Jilka Zan Zentis was a Human female employed within the Treasury office of the Galactic Republic, specifically in Corporate Tax Enforcement, where she befriended and collaborated with Besany Wennen. Seeking a chance to double date, she aided Besany, whom she nicknamed "Bez," in locating details concerning Dhannut Logistics; Bez initially intended to match her with Fi Skirata, an arrangement disrupted when Fi sustained serious injuries during the Battle of Gaftikar.
While the Republic Treasury Audit Division was under scrutiny, the Gurlanin named Valaqil tried to shift the focus away from Besany by fabricating evidence. This evidence falsely implicated Jilka in the unlawful access of confidential data, leading to her apprehension by Republic Domestic Security.
Subsequently, Wad'e Tay'haai, Walon Vau, and Ordo orchestrated Jilka's liberation by seizing her prison transport while it was airborne, compelling it to make an emergency landing. Consequently, she became an outlaw sought by the Republic, with "wanted" notices displayed in cantinas throughout Coruscant. She was compelled to seek refuge alongside Besany and Ordo. Later, she relocated to Kyrimorut on Mandalore with Clan Skirata and began a love affair with Corr, a former clone commando.
