The Kingdom of Gernia is expanding its possessions, conquering and forcing them to settle down, and even destroying nomadic tribes. The inhabitants of the plains have natural magic; Gernia, on the other hand, relied on modern weapons, and she confidently wins. But she still needs professional warriors. There has long been a tradition: in a noble family, the first son receives his father's inheritance, the third becomes a priest, and the second gets the lot of a soldier. Nevar Bourville, the second son of a man named Lord for his military merits, enters the prestigious Royal Cavalla Academy. The young man boldly hopes for a brilliant career as a cavalry officer, but soon discovers that the road ahead of him is far from straight. He finds himself caught in a web of injustice, intrigue and dirty games. And he still does not know that a special fate awaits him - to become a link between the ancient magical world and a rapidly developing civilization.
