This is the story of a lost world of Greek mythology, where destiny rhymes with adventure. Maxence, a high school student who dreams of Poseidon's trident, will meet a new student, Marine, who tells him everything about his origins. He is the medallion bearer of the god of the seas and the pretender to the throne of Atlantis, one of the seven human kingdoms of the world of the gods. A great epic is then launched for him and the other bearers of power, whose mission is to protect their people from the forces threatening them, under the eye of the Olympian gods perched on their mountain. But now a former ally has emerged from the ground, with a heavy heart and full of revenge.
