- "You're nuts, Jori."
"Yeah, like Granddad."
- ―Ben and Jori
Jori was presumably born on Coruscant, the grandson of Erv Lekauf who served under Darth Vader's command. He looked up to his grandfather more so than he did his own parents. Jori opted to follow in his grandfather’s footsteps and became a Corporal in the Galactic Alliance Guard, serving under Vader’s own grandson, Jacen Solo. Jori was fiercely loyal to Solo, though at times, he often questioned the nature of his decisions.
During one GAG raid on Coruscant, Lekauf befriended Ben Skywalker, Jacen’s cousin and informal apprentice. Lekauf offered to help Ben get over his first combat kill. They grew very close as Ben considered him to be one of his best friends.
Shortly after being commissioned Lieutenant, Jori was tasked with leading a small group of GAG personnel to Vulpter, where they were to monitor the meeting between Prime Minister Dur Gejjen and Chief of State Cal Omas. To prepare Ben for his role in the mission, Jori insisted on having a hand in Ben's combat training. Within a day, he managed to turn Skywalker into an efficient sniper, though the boy had his doubts about killing Gejjen in cold blood. Although their mission was a success, it was not a clean getaway; as Jori and Ben tried to escape security locked down the entire spaceport. Realizing that they would be caught, Lekauf took the sniper rifle from Ben, used a hostage to bluff his way out of the terminal (all the while shouting that he was a Corellian patriot opposed to the GA), and then managed to board their ship. Jori then self-destructed the ship so that security would believe the killer was already dead and Ben would go free.
