Time Lord President

The Time Lord President is the ruler of the Time Lords on Gallifrey. He occasionally enlists the help of the Doctor when he feels the situation requires him, though he is often unsure as to why he would choose someone who is mostly unwilling to help his people.

Character History
It is unknown at what age or time in his life the current President was bestowed the title, but one of the most significant events during his presidency was allowing the Doctor to imprison the Vultures in the Quantum Ark. After summoning him to Gallifrey, the President was persuaded by the Doctor that the Vultures should not be killed, but imprisoned inside the Quantum Ark, thus avoiding mass genocide. The technology for the Quantum Ark was not improved however, which resulted in the Vultures escaping 100 years later. During this time, the President regenerated into a new body.

In his new incarnation, the President found himself and his people at the mercy of the Vultures once more. He summoned the Doctor again, who on his own was unable to provide much help. Therefore, the President summoned another Doctor to help in the fight against the Vultures. Whilst the Doctors, Jess and Caldril, Castellan to the President, defeated the Vultures, the President stood watch over the Citadel. Upon the Vultures' defeat, he offered the mantle of President to the Doctor, who declined, leaving the President to continue his job.
