Nial spoke a little bit more with the Oracle which allowed him to get to know a bunch of things.
The Oracle said that she left the Origin to visit a place where she did not only regain her strength but where she observed the progress of the Undying, a human, who was considered a Fate Changer, just like Nial.
Both he and the Undying were mentioned in the first prophecy of the Universe, according to the words of the Oracle, and certain preparations had been completed to help them be ready for what would happen.
She mentioned Veils, cracks in the void that could also be considered Gateways connecting Universes, and the emergence of Vile Existences, called Veilures. Veilures devoured everything in their surrounding area, whether it was mana, the living, or mere objects. As for their reason to devour everything, the Oracle didn't specify why that was the case.
