Claire Spencer was the commander of an Antarctic base. Prior to the Doctor's first encounter with her, she met him when the pair became involved in an ordeal during which he told her of the importance of fear. She later encountered the Seventh Doctor and employed him to find out who murdered a delegate. She aided the Doctor when Nobody No-One invaded the base, and told him that she had met him at a later point in his life. She was killed when she jumped in front of gunfire aimed at the Doctor, sacrificing herself to save his life. (AUDIO: The Word Lord)
