Biography
She served aboard The Lorelei cargo spaceship. She encountered the Seventh Doctor shortly before a group of Voc robots began to attack the crew of her ship. She helped the Doctor to discover that the Voc robots were not behind the attacks, and found that the ship's security chief, Farel dressed as a robot when instigating an attack. Liv and the Doctor then prevented Farel from crashing the Lorelei into Ventalis. Liv stayed behind on Ventalis after the Doctor had departed. (AUDIO: Robophobia)

Liv was present on Nixyce VII when the Daleks invaded. She was used by the Dalek time controller to be a source of compassion amongst the natives of Nixyce VII. (AUDIO: The Traitor)

Liv fled the Dalek invasion, and went into cryo-sleep on board the Orpheus for a thousand years. She awoke when the Orpheus had reached the edge of the universe. Liv once again met the Doctor on board the Orpheus, shortly came under attack by the Eminence, and it began to possess the crew. Liv planned on blowing herself up next to a piece of the Eminence in order to stop its plan, but was rescued by the Doctor. She promptly joined him as a companion. (AUDIO: Time's Horizon)

Liv travelled with the Doctor to London in the 1970s, where she helped the Doctor to defeat and the Eminence. After they were defeated, the Doctor made Liv stay behind in London as he had to play out the events in which Liv first met him on Nixyce VII. (AUDIO: Eyes of the Master)
