Fan Casting What If Doctor Who Wasn't Axed? - Doctor Who: Vengeance (2010)

The Rogue has been comfortably in office as Lord President of Gallifrey for the past few years, but one day suddenly everything changes. The long lost former Lord President, Gregori, is found in an old Gallifreyan ship, drifting in space, with his crew. Now returned to Gallifrey, Gregori wants his title back, and the only way to claim legitimacy is from an Ancient Gallifreyan Law, which the only evidence of resides in a book... which happens to have disappeared. Now Gregori embarks on a quest to find this book. The Rogue, fearful of Gregori, calls upon the Doctor to find this book before him and destroy it. A remake of Douglas Adams' unfinished story, Shada.
