From Tardis Wiki, the free Doctor Who reference
Sir Bron of Westhold was a knight on the planet Avalon. He helped save the First Doctor, Ian Chesterton, Barbara Wright and Susan from a fire-breathing dragon when the TARDIS locked them out. When Captain Shannon shot Jen Komati for giving the Helm to Ian, Sir Bron killed Shannon. (PROSE: The Sorcerer's Apprentice)
