Lord Marsten was the final official governor of Monitor, a city on the Serpent Isle in Ultima VII Part Two. A Knight of the city, Marsten was the leader of the Leopard Command. In the final year of the city, it was Marsten's turn to be in control of the city, thus his title of Lord. Marsten, though short in stature, was a fierce and effective fighter. He was bedmates with Astrid, the current Champion Knight of the city. He said they were bedmates as opposed to lovers, saying that their relationship was one of comrades and arms and the physical intimacy was just that (despite the fact he did harbor strong feelings for her).
