In her past life, the protagonist Eilara was betrayed by the clan leader Ragna and his granddaughter Lilith; they stole her dragon, framed her for a crime, and cast her into the abyss to her death. Reborn, she abandoned her dragon, broke the curse binding her, and sought out an ancient dragon, yet she could not fully escape the reach of dark sorcery. Driven to despair, she plunged into the Abyss of the Evil Dragon and used a forbidden spell to transform herself from human into dragon, emerging as an uncontrollable, supreme Dragon Lord. Ultimately, she returned to the Selection Ceremony, exposed the conspiracy, slew her enemies, and became the true High Priestess of the Dragon-Riding Clan.
