Three hundred years ago, High Immortal Celestia shattered her spiritual core to seal the Demon Lord and was reincarnated as Elara Shaw, a concubine's daughter of the Shaw Clan. The seal weakens and demonic energy leaks out. She sets up a barrier to protect her home, but her clan members break through it and are consumed by the demonic energy. She waits alone for her Twelve Disciples to retrieve the fragments to reforge her spiritual core and permanently suppress the Demon Abyss.
