Liam was a young boy, specifically a male human child, who originated from the planet known as Hetzal Prime. The Jedi Knight Vernestra Rwoh estimated his age to be around ten or eleven years. In the year 230 BBY, Liam's life took a turn when he was seized by the Nihil Tempest, commanded by the Quarren named Kara Xoo. He was subsequently transported to the planet Dalna aboard Xoo's starship, the Poisoned Barb. Upon their arrival on Dalna, Liam, together with two other abducted children, Petri, an Umbaran, and Krylind, a Kage, were handed over to the Nihil pirate Squib to become members of his strike force. Ultimately, Liam managed to break free from the Nihil's grasp and was discovered by Rwoh and Jedi Master Nyla Quinn, to whom he recounted the details of his ordeal. Subsequently, he was brought to the Dalna temple and left there under the care of Honesty Weft and Sha'nai Plouth.
