Layla, ex-High Priestess of Delphi, sacrificed her sacred voice to save Cassian, heir of the Temple of the God of War. Deceived by a fake divine oath, she spent three years suppressing demons in the wild. She returned with the Demon Emperor’s head, walked in on the betrayal wedding, and was hurled down a cliff. Dying, she awakened Kael, the Underworld Lord sealed by Zeus for a thousand years with her mutated divine blood, trading her soul for revenge power. Disguised as a besotted old flame, Layla fought against the temple again and again. She and Kael fell in love beyond their contract. Crowned Queen of the Styx, she vindicated Kael, retrieved her sacred voice, gave birth to divine heirs, and brought peace to the Underworld and Olympus.
