG and the world's oldest fantasy RPG.
