Lord Savar was a Time Lord.
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)
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 and he had to flee in its 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) Savar was rescued and, after a regeneration, he had his sight restored. He also claimed to have seen the Gallifreyan god Ohm and 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)
