Dahin, a beloved member of the Witch King's coterie, believes he has clues to the location of the Hierarchs' Well, and the Witch King Kai, along with his companions Ziede and Tahren, knowing there's something he isn't telling them, travel with him to the rebuilt university of Ancartre, which may be dangerously close to finding the Well itself. Can Kai stop the rise of a new Hierarch? And can he trust his companions to do what’s right?
