Roubaul

Roubaul is the Guild Master of the Cait Shelter Guild, he looks similar to an Native American chief with a moderate sized white beard. He also has a bad habit of opening his mouth when he is drinking sake to say something important. He apparently believes "Nabura" is shining down on his guild. After the guild defeated the Nirvana, they met up with the other and he stated that they are not the descendants of Nirvit but are the Nirvit. He also claimed that he created the Nirvana 400 years ago. He also said that he is a spirit waiting for the mages who could defeat Nirvana. Seven years ago, a boy brought Wendy, and even though he had vowed to live alone, he was taken aback by his clear and earnest gaze, so he decided to stay with her. When she woke up and wondered where she was Roubaul responded that she was in a guild with wonderful mages. He then created a guild for Wendy to be happy in. He gave both Wendy and Charle a tearful farewell and asked their true companions to watch over them.

Magic and Abilities
Illusion: He has without question the strongest illusion magic seen to date that not even Erza's Fake Eye could see through. Even Jura stated that his magic was frightful. Not only can his illusions have their own emotion and personality, but can actually take a physical form and do actual life-like things. Not only that, but Roubaul's illusions are self-sustainable (unless by their own will to go or ultimately by Roubaul's will). Another possibility is that his magical capacity is so vast, that he alone is keeping everything intact for seven years straight. This might also explain why only Wendy and Charle were the only ones to go on the mission. However, due to Nirvit's background of being neutral, it's most likely that his illusions are not meant to be destructive. Which explains why he can't destroy Nirvana himself. It is still unknown if his illusions can be considered living beings (until there source of existence is gone).
