Jerricho (PROSE: A Brief History of Time Lords) held the post of Castellan for some time during the Doctor's fifth incarnation. He was more commonly referred to by his title. (TV: Arc of Infinity, The Five Doctors)
Like all Time Lords, Jerricho was taken from his family at the age of eight for the selection process in the Drylands. Staring into the Untempered Schism as part of a Time Lord initiation rite, Jerricho was inspired by what he saw in the Schism. (PROSE: A Brief History of Time Lords)
As Castellan, Jerricho was responsible for matters relating to security on Gallifrey and answered to Lord President Borusa. He was on Gallifrey during Omega's attempt to harness the Arc of Infinity. He attempted to kill the Doctor to stop Omega bonding with him but instead killed Hedin, who jumped in front of the Doctor to save him and allow the bonding to take place. (TV: Arc of Infinity)
During the Death Zone crisis, Jerricho was among the High Council members who received the Master on Gallifrey to send him into the Zone. Jerricho gave the Master a transmat device to return to the Capitol. When the Doctor and the Master were ambushed by Cybermen, the Doctor used it to escape. Wondering how the Cybermen found him so quickly, the Doctor found a homing beacon inside the recall device, the one thing the Master would be certain keep on him. Borusa observed that Jerricho had given the homing beacon to the Master, to which Jerricho replied that this was the Doctor trying to take revenge on him for his previous attampt in his life.
President Borusa immediately ordered a search of Jerricho's rooms. The guards discovered a chest containing the Black Scrolls of Rassilon, which Borusa then destroyed. The President ordered Jerricho interrogated using the mind probe, much to Jerricho's distress. Moments later, Jerricho was shot and killed by a Commander of the Chancellery Guard, apparently after trying to escape. In truth, Borusa had been behind the Death Zone crisis and had framed Jerricho. (TV: The Five Doctors)
The Fifth Doctor believed Jerricho to be limited, narrow and ruthless when he thought it was necessary. He was also fiercely loyal to his oath of office and horrified by any mention of the Dark Days. (TV: The Five Doctors)
Behind the scenes
- Sean Arnold and Patrick Stewart were considered for the role before Paul Jerricho was cast.
- Jerricho's name comes from his actor's surname.
- The character reappeared in 2020 in the Doctor Who: Lockdown!-adjacent webcast The Castellan has returned and has brought a message from Gallifrey!, tying in with a tweetalong of The Five Doctors. Played by a visibly older Paul Jerricho, the Castellan cackled that "Time Lords never die" to explain how he was still around, and greeted the viewer from the depths of the jungles of Wild Endeavour before being attacked by the Time Scoop as part of what he (in another fourth wall break) recognised as "the tweetalong". Due to these factors, the webcast is not considered a valid source on this Wiki.
