Castellan

The Castellan was a member of the High Council of Time Lords responsible for overseeing the Chancellery Guard and therefore order on and the security of Gallifrey. The various Commanders of the Chancellery Guard itself acted as the Castellan's subordinates.

The position was protected by some of the most ancient and powerful Gallifreyan laws. (BFA: Lies)

There may have been a Castellan for each of the Chapter Houses, with one of them serving as the 'duty Castellan' in overall charge of the rest. Often the Castellan's had served in the Chancellery Guard prior to their elevation. Both Maxil and Andred served in this way, others appear to have been political appointments, Kelner and Wynter. (BFG: Lies, Pandora, NA : Lungbarrow, DW: The Deadly Assassin, The Invasion of Time)

It is possible that the un-named Castellan in The Five Doctors is Kelner regenerated as he states that "The Doctor wants revenge", he may be hinting to the events and his betrayal in The Invasion of Time, however this would assume he was pardoned following his arrest at the end of this serial. This contradicts The Doctor's statement that he believes the Castellan was not a traitor, although if he was indeed Kelner regenerated he may have "reformed" but due to his actions in The Invasion Of Time he would still be under suspision, thus making him the perfect scapegoat for Borusa.
