Corwyn
From Tardis Wiki, the free Doctor Who reference
Corwyn was the subcommander of the ship that took Prince Kylo Sorsha to Sharnax. When Shira died he took command, and told the Fifth Doctor the dangers awaiting them on Sharnax. He wanted peace. He often didn't listen to the Doctor's advice. He was a saboteur. It was revenge for the attack on his wife. (AUDIO: The Burning Prince)
