Neuvillette is the Iudex of Fontaine, and the leader of the Marechaussee Phantom. While Neuvillette upholds the rules of the court with utmost reverence, he is quite aloof when dealing with human emotions and often distances himself from the public. Despite his human appearance, he is the Dragon of Water—the Hydro Sovereign. However, he did not obtain full dragonhood until the Hydro Archon Focalors returned the powers stolen by the Heavenly Principles from the Sovereigns back to him.
