Ur (ウル Uru) was the teacher of Gray Fullbuster and Lyon Vastia, as well as Ultear Milkovich's mother. She sacrificed herself by using Iced Shell to defeat Deliora. Ur, during her time with her daughter, was a good, caring and loving mother. While she trained Gray and Lyon, she was upbeat, cheerful and slightly abrasive. She cared for both of her pupils as her own children, though she became extremely angry when Lyon asked her if he was enough to take the place of Ultear when he learned about her taking Gray as a pupil, causing her to strike him in anger. She also scolded Gray for stripping in public. She was also very humble, as seen when she said that there were many other Mages stronger than her, despite others seeing her as being capable of being one of the Ten Wizard Saints.
