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!

Lords from all over Cyfandir are gathering to choose young Wizard Knights deserving of being their heirs. Seth, meanwhile, continues training with his mysterious tutor in the even more mysterious Caillte Forest, where strange creatures roam and time flows at a very different rate from the rest of the world. While there he also learns of the "Little People" and that he could very well play an important role in helping them to return from near extinction.
