The Doctor (Auld Mortality's universe)

This incarnation of the Doctor never left Gallifrey, becoming an author instead of a renegade Time Lord. He wrote the first science-fiction historical romance, An Adventurer in Time and Space with the Possibility Generator. His other works included A Journey to Ice-Askar, the Winter Star and An Exciting Adventure with the Hassites. His stories were popular with generations of Gallifreyan children.

His granddaughter Susan, whose mother was his daughter, eventually became the Lady President of Gallifrey. By this time, she had two grandchildren of her own, a boy and a girl. (BFDWU: Auld Mortality)
