Marnal

Marnal was a Time Lord. He was the previous owner of the Doctor's TARDIS. In his childhood, the Doctor considered Marnal to be his hero.

Marnal was the Castellan on Gallifrey before the Doctor left the planet. Marnal was exiled to Earth in 1883. He was placed in the care of a Mrs. Gate. Under the name Marnal Gate, Marnal became a science fiction author, and met Mervyn Peake, who illustrated one of his novels, and H.G. Wells. Marnal had amnesia about Gallifrey and the Time Lords, but he remembered enough to write novels containing the entire history of Gallifrey; Marnal did not know that Gallifrey was a real place.

Marnal had a son on Gallifrey (possibly The Master). He also had four adopted daughters on Earth from his wives' previous marriages, whom he described as parasites.

In 2005, he regenerated into from his twelfth to his thirteen incarnation. The surge of artron energy restoring his synapses in the regeneration returned his memory.

His thirteenth and final incarnation was killed by the Vore. Before he died, the Doctor told him that he was his childhood hero. (EDA: The Gallifrey Chronicles)

Trivia

 * If Marnal is the Master's father, then he would have own estes on Gallifrey's mountains (DW: The End of Time)
 * Many of Marnal's works are refrences to previous Doctor Who works. They include The Witch Lord (DW: Full Circle); The Giants (DW: The Giants' ); The Hand of Time (DW: The Hand of Fear' ); The Monkey to Time Saga (possibly The Key to Time season ).
 * The Witch Lords was a title by Terrence Dicks for a serial back in 1977, but had to drop it in favour for DW: Horror of Fang Rock. Dicks eventually remade The Witch Lords in 1980, for DW: Full Circle.
 * The Hand of Time was originally the title of DW: The Hand of Fear.
