Errial-Thea, a world ruled by winged people, who are divided into the powerful and the poor. The wings of the former are huge because they have wealth; the wings of the latter are similar to the wings of newborns, because their size depends on the level of happiness. The main character, Prince Leraish, is preparing to become an archon, but does not undergo initiation. Having learned the truth about the real world order of his world, he turns into a sheidim, a creature with black eyes who loses his mind, according to popular belief. Having been exiled and deprived of his wings, he finds other sheidim, whose leader reveals to the prince his plans that he wants to start a war against the Hegaldin in order to save his people.
