To secure her false identity as the princess of Minos, Elina schemes to make the real princess, Selene, take her place as the sacrificial bride of the Underworld. In the realm of the dead, Selene is humiliated and forced into the lowest form of servitude by the cruel high priestess Cassandra. Elina later arrives as a royal envoy, eager to watch Selene burn in the flames of the Underworld. But during the sacred ritual, the hellfire bows before Selene, transforming into a lotus beneath her feet. A long-lost divine symbol appears on her forehead, revealing her true identity: Persephone, the Queen of the Underworld, who vanished ten thousand years ago after sacrificing herself to save Hades. The God of Death kneels before her, strips Cassandra of her divine status, and presents Selene with his scepter. Selene brands Elina's face with the mark of a liar before returning to the mortal world to unleash divine punishment and investigate the betrayal that destroyed her ten thousand years ago. She discovers that the true mastermind is Helios, the Lord of the Sun, while the ancient God of Chaos, Erebus, remains sealed beneath the royal palace. To protect the world, Hades merges his divine essence with the seal. Selene reunites the two halves of their divine power and leads ten thousand years of restless souls in a counterattack, sacrificing herself to reseal Erebus and reclaim the remnants of her beloved's soul. Elina is eventually crowned queen, only to become a mere undertaker. At last, the sacrificial pact is rewritten: sacrifice must be voluntary. Together, Selene and Hades stand side by side, protecting both the mortal world and the Underworld.
