Throughout her career , she had numerous confrontations with the Jedi Knights Qui - Gon Jinn , Obi - Wan Kenobi , and Anakin Skywalker . During the Clone Wars , she was a leading scientist working for the Confederacy of Independent Systems . When the war had ended , she had been drafted into working for the new Galactic Empire . Biography . Early career . At the beginning of her career , Jenna Zan Arbor was a famed scientist and the head of Arbor Industries . She was known for saving a planet from a pandemic after creating a vaccine for a deadly virus . Zan Arbor was also known to help planets with little technology such as Melasaton overcome their burdens . However , nobody knew that she actually started the problems in the first place , to gain credits and improve her reputation . Force experiments . Zan Arbor became interested in how the Force worked and began conducting experiments . She had connections to the senator of Belasco , Uta S ' orn who kept her dark deeds quiet in the Galactic Senate . Unbeknownst to Senator S ' orn , her son Ren , who was Force - sensitive ( although his mother had taken him away from the Jedi Order when she was unable to cope with losing him ) was being studied by Zan Arbor . These experiments lead to Ren ' s death , something Zan Arbor didn ' t expect . Feeling somewhat remorseful , she felt she needed a subject stronger in the Force , so she hired a bounty hunter , Ona Nobis , to capture the " retired " Jedi Master Noor R ' aya and bring him to her research facility on Simpla - 12 . Then , weeks later , another Jedi named Qui - Gon Jinn was knocked out by Nobis in the Cascardi Mountains on Duneeden . He was taken to the laboratory , where Zan Arbor tortured him to the point of near death . However , Qui - Gon was rescued by Obi - Wan Kenobi , along with Astri Oddo , who was disguised as Ona Nobis . Yet Zan Arbor warned the Jedi that she had another in custody — Noor R ' aya — and threatened to inject him with poison should Qui - Gon leave the building . She killed her assistant , Nil , as he was a liability . Zan Arbor then made plans to leave the planet , contacting Cholly , Weez and Tup , who were droid dealers to arrange shipment of battle droids . But the trio were helping Obi - Wan , Siri Tachi and Adi Gallia get into her lab . Belasco . With the droids all destroyed , Zan Arbor escaped the planet with Noor . She fled to Belasco , where she engineered a virus from natural waterborne organisms on the planet . She planned to infect the populace through their water supply , designing the bacteria to proliferate if threatened . With S ' orn ' s help , she was able to infiltrate the containment facilities to introduce the bacteria . The Jedi caught up to her , with the data to cure Belasco . As Qui - Gon trapped her under a tapestry , she deeply regretted that she didn ' t kill him when she had the chance . Both Zan Arbor and Uta S ' orn were sent to a penal colony for life . The solution for the bacteria Zan Arbor introduced was found on her datapad and the water was fixed . Galactic criminal . Around 25 BBY , Zan Arbor somehow escaped the penal colony . She settled on the planet Vanqor and began perfecting a drug known as the Zone of Self - Containment . With this drug , she was able to capture Anakin Skywalker and many other innocent people ; however , she was forced to flee Vanqor when Obi - Wan Kenobi , Siri Tachi and Ferus Olin came to rescue Anakin . Fleeing Vanqor , Zan Arbor teamed up with Granta Omega who agreed to fund her next project . She went into hiding on Romin , under the protection of Roy Teda and her Phlog bodyguard Hue . When Teda was overthrown , the Jedi came to capture them , but they escaped yet again . In 24 BBY , Zan Arbor then constructed the Blackwater Systems facility on Falleen to create machines that would be used to spread the Zone of Self - Containment . The Jedi once again foiled her plot and she was forced to destroy the facility . The Jedi chased her to Coruscant , where she and Granta Omega orchestrated a failed attempt to assassinate Supreme Chancellor Palpatine , and finally to Korriban , where she and Omega were cornered by the Jedi in the 23 BBY . When the Jedi killed Omega , Zan Arbor fled . She went into hiding and went unnoticed by both the Jedi and the Republic . That same year , when Count Dooku publicly declared the formation of the Confederacy of Independent Systems , Zan Arbor was hired to be one of their leading scientists . The Clone Wars . Now a scientist for the Separatists , Zan Arbor created devastating agents of biological warfare . A few months before the Battle of Geonosis , she worked with Arkanian genetic researchers to create the stone mites , insects that could devour entire buildings in mere hours . These stone mites were unleashed on a number of worlds . Two months into the Clone Wars , Zan Arbor successfully perfected a deadly gas poison that was used to wipe out the entire Gungan colony on the Naboo moon of Ohma - D ' un . A form of this same gas was incorporated into the defense mechanism of Viceroy Nute Gunray ' s mechno - chair . Early Empire . A year after Order 66 was carried out , Zan Arbor was spotted on Korriban by Ferus Olin and Trever Flume followed by a high - ranking Imperial Officer . She commanded the officer to bring her to the Valley of the Dark Lords . Later , on Bellassa , Olin discovered evidence possibly linking her to a secret Imperial project . Zan Arbor was working with scientists who had been forcibly taken from their homeworlds to help with this operation , though weapons systems weren ' t in her repertoire . She had been working to create a memory serum that would completely remove specific unpleasant memories . Scientist Linna Naltree was with her when the Sith Lord Darth Vader came to call for the serum , seeking to eliminate his memory of Padmé Amidala . In return for her services , she would have an apartment in 500 Republica , a personal visit to and starship designed for her by Raith Sienar , and a high level security pass . After Vader left , Zan Arbor and her assistant ran into fugitives Trever Flume and Ry - Gaul . As the two attacked the scientist , Linna administered the serum via syringe to Zan Arbor , wiping her memory slowly . As she screamed over her fading formulas and fifty years of work , Trevor Flume destroyed her personal datapad , eliminating the threat of Jenna Zan Arbor once and for all . Now an empty shell of her former self , Zan Arbor was left with no identity and a vague sense that she had once been a brilliant genius . Later , when Vader visited Zan Arbor after she failed to respond to any of his messages , he found out what happened to her and killed her in a flash of anger .
