The seven components of The Fragmented Star have been recovered, and the pathfinders are preparing a great festival in the Wrath Arcade of Magnimar to celebrate such an incredible achievement. The culmination of this celebration is the reforging of the seven components into the legendary Siedro, reconstructed for the first time in over ten thousand years. But when the ritual to reforge the artifact is completed, ancient contingencies come to life, the dead heart of Thassilon starts beating again, and Magnimar is in tremendous danger. With the power of the Siedro on their side, the heroes oppose this resurrected evil, but will the help of an ancient artifact be enough to save everything?
