Rigan

 was the coordinator of the Celestial Intervention Agency, who despised being on Earth amongst humans. She told Johannes Rausch about his death. She didn't trust the Seventh Doctor and thought he was faking his symptoms. She shot Louis who then regenerated. She was annoyed at the actions that Klyst used, so overruled her and took control of the institute. She asked for help to destroy the facility. (AUDIO: Unregenerate!)
