Evil creatures called Nemeses fall from the skies and the only ones who can fight them are Wizards--infected ones who survived a Nemesis's corruption. Seth, one of these survivors, vows not only to fight the Nemeses, but to find their mythical nest, Radiant, and destroy it!

Seth's grueling training at the Artemis Institute continues under his new teacher, Yaga. Despite Yaga's best efforts, Seth is still having trouble using feather tools to manipulate Fantasia. Will Seth be able to overcome this hurdle? Meanwhile, the Inquisition and Dragunov keep a close watch on Seth, waiting for the young wizard and his friends to leave the protection of the Artemis Institute to capture him!
