- "I am the world carver! The endless torment!"
Illyria released him at his full power when she destroyed the sarcophagus that sealed him. As Arsgomor intended to reconquer the world, Illyria stood against him. Using the powers she recovered from the Deeper Well, she bound him with plants and used her temporal manipulation abilities to revert him into a fetus. During the confrontation, Arsgomor managed to kill one of Illyria's pet demons.
Illyria handed the Old One into the custody of the Keeper of the Deeper Well for the next thousand years, so that with her influence, the demon would have a chance to become a different being.
