Scion of Cyador is the 4th book in Modesitt’s Recluce saga to be told from Chaos’s viewpoint, in the person of the Mirror Lancer, Lorn. In "Magi’i of Cyador" (set several generations before "The Colors of Chaos", when Cyador was still ruled by an emperor whose 3-pronged powerbase rested on the shoulders of the White Order, the mirror lancers, and the great merchant families, we met Lorn, and his mage family, witnessed his dismissal from the White Order, and his progress within the lancers, while our understanding of Chaos society deepened along with his, as he survived attacks by barbarians, wild beasts, plotting supervisors, and assassins, to wed his Trader beloved. In "Scion of Cyador", Lorn is still a junior officer attempting to understand how his homeland functions. As he moves from over-captain in a trading port to sub-majer in a frontier fort to majer in Cyad itself, he observes how Cyador is changing: the rising merchant families want lower tariffs, while the mirror lancers need more funds for armament to defend the frontier, and the mages oppose any change that will lessen their power. We learn as well, since, as always, Modesitt layers his story (the fast-paced adventure of Lorn’s rise in the mirror lancers, while fighting off accusations and assassination attempts by those whose power-base he threatens, is mirrored by Lorn’s self-education in how his society works, aided by his merchanter consort, and again by Lorn’s survival in the political atmosphere of the White City, Cyad, while he ponders the question posed by his dead father, “what is the origin of power?”). In other words, as in all his books, the deeper one reads, the more Modesitt forces the reader to think. While Lorn works to keep Cyador viable, backing the development of steam engines to replace the dying Chaos towers, he must foil the political plotting of merchants, mages, and lancers out for themselves alone. As the fast-paced novel races toward a bloody coup in the streets of the White City, we as readers race with it, anxious to discover if Lorn can preserve his homeland and its people.
