Ba'ul and Judith have been companions since she was very young. The Krityans who lived on Mt. Temza feared Ba'ul, believing him to be a dangerous monster, but Judith did not view him this way, befriending him instead. Ba'ul saved Judith during the Great War, which occurred ten years prior to the events of the story. Ba'ul is Judith's transportation, and when she speaks of her partner, she is referring to Ba'ul. He travels with her, sensing the disturbance of aer and bring her to blastia, which she destroys. Later, when Ba'ul is trying to evolve at Mt. Temza, Judith guards him, knowing he is vulnerable due to his injuries. Tison and Nan attempt to kill him, but the group protects him, and he evolves into a large enough form to carry the Fiertia.
