Goth

Gothaparduskerialldrapolatkh (or Goth for short) was a Time Lord politician and occasional agent of the Celestial Intervention Agency. As Lord Chancellor, he became a pawn of.

Biography
Like all Time Lords, Goth 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, Goth was driven mad by what he saw in the Schism. (PROSE: A Brief History of Time Lords)

Goth was a member of the Celestial Intervention Agency. (PROSE: Legacy)

On behalf of the CIA, Goth masqueraded as the fictional character Lemuel Gulliver in the Land of Fiction to monitor the Second Doctor. On Gallifrey, Goth, alongside two other Time Lords, presided over the trial of the Second Doctor, (PROSE: Future Imperfect) which resulted in his exile on Earth and a forced regeneration into his third incarnation, (TV: The War Games) though another account held that it was a different Time Lord, no less than the Lord President of Gallifrey, who had presided over the Second Doctor's trial. (PROSE: The Three Doctors)

Goth was a member of the tribunal that, following the events of the War Games, put the War Lords, the War Chief, and the Second Doctor on trial. He argued that certain experimental human subjects of the War Lords be killed, rather than returned to their own time - an opinion which the other two judges disagreed with. (PROSE: War Crimes, TV: The War Games)

When Goth became Chancellor, he persuaded the CIA to send the Third Doctor to Peladon. (PROSE: Legacy)

Alliance with the Master
Goth travelled to the planet Tersurus and found, who was now at the end of his regeneration cycle and physically little more than a decaying corpse. (PROSE: Legacy of the Daleks, AUDIO: The Two Masters) Having been told by the Lord President that he did not intend to name Goth as his successor, the Chancellor entered into an uneasy alliance with the Master, who promised him the presidency in exchange for helping to kill the Fourth Doctor.

More than happy to help if it helped him gained the Presidency, Goth subsequently assassinated the President before he could announce his successor, setting up the Doctor as an unwitting decoy assassin. The result should have been an unopposed election for the office. However, the Doctor announced his own candidacy to buy himself time to investigate.

Inside the Matrix, Goth fought the Doctor, initially using his knowledge of the Matrix's workings to his advantage. The Doctor soon gained the upper hand, however, and the infuriated Master tried to overload the Matrix by sending a massive energy spike through Goth's brain.

The Doctor escaped from the Matrix in time, but the spike had fatally damaged Goth's brain. The Doctor found Goth and the seemingly dead (but actually self-sedated) Master not long after. The dying Chancellor told the Doctor how he and the Master had come to be allies, and why he wanted to kill the previous President.

Goth died shortly afterwards, and it was decided by Borusa to cover up the actual truth of his death. He decided on telling the population that "Chancellor Goth tracked [the Master] down and killed him, unfortunately perishing himself in the exchange of fire". (TV: The Deadly Assassin)

Personal details
Goth had a brother named Rath. (PROSE: Blood Harvest)
