The Vipod Mor was controlled by a computer, which ran most of the ship. Due to a technical error, the computer developed a second personality. This second personality, seeing all the records of destruction and war in the galaxy, decided to do something about it. She planned to send the Vipod Mor back in time, changing all history for the better. Though she knew something of time travel, she required the knowledge of a Time Lord. To lure one, she brought a Maston from the past, knowing it would cause ripples in time.
