Castellan

The Castellan of the Chancellery Guard, (TV: The Deadly Assassin) also known simply as the Castellan, was a high-ranking Time Lord who oversaw the Chancellery Guard.

Role
The commanders of the Chancellery Guard reported to the Castellan. As the Guard were responsible for security within the Capitol and the personal security of the President, the Castellan was often in direct conflict with the Coordinator of the CIA whose remit was external threats to the planet or to the integrity of the timeline. (AUDIO: Pandora) The Castellan was the Capitol equivalent of a Chief of Police. (PROSE: The Eight Doctors)

President Borusa raised the position of Castellan to one that sat on the High Council, with the first to do so being Jerricho (PROSE: A Brief History of Time Lords) who also went on to sit in the Inner Council. (TV: The Five Doctors) In Spandrell's time, the Castellan's duties involved him more frequently with the "plebeian classes" of Gallifrey than with suspect Time Lords. (TV: The Deadly Assassin) Castellan Kelner, by contrast, was second in line to the Presidency, after the Chancellor. (TV: The Invasion of Time)

The position was mandated by some of the most ancient and powerful Gallifreyan laws. (AUDIO: Lies) Even so, the laws of Gallifrey apparently gave the Presidency wide discretion in deciding which matters were handled by the Castellan, and which by the Coordinator. Lady President Romana II, for instance, once simply chose which of the two she wanted to handle a matter. (AUDIO: Pandora)

The Castellan was outranked by the Coordinator of the Celestial Intervention Agency. (AUDIO: Enemy Lines)

History
Each chapter had a Chapter Castellan. Often the Castellans of the Chancellery Guard had served in the Guard prior to their elevation. Both Maxil and Andred served in this way. Others appear to have been political appointments, like Kelner (TV: The Invasion of Time) and Wynter. (AUDIO: Lies, Pandora, PROSE: Lungbarrow)

Nine of one Castellan's strike force were killed by members of the Order of the Black Sun during the Black Sun War. (COMIC: 4-D War)

The rogue Time Agent Scott Thrower took the alias of "Castellan Bond" on Helion in an attempt to use the solstice of Pajaro to rejuvenate himself, accompanied by a group of Gizou mercenaries disguised as Chancellery Guards. (COMIC: Time Fraud)

In her position as the caretaker of House Ixion and leader of the Order of the Weal, Thessalia claimed the title Chatelaine, the feminine equivalent of "castellan". (PROSE: The Book of the War)

After President Rassilon dissolved the Chancellery Guard, the position of Castellan was redundant and its incumbent, Castellan Bovari, was reassigned to the Archives as an administrator. (AUDIO: Havoc)
