Gold Usher (The Invasion of Time)

The Gold Usher invested the Fourth Doctor as President of the Supreme Council of the Time Lords of Gallifrey. He handed the Doctor the Rod of Rassilon and the Sash of Rassilon and introduced his mind to the Matrix.

When the Matrix appeared to reject the Doctor and attack him, the Gold Usher argued the legality of this induction with Chancellor Borusa. (TV: The Invasion of Time)
