Sybil of Cumae

This is my OC from my fanfiction "Trinity Blood: Revelations." The Sybil was a seer of the Roman Empire and even predicted the coming of Christ, which centuries later gaver her an honorable apperance in the Sistine Chapel by Michaelangelo. The Sybil was known for appearing before great turning points in human history, giving prophesies that would lead the involved humans to a great era of peace or disaster, if they chose to listen to her. However, 450 years before the Armageddon she vanished. Two years have passed after the events in Trinity Blood but after 1399 years the Sybil has returned. Does her coming mean the world is to now become the ashes the Contra Mundi desires or will it be renewed and be lead into a era of peace and prosperity?
