Hallan

Commander Hallan acted as a personal bodyguard to many former presidents of Gallifrey before he accompanied Romana and Leela to the holiday world of Davidia - he had been there many times and knew the staff there well. One of them, Melyin, tricked him into getting caught in a compromising embrace, in order to have her contract terminated. (BFG: Spirit) Hallan was privately very conservative and disapproved of Romana's reforms on Gallifrey, and consequently supported Darkel's challenge of Romana's authority. However, in the ensuing election, Hallan surprisingly sided with Romana when she declared herself Imperiatrix, arresting Darkel and the High Council.

After the appearance of Pandora and her assumption of power, Romana was freed from her cell by Hallan's guards and he became the military leader of the resistance to Pandora's rule. Having destroyed the means of using any TARDISes, Hallan and Romana escaped the city and made their way to the Celestial Intervention Agency's Anomoly Vaults to retrieve the one functioning TARDIS on Gallifrey, using it to secretly return to the destroyed Time Lord Academy. Whilst Hallan led the resistance inside the city, Matthias contacted Darkel and passed on an infected disc from her to Hallan, who was infected and had to enter stasis until a cure could be found.
