A thousand years ago, Sephia, heir to the Spring Origin, sacrificed half her godhood core to save Nektos, the Underworld King's descendant, falling to demigod status and quietly ruling as his hidden Queen. A millennium later, the demigod Minta steals Sephia's crown, claiming to be Nektos' savior. Believing the lie, Nektos burns Sephia's life-sustaining fields, tears the remaining core from her chest with his scythe, and strips her of her title.
Helian, descendant of the Sun God, rescues a dying Sephia and brings her to Olympus, where her true identity as the Source of Spring is revealed. Realizing the horrific truth too late as his own chest cracks, Nektos casts Minta into frozen hell and climbs the Heavenly Path to beg for forgiveness, only to be rejected. When a coup hits the Underworld, Nektos abdicates and sacrifices his remaining life force to return Sephia's core before vanishing into the void. Fully restored, Sephia crushes a vengeful Minta, rejuvenates the three realms, and ascends to the light hand in hand with Helian.
