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.
