Her father, Ezral, was the chief engineer of the ship which crashed during an ion storm. She was a child when the accident happened. Her father blamed himself for the accident. A holographic crew was eventually created for her companionship in 2131.
When the crew of the Enterprise 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 involved with Commander Tucker. When the crew becomes suspicious of the circumstances of the crash, they were attacked by the holographic Kantare. She would take the holograms off line and tell the crew of her father's ruse. She would eventually leave the planet with her father. (ENT: "Oasis")
