Lohjoy, a Ho'Din engineer, worked on the starship Omen in 5000 BBY. This was the time when the Great Hyperspace War began between the Galactic Republic and the Sith Empire. During that year, the Omen and Harbinger, both Sith dreadnaughts, were transporting Lignan crystals, which could amplify lightsabers, to Sith Lord Naga Sadow. A Jedi starfighter ambushed the two ships over Phaegon III, a planet in the Outer Rim. While Lohjoy was sending a hologram to Yaru Korsin, the commander of the Omen, an explosion occurred. Her snake-like Ho'Din hair caught fire, and she was killed when the hull was breached. Korsin remembered Lohjoy as being both honest and careful.
John Jackson Miller included Lohjoy in his 2009 eBook, Lost Tribe of the Sith: Precipice.
