From the back of the book: An Ancient Heart Beats Again! 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 10,000 years. But as the ritual to reforge the artifact is completed, ancient contingencies rumble to life, the dead heart of Thassilon begins to beat again, and all of Magnimar is put in terrible danger. With the power of the Sihedron on their side, the heroes take a stand against this risen evil—but will the aid of this ancient artifact be enough to save them all?
