Claude confronts Maria. She reveals her pact but insists Eligius is not evil. “He was cast out for refusing to let a child die of plague. He taught me that mercy has no rules.” Claude draws a silver crucifix. But before he can act, the abbey is attacked by The Hollow Choir — a rival cult of nuns who made pacts with a worse entity: the Silence , an angel that erases memory, identity, and free will. They want to absorb Maria’s pact into their own, creating a god of oblivion.

To avoid the tragic fate of her previous incarnation, she vows to hide her immense holy powers.
