The Magician


 * You may be looking for the comic story of the same name.

A mysterious Time Lord, the Magician (formerly also known as Magus or Pagad), aided Turlough after the latter's return to his home planet of Trion. The Magician appeared as a young man in his twenties and had a strikingly whimsical personality. (TC: Turlough and the Earthlink Dilemma)


 * Though clearly willing and able to break the Time Lord's non-interference policy, we do not know whether the Magician worked as a renegade or officially, or who, if anyone, may have employed him.
