Her father, Ezral, was the chief engineer of the ship which crashed on an unidentified planet following an ion storm in 2129. She was a child when the accident happened – Trip Tucker speculated that she was five or six when the ship crashed, suggesting she as born around 2123. Her father blamed himself for the accident, as he had abandoned his post in engineering in order to save her, reasoning at the time that his team might be able to handle the repair work whereas he knew that Liana would be killed if the ship crashed while she was in their quarters near the bottom of the ship. A holographic crew was eventually created for her companionship in 2131.
When the crew of Enterprise NX-01 landed on the planet, she met them. Liana wanted to know more about the ship and the Humans homeworld even though her father disapproved. She became romantically interested in Commander Tucker. When the crew becomes suspicious of the circumstances of the crash, they were attacked by the holographic Kantare. Liana took the holograms off line and told the crew of her father's ruse. Later, she planned to eventually leave the planet with her father once the holographic crew had got the ship operational, and hoped keenly that she and Trip would meet again. (ENT: "Oasis")
