Socra (The War Games)

An incarnation of Socra was a member of the Tribunal and Chancellor of the High Council.

Biography
Alongside the councillors Goth and Adelphi, Chancellor Socra (PROSE: The Legacy of Gallifrey) was part of a council of three who tried the Second Doctor on the battleground-planet of the War Lords, eventually condemning him to a force regeneration and exile on Earth. He was also present for the War Lord's trial, and he watched as the War Lord and his guards were dematerialised. He escorted Zoe Heriot and Jamie McCrimmon to say goodbye to the Doctor before they were returned to their home time periods with their memories of the travels erased. (TV: The War Games)

Socra was asked by Rassilon to look out for the Third Doctor during his exile on Earth, and convinced President Pandad IV to send another member of the High Council to Earth to warn the Doctor that had escaped their grasp and was now out for revenge. (PROSE: The Legacy of Gallifrey)

At some point, Socra regenerated into a new body. (PROSE: Doctor Who and the Doomsday Weapon) After a report on the Doomsday Weapon went missing from the Time Lords' files, he was part of a group that decided to send the Third Doctor to the planet Uxarieus to investigate. (TV: Colony in Space) This incarnation appears to be brief, however, as Socra had returned to using the body of the incarnation involved in the Doctor's tribunal by the time of the First Omega Crisis. (TV: The Three Doctors) Indeed, Postar the Perfidious apparently thought this incarnation didn't even merit inclusion within the Scrolls of Gallifrey. (PROSE: The Legacy of Gallifrey)

A Senior Time Lord, (PROSE: The Three Doctors) Socra was still Chancellor during the First Omega Crisis, when help from the first three incarnations of the Doctor was required. He objected to President Pandad IV's plan to have the Doctor cross his own time stream, citing the First Law of Time. (TV: The Three Doctors) At the end of the crisis, he insisted with the President that the Doctor had earned his freedom. When Pandad IV demanded a more candid explanation, Socra was authorised by Rassilon to reveal the existence of the CIA to him, though Pandad chose not to make it public so as not to weaken the population's faith in the Presidency.
