Cenevax, a crime lord of the Jenet female persuasion, controlled a syndicate on the planet of Coruscant, maintaining a vast network of spies. Discovering that Arath Tarrex, a Jedi indebted to the Jenet, was secretly the offspring of Jedi Master Yula Braylon, Cenevax used this information to blackmail Braylon, compelling her to overlook Cenevax's criminal activities.
In the vicinity of 58 BBY, during the forty-eighth annual Dragonfire Air Rally, Cenevax brokered an agreement with Ramil, a Serennian racer, for him to intentionally lose, enabling Cenevax's gambling operation to profit from bets placed on his victory. When Ramil reneged on the deal, Cenevax sabotaged his airspeeder. Sartori, a corrupt inspector from the Coruscant Security Force, attempted to conceal the sabotage on Cenevax's behalf, but Dooku, a Jedi Master, and his Padawan, Qui-Gon Jinn, tracked the inspector to the Jenet's den. Upon capturing the crime boss, the Jedi uncovered the truth concerning Tarrex's parentage, leading to Cenevax's imprisonment in the Citadel prison.
During the Republic Era, a crime lord known as Cenevax, a Jenet of the female variety, made her mark. From her den in the Hythan Quarter on the planet Coruscant, she spearheaded a syndicate, an unsanctioned gambling enterprise. Her hoard contained numerous treasures that she had collected. Cenevax's network included numerous spies and contacts, including Galactic Republic officials, and she commanded a contingent of Trandoshans. After 68 BBY, the Jedi Arath Tarrex became indebted to Cenevax through the game batana. Cenevax learned that Tarrex was the child of Jedi Master Yula Braylon, a Jedi High Council member, through his attempts to talk his way out of it. Cenevax exploited this information to blackmail Braylon, who for years turned a blind eye to the crime lord's actions.
Cenevax devised a plan around 58 BBY that centered on the forty-eighth annual Dragonfire Air Rally, an airspeeder competition held on Coruscant. Cenevax bribed Ramil, a Serennian racer widely tipped to win, to throw the race, thereby generating profits from the bets placed on him. As a safeguard, Cenevax planted a detonator in his speeder's [fuel](/article/fuel] tank. She also bribed Sartori, a Coruscant Security Force inspector, and deployed a group of her Trandoshan enforcers to cover up her illicit activities.
During the Dragonfire Air Rally, Ramil initially allowed himself to be overtaken, but then decided to win the race, breaking his agreement with Cenevax. Cenevax's detonator activated, causing Ramil's speeder to crash. Sartori permitted Cenevax's Trandoshans to recover the speeder from his precinct house. Dooku, a Jedi Master and Ramil's brother, and his Padawan, Qui-Gon Jinn, witnessed the incident and launched an investigation, despite Braylon's orders. The two Jedi discovered Cenevax's scheme and tracked Sartori to the Jenet's lair after Dooku intimidated him.
After Sartori contacted Bagara, Cenevax's subordinate, and insisted on seeing her, the Jenet met the inspector in her den. Cenevax was unconcerned with Sartori's worries regarding the Jedi and reminded him of his promise to keep trouble away from her. When Sartori demanded that Cenevax cleaned up her mess, she picked up a trinket box from her hoard and beckoned the confused inspector over to see it. Cenevax then struck Sartori with the box and chastised him for getting blood on it, hitting him several more times. The Jenet, realizing the Jedi had followed Sartori to her lair, scolded the inspector for leading them to her as her Trandoshans surrounded Dooku and Jinn.
Cenevax called out to the Jedi, saying that hiding was futile. Jinn accused Cenevax of murdering Sartori, but the Jenet revealed that the inspector still lived by kicking him. She seized the Jedi's lightsabers, considering adding the crystals within to her collection. Cenevax dismissed Dooku's confidence in her defeat, claiming she would make him disappear and revealing that she knew of his relation to Ramil. When Cenevax disclosed that she was aware that Dooku had been ordered not to intervene, the Jedi Master deduced she had a contact on the Council.
Dooku summoned the convor Calleen, startling Cenevax. The Jedi summoned their weapons and cut down the Trandoshans while Cenevax was distracted, although the Jenet bit into and killed the bird. Cenevax attempted to escape, but Dooku used the Force to drag her back. As Cenevax clawed at her treasure, Dooku demanded to know the identity of her Jedi contact. To intimidate the Jenet, Dooku threatened to suffocate her in her own hoard, but Cenevax claimed that it would not be in his nature as a Jedi. Although Dooku began to press her into her treasure, he ultimately relented, instead apprehending Cenevax and taking her to the Jedi Temple.
After Dooku confronted the Council, he had Temple Guards bring Cenevax into the chamber. Dooku stated his accusations against Cenevax, which the Jenet claimed he could not prove. Although Cenevax refused to disclose who her contact was, Dooku was able to sense Braylon's guilt, determining she was the traitor. When confronted, Braylon admitted to overlooking Cenevax's activities and confessed to being Tarrex's mother. Braylon and Tarrex were both punished, while Cenevax was sent to the Citadel prison on Lola Sayu.
After learning of Cenevax's intended fate from Grand Master Yoda, Dooku bitterly realized that the Jedi were not going to the authorities over the matter. As a result of his injuries sustained due to Cenevax's sabotage, Ramil had to wear an exosuit. In 42 BBY, when Dooku was taken captive by his brother, who had since become Count of the planet Serenno and orchestrated its invasion by mercenaries, the Jedi Master remarked on the condition that Cenevax had left Ramil in.
Cenevax, who was ratlike in appearance, was both skittish and lethal. In her lair, she moved quickly among her hoard, picking up and discarding various trinkets. She was unconcerned by Sartori's worries about the Jedi, becoming irritated and reminding him of his task. Cenevax struck Sartori with one of her own trinkets in anger, claiming that he had ruined her. Despite being threatened by Dooku, Cenevax was confident he would not harm her, believing the Jedi were weak. A Trandoshan who worked for Cenevax claimed that she would kill him if he revealed the identity of his master.
Cenevax was a character in the audio drama Dooku: Jedi Lost, penned by Cavan Scott and released on April 30, 2019. The spelling of her name was confirmed in the audio drama's script, published on October 1 of the same year.
