|Mission to Qiaxx|
- "Dequc is a Jeodu who is seeking to revive Black Sun. He calls his organization Black Nebula."
Shortly before the Battle of Endor, Emperor's Hand Mara Jade was tasked by Emperor Palpatine to eliminate the leader of the Black Nebula criminal organization, Dequc. She failed her mission and was not able to pursue it due to the death of her master.
After her evasion from Coruscant, Mara Jade travelled to the planet Phorliss in order to begin a new life. Calling herself Chiara Lorn, she begins working as a waitress in a cantina. However she was soon caught up by her past. Black Nebula goons tried to shakedown bartender Gorb Drig, and end up murdering him. Enraged at the men, she ignited her lightsaber and slaughters the goons. She took Drig's money to use in her newfound mission: revenge on Dequc and Black Nebula.
Mara Jade made her way to the Bubble Cliffs of Qiaxx, where Dequc has moved his operations. In a casino, she uses the Force to win enough money to gain attention to herself, posing as Baroness Paltonae. Jade was taken to see Lord Allic, who accuses her of cheating. She pretended that a small device she had concocted has allowed her to win, and Allic arranged for her to meet Dequc, so he might purchase some of the devices. After the meeting with Allic, she scouted the place where she will meet with Dequc.
The next day, Mara Jade was being taken to the meeting when she caused a disturbance with the Force which allows her to stash her lightsaber on a floating light. She was then recognized by Captain Strok, her old Imperial liaison on Svivren, but managed to knock him out and accuse him of being an Imperial spy before he can reveal her identity. Next Mara was taken to Dequc, to whom she gives a datapad of false information. She was then given a tour of the Black Nebula facilities, giving her a layout of the base. During her tour, she found Strok once again but was forced to kill the man. Dequc's forces heard the shot and pursued her, while she managed to use the Force to retrieve her lightsaber and eliminate the guards.
Mara Jade eventually found a bust of Prince Xizor's head and rigs it with her lightsaber inside. When she was finally caught, she pretended to be a thief stealing the bust. Once she was taken to Dequc, she telled him she was stealing it because it was also Xizor's own treasure map. When Dequc tried to investigate the bust, she activated the lightsaber, which ignited and stabed Dequc through the head. After have killed some other guards, Mara discovered Dequc's secret passage and escaped with Dequc's personal yacht.
