T ~ Turlough, Vislor - Probably best known as the only companion who deliberately tried to kill the Doctor of his own free will, Turlough was a political prisoner, exiled to Earth after a civil war on his home planet of Trion. Desperate to escape, he agreed to an offer made to him by the Black Guardian - kill the Doctor and regain his freedom. Little is known about Turlough's life on Trion before and during the civil war, although his desperation to destroy a distress beacon he recognises as being Trion in origin, and his reluctance to contact his own people to save the people of Sarn indicate that there were severe penalties for him escaping his exile. It can be reasonably assumed he was an active member of the military, as he was assigned the rank and serial number of "Junior Ensign Commander Vislor Turlough. VTEC9/12/44". His mother was killed during the civil war, and his younger brother Malkon and father exiled to the abandoned colony planet of Sarn, whilst Turlough himself was exiled to 20th Century Earth.
On Earth he lived as a human schoolboy, hiding his alien origins and attending Brendon Public School, Turlough was under the supervision of a Custodian masquerading as a solicitor in Chancery Lane. He was contacted by the Black Guardian, who offered him his freedom in exchange for the death of the Doctor. Turlough subsequently ingratiated himself with the Doctor as his companions Nyssa and Tegan Jovanka, assisting in resolving a time paradox, after which he was invited to join the Doctor in his travels.
