Description, by Lois Tilton [Locus]: "This is an aftermath story, where we begin in the ruins of past events and hope to learn what came to pass. Which turns out, as it often the case, to have been sorcery misused. There were once a king, his mage, and his general, who refused to serve the evil they raised."
