Matilda, Abigail, and Lucifer, former heroes, assume leadership roles as they grow older and must grapple with love, grief, political alliances, and the burden of power. Meanwhile, a new generation, including George, Violet, and Ben—the children of the original heroes—begins their own journey as soldiers. They carry on the ideals of their predecessors while facing a universe filled with threats, conspiracies, and deep-rooted injustices. Across the galaxy, various empires clash and negotiate, each with its own motives, while the Omnis Empire expands its influence through diplomacy, warfare, and ideology.
On the planet Vovli, a war rages between the Giant Tribes and the soldiers of the Omnic army, including Lucifer and his daughter Ruth Lavender, as well as Abigail Smith. After the battle, Matilda and Landon go to the Court of the Kings with Omnic Army General William Davies.
