Jocasta Nu died when the 501st Legion the Jedi Temple at the end of the Clone Wars . Biography . Brought into the Jedi Order during the final decades of the Galactic Republic , it is likely Jocasta Nu was discovered by a recruiter of the Acquisition Division to be Force - sensitive around infancy before being brought to the Coruscant Jedi Temple for training . Raised in a youngling clan , she passed the trials of the Jedi academy and was eventually selected by a Master for one - on - one training . Passing the Jedi Trials , Nu pursued the path of the Consular and became a researcher specializing in the field of archaeology . Attaching herself to the Exploration Corps after consulting the Council of Reassignment , Nu traveled the galaxy gathering information for the Jedi Archives . During her journeys Nu discovered the Force - sensitive Miraluka , Jerec , and delivered him to the Temple for entrance into the academy there . Eventually Nu returned to the Temple and selected Jerec as her Padawan , passing along her own desires to learn all there was to know in the galaxy , which eventually drove him to Knighthood himself . Completing the training of a Padawan , Nu was made a Jedi Master and began to perform the duties of an archivist in the Archives . Eventually , Nu was appointed Chief Librarian of the Archives and Library and made a member of the Librarian ' s Assembly . Part of her responsibility as Chief Librarian was oversight of the Educational Corps ; she reported directly to the Reassignment Council on all matters concerning this branch of the Jedi Service Corps . During her tenure as Chief Librarian , Nu was appointed to the Jedi High Council , serving ten years on the august body before stepping down in 52 BBY . Foregoing the traditional brown robes of the Order , Nu began wearing a tunic and dress imprinted with ancient Ansata patterns , a type of dress worn by some of the most famed Jedi historians including the ancient Master Atris . Over the years , Nu came to know most of the Jedi in the Temple , becoming especially fond of Master Dooku ; she personally mourned the loss of his great idealism when he left the Order shortly following the Invasion of Naboo . Using the extensive knowledge gained in the field with the ExplorCorps , Nu continued to gather a very precise and extensive knowledge of the galaxy . Working in cooperation with the Jedi Councils , Nu was always advised of upcoming missions so that she could help prep a report for all Jedi about to depart the Temple . In 52 BBY , Nu undertook a diplomatic mission to the world of Serenno with Jedi Masters Dooku , Qui - Gon Jinn and Sifo - Dyas . At the meeting , the Jedi team met Damask Holdings Magister Hego Damask , in reality the Sith Lord Darth Plagueis . Nu took on her last Padawan , Jin - Lo Rayce sometime after the Stark Hyperspace War around 44 BBY , teaching him all of the secret passage ways in and out of the Temple . In 39 BBY , Jedi Master Qui - Gon Jinn and his Padawan Obi - Wan Kenobi were sent on a mission to Vorzyd IV . Nu provided the two Jedi with the information needed for them to complete their assignment . Over the course of her time as director of the Archives her confidence in the data stored in the stacks was whole ; claiming that if something was not in the Archives , then it did not exist . This statement was belied when Jedi Knight Obi - Wan Kenobi was unable to find the aquatic world Kamino in the Archives and suggested that the Archives were incomplete ; somewhat miffed , Madame Nu reiterated her belief that if an item was not in the Archives , it did not exist , and strode away to assist a young Padawan who had just arrived . Discovering that the files had been purged from the Archives ' data banks , the integrity of the Archives came into question much to Nu ' s embarrassment . Clone Wars . With the Clone Wars underway in 22 BBY , the High Council became increasingly concerned with protecting the Archives as more and more Jedi were called away from Coruscant to fight on the front lines . As reprimand for failing to follow orders during the First Battle of Felucia , the High Council assigned Padawan Ahsoka Tano to guard duty within the Archives . Meeting Tano in the Archives ' Rotunda , Nu familiarized the Togruta with security protocols in the Archives and around the Holocron Vaults . Putting Tano to the test , bounty hunter Cad Bane had sent Cato Parasitti into the Temple to assist in his infiltration mission . As a Clawdite , Parasitti was able to slip pass both Tano and Nu under the guise of the recently deceased Master Ord Enisence . Suspicious of Enisence ' s oddly curt behavior , Nu offered the Skrilling a gentle hand , only to be struck by the bounty hunter and rendered unconscious . Stealing Nu ' s identity , as well as her blue - bladed lightsaber , Parasitti broke through Temple security and allowed Bane to enter the Temple without much trouble . While distracting the Jedi monitoring Temple security , Parasitti was discovered by Tano to be an impostor . After a brief scuffle , Parasitti was defeated and placed under arrest , yet Bane had already successfully completed his mission to infiltrate the Vaults and escape unnoticed . Nu recovered shortly after and returned immediately to her work . Order 66 and Death . Nu remained at the Temple throughout the conflict with the Confederacy of Independent Systems , one of the highest ranking Masters to remain constantly on Coruscant . At the end of the war , she was diligently at work in the Archives when was initiated in 19 BBY . Shortly prior , she finally expressed doubt to Knight Sha Koon in the completeness of her Archives . As fighting erupted in the Temple ' s lower levels , Nu summoned her Padawan , Rayce , to the Archives and handed him several datachips with information from the Stacks uploaded to them . Ordering him to flee , she watched as Rayce departed the Temple through the secret passageways she had detailed to him over his apprenticeship . Remaining behind , she waited in the Archives until Dark Lord of the Sith Darth Vader marched through the great wooden doors flanked by several clone assassin s . Vader demanded that Nu unlock the secured Temple beacon , a demand she denied by igniting her blue lightsaber . Casually , Vader lifted the esteemed Jedi with the Force and impaled her through the chest with his own saber , killing her instantly . Ironically , during her conversation with Koon earlier that day , Nu had praised Skywalker as a hero . Flinging her body carelessly amongst the Stacks , the Sith continued to ransack the Archives while Nu ' s loyal librarians attempted to destroy all of the knowledge stored there so that it would not fall into the hands of their mortal enemies . After the fighting died down , Nu ' s body was discovered by Grand Master Yoda and Master Kenobi as they made their ways through the halls of the Temple . Her body would eventually be gathered up and her name checked off against Archives records of all active Jedi . After she was confirmed dead , her body was most likely dragged out onto the steps of the public entrance of the Temple and thrown on the makeshift pyre with all of her fallen comrades . When the Galactic Empire emerged from the ashes of the Republic , Sate Pestage compiled a statement that was to be issued to the citizens of the Empire as proof of the Jedi ' s crimes . In his fabricated report , Pestage stated that Jocasta Nu was executed for harboring information that threatened the Empire and its citizens . Personality and traits . By the time of the Clone Wars , Nu was thin , frail - looking woman with long silver hair that she wore in a tight bun . She had blue eyes and a pronounced scar running along the right side of her face . Despite her wispy appearance , Nu actually was a known firebrand among her peers , noted for her immense determination and strength . Nonetheless , younger Jedi students still attempted to push her around , trying to get the librarian to do the bulk of their research for them . However , Nu considered the Jedi Archives a tool rather than a service , and she expected all jedi to do their research by themselves , which led her to being particularly strict toward those students . If Jocasta Nu had allowed herself to have an attachment it would have been to her library . She had a trait for being a little overconfident about the amount of information in the Archives and often got affronted if someone suggested that the Stacks were incomplete . This trait was shown when Knight Obi - Wan Kenobi noted the supposed disappearance of the planet Kamino . To this she indignantly replied that if something didn ' t appear in her records it didn ' t exist . By the end of the Clone Wars , however , Jocasta Nu came to accept the fact that her Archives did not contain everything . Although a little too proud of the Archives , Nu was friendly and helpful , but most people knew better than to get on the wrong side of her . Powers and abilities . Achieving all of the basic Force skills at the academy during her younger years , Nu had pursued the studies of the Consular , perfecting her researching skills through her studies as an archaeologist of the ExplorCorps . While retired from combat missions in her later years , she still wore her lightsaber proudly as a reminder of her active years , during which she had received a thin vertical scar along her cheek . When ignited her saber would emit a shimmering blue blade , which was somewhat unusual as Jedi Consulars typically carried green - bladed lightsabers , used sparingly but with skill . Equipment . During the course of her career , Jocasta Nu wielded at least two different lightsabers , one of which had a green blade , and another with a blue blade . In her late years , she wore robes inscribed with a traditional Ansata pattern , which symbolized her love of knowledge and learning . Behind the scenes .
