The seven shards of the Shattered Star have been recovered, and the Pathfinders prepare a grand festival on Magnimar's Irespan to celebrate this incredible achievement. The culmination of this celebration is to be the reassembly of the seven shards into the legendary Sihedron itself, rebuilt for the first time in over ten thousand years. But a lot can change in that amount of time, and as the ritual to reforge the artifact finishes, ancient contingencies rumble to life, and as the dead heart of Thassilon begins to beat again, all of Magnimar is put in terrible danger. With the power of the Sihedron on their side, the heroes take a stance against this risen evil but will the aid of an ancient artifact be enough to save them all?This volume of Pathfinder Adventure Path concludes the Shattered Star Adventure Path and includes: The Dead Heart of Xin, a Pathfinder RPG adventure for 15th-level characters, by Brandon Hodge.
