Garron
From Tardis Wiki, the free Doctor Who reference
Garron was an Earth con-artist originally from Hackneywick, Somerset. He was forced to flee Earth because he refused to sell the Sydney Opera House to a rich Arab. He and his younger assistant, Unstoffe, embarked on a career as galactic con men, selling planets to unsuspected victims. Garron tried selling Ribos to the Graff Vynda-K using a lump of jethrik, which turned out to be the first segment to Key to Time. When the Graff found out the truth, Garron and the Fourth Doctor were forced to join forces. Garron eventually ended up with the Graff's spaceship, filled with eighteen years of plunder.
