Yvane and the Vaïndrians have succeeded in occupying Vorlille Fortress, but their adventure has only just begun. As they adapt to life with the Edelstein, new concerns arise within the fortification while their alliance with the Perussians of Vorlille Town alters their political stance on the Eidalyne Plains. In the Anstelle Forest, Ricardine and Biron, who are still struggling after their separation from Temi, find themselves in new company, while in the Kingdom of Forlì, the interests of King Rheni III Vensze-Davel and the family of Avi Téron (the Regis of Vinlesse) begin to broaden the world in which the Vaïndrians must learn to survive.
