Arion is a young shepherd living in Thrace alongside his blind mother, the goddess Demeter. Their existence remains tranquil until Arion's uncle, Hades, arrives and entices him to the underworld, promising a method to restore his mother's vision. To accomplish this, Arion must kill the god who cursed her: Zeus, the king of Olympus. Following years of training in the underworld, Arion—now a lethal warrior—sets out on his vengeful mission to slay Zeus. During his journey to Mount Olympus, Arion forms alliances with several unlikely figures: the giant Geedo, the thief Seneca, and the mute maiden Resphoina. As he carves a bloody path through a vast world filled with warring armies and mythical monsters, Arion starts to uncover the secrets of his lineage and the fate of the scheming gods.
