Savar

Lord Savar was a Time Lord.

Early life
Like all Time Lords, Savar 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, Savar was inspired by what he saw in the Schism. (PROSE: A Brief History of Time Lords)

When the Doctor was young, Savar beat him at chess. The humiliation of defeat almost made the Doctor cry. (PROSE: The Infinity Doctors)

The Omega mission
Savar planned a mission to rescue Omega from the black hole he was trapped in. He intially had Ulysses' help, but Ulysses remained on Gallifrey when Savar set out on the mission. In the black hole, his TARDIS was damaged. (PROSE: The Infinity Doctors) He actually came face-to-face with Omega, but, in his strained state, believed him to be the ancient Gallifreyan deity Ohm. Mad with fear, (PROSE: Gallifrey: A Rough Guide) he had to flee in his TARDIS's escape pod.

His escape pod was intercepted by the I, who stripped his escape pod, taking all relevant technology. However, as Time Lord technology utilised retinal technology, they also extracted his eyes. (PROSE: The Infinity Doctors, PROSE: Seeing I)

Later life
Savar was rescued and, after a regeneration, he had his sight restored. He continued claimed to have seen tOhm, and also that he had "fallen off the edge of N-Space". These events left him with multiple personality disorder, with two distinct personalities. In this body, he was also an accomplished telepath. (PROSE: The Infinity Doctors)

Savar was on Gallifrey when the Fourth Doctor was installed as Lord President of the Supreme Council of the Time Lords. Lord Gomer spoke to him about the cyclic burst ratio and wavelength broadcast power induction at the coronation. Gomer believed Savar was due for a regeneration. (TV: The Invasion of Time)

Personality
Savar was not known for any unnecessary mental activity and was quickly bored of Gomer's discussion of wavelength broadcast power induction. (PROSE: Doctor Who and the Invasion of Time)
