After Rebirth, I Let My Sister Become Apollo’s Oracle

In her past life, Kallia, the Oracle of Apollo, was betrayed by her sister Helena and husband Leon and perished in flames. Reborn on the divine selection day, she abandons Apollo's altar and chooses Selos, the Underworld covenant bearer who once tried to save her. Helena seizes Apollo's glory, but greed drives her to taint her bloodline and drink venomous wine. She gives birth to a deformed child and is dragged underground by the Erinyes. Kallia gains equal love and respect in the Underworld, retrieves her child from her past life, and bears Fate-recognized heirs. She finally breaks free from shackles, guards the Styx boundary with Selos, and embraces true rebirth.
