Third Time Lord

From Tardis Wiki, the free Doctor Who reference

The titles of First Time Lord, Second Time Lord and Third Time Lord referred to "the three most superior Time Lords".

A First, Second and Third Time Lord formed the High Tribunal (PROSE: Doctor Who and the Doomsday Weapon) who sentenced the Second Doctor to his exile on Earth. The Third Time Lord present during these events, (TV: The War Games) Chancellor Socra, (PROSE: The Legacy of Gallifrey) still held the title, but now in a new incarnation, when he and the other two pondered what to do about the Doomsday Weapon crisis. (TV: Colony in Space, PROSE: Doctor Who and the Doomsday Weapon) However, during the First Omega Crisis, Socra, (PROSE: The Legacy of Gallifrey) referred to as Chancellor, once again looked just as he had (TV: The Three Doctors) during the Doctor's trial.
