The arrival of the Hero escalates a generations-long war, threatening to plunge the world into an apocalyptic conflict. As forces gather from across the continent, Tani and her allies finally have a chance to make a difference, but it means confronting one of the most dangerous warriors alive. The Zeitai also desires war, and the combined forces of the Hero and Zeitai could bring about the end of everything.
With time running out, everyone scatters before the final battle. Tani seeks a legendary warrior, Slaten delves into forbidden ancient histories, and Celivia struggles with conflicted loyalties between warring factions. Every ally they've gathered across the Expanse, mountains, and Maenhu will face their ultimate test, as the Hero continually finds new ways to make things worse.
