More scattered cards of the mysterious and powerful Harrow deck known as the Deck of Destiny must be gathered before those who would use the Harrow's power to alter fate itself for their own needs can get them first. But this time, the cards come to the heroes when one of their competitors grows aggressive and attacks them in their own home. Only by gathering allies, exploring an ancient ruin, and exploring a corrupted demiplane can the heroes stand a chance over their latest enemy—a demonic mercenary who's taken an apocryphal Harrow card as his own identity.

The Destiny War is a Pathfinder adventure for four 14th-level characters. This adventure continues 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. This adventure also includes new magical items and treasures to be discovered, including another 18 powerful cards from the Deck of Destiny, and a mix of monsters to torment the player characters.

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.
