Kelner
Kelner served as Castellan of Gallifrey at the time that the the Doctor returned to Gallifrey to claim the office of Lord President.
Profile
Unlike his predecessor Spandrell, he appeared to by much more of a politician and ambitious. After the Vardan invasion, he assisted the Doctor in removing Time Lords who might oppose the new regime, drawing up lists of those who he had a personal grudge against, such as Surgeon General Gomer. At this point he was told by the Doctor to consider himself as acting Vice President. Andred disliked him but stayed in post because he thought he might be able to lead a resistance movement within the Capitol and act as a foil to the corrupt castellan.
Kelner was equally at home collaborating with the Sontarans who had used the Vardans as a cat's paw to their own invasion. (DW: The Invasion of Time)
- Kelner's ultimate fate is unknown, but it is unlikely that he remained in office after the invasion was defeated through the use of the De-mat Gun.
