The Legendaries are a group of heroes tasked with protecting the world of Alysia from powerful threats. But during a battle against the sorcerer Darkhell, a catastrophe known as the Jovénia Incident transforms every inhabitant of the world into a child. Blamed for the disaster, Danaël, Jadina, Gryf, Shimy, and Razzia go their separate ways before reuniting several years later in the hope of repairing their mistake. Their quest takes them across Alysia through magic, fantastic peoples, rivalries, and ancient legends, while they face new enemies and try to restore their honor.
