"The Archives. The library. The first hall—history of the Republic, chronicles of the Jedi going back over thousands of years. Their protector—Master Jocasta Nu."
Sha Koon

Jocasta Nu was the Chief Librarian of the Jedi Archives at the time of the Clone Wars with a penchant for being a bit overconfident in the completeness of her Archives. Her patterned robes bore the symbols of the Ansata, representing her devotion to knowledge and learning.

During her career, Jocasta trained many Padawans, including the future Emperor's Hand, Jerec, Olee Starstone, whom she tutored in the years prior to the Clone Wars, and Jin-Lo Rayce, founder of the Agents of Ossus.



"There is more knowledge here than anywhere else in the galaxy."
―Jocasta Nu, boasting about the Jedi Archives

As a young Jedi Knight, Jocasta served as an archaeologist for the Jedi ExplorCorps and for decades after her service.

Some time prior to 49 BBY,[1] Jocasta Nu stepped down after spending ten years as a member of the Jedi Council. She took up the mantle of Librarian and served as Archives Director for over thirty years. She knew Count Dooku quite well, and proclaimed him to be one of the greatest Jedi of all time.

During her position of Chief Librarian, she gathered a very precise and extensive knowledge of the galaxy. She often gave advice to Jedi Knights who were looking for information about the planets they were sent to on a mission. During these years, her confidence in the Archives was whole, claiming that if something was not in the Archives, then it did not exist. To her embarrassment, this statement was belied when Obi-Wan Kenobi was unable to find Kamino in the Archives since it took a child student under Yoda's instruction to suggest the obvious: that the records were tampered with to hide Kamino's existence.

Jocasta Nu familiarizes Ahsoka Tano with the library

Around 22 BBY,[2] the Jedi High Council assigned Jedi Padawan Ahsoka Tano as a Jedi Archives guard under Nu, as punishment for her actions during the First Battle of Felucia. Nu gladly accepted the help, and was present in the library with Tano when Cato Parasitti infiltrated under the guise of deceased Jedi Master Ord Enisence. After observing Parasitti's behavior and becoming suspicious, Nu began to question the bounty hunter, only to be knocked out. The Clawdite promptly stole Nu's guise and her lightsaber, and continued to lead Cad Bane into the holocron vault. She was defeated by Tano shortly after, and Nu regained consciousness with no major injuries to speak of.[3]

Jocasta Nu is killed by Darth Vader.

During Operation: Knightfall in 19 BBY, Jocasta told her last Padawan, Jin-Lo Rayce, to flee the Temple through underground passages into the Coruscant underbelly. She would remain within the Archives, where she would confront Darth Vader, wielding her blue lightsaber. Denying him access to the Temple beacon, the Dark Lord lifted her with the Force and impaled Jocasta through the chest, killing her instantly. Jocasta's body was found by Obi-Wan Kenobi and Yoda when they returned to Coruscant.

When the Galactic Empire emerged, official records compiled by Sate Pestage stated that Jocasta Nu was executed for harboring information that threatened the Empire and its citizens.

Personality and traits

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 library and often got affronted if someone suggested that her archives were incomplete. This was shown when Obi-Wan Kenobi suggested that her archives were incomplete and she indignantly replied that if something didn't appear in her records it didn't exist.

Although a little too proud of her library, Jocasta was friendly and helpful, but most people knew better than to get on the wrong side of her. Prior to the Clone Wars, she knew Count Dooku quite well, believing him to be one of the greatest Jedi of all time.

Powers and abilities

"You may have Madam Jocasta's shape but not her skills."
―Ahsoka Tano after defeating Cato Parasitti

Jocasta Nu was trained as a Jedi consular but there is little actual knowledge on her Force powers and lightsaber combat skills, though it was known she wielded a blue lightsaber in 22 BBY. She was a member of the Jedi Council for ten years but whether she got onto the Council through skill or through wisdom is unconfirmed.

Behind the scenes

The character of Jocasta Nu was created for the Star Wars Episode II: Attack of the Clones, where she was played by Alethea McGrath, an actress who also voiced her in the Revenge of the Sith video game, in which she is killed in a cut-scene by Darth Vader. She is voiced by Flo DiRe in Star Wars: The Clone Wars TV series.[1]

Jocasta Nu's robes are of the Jedi historian design, one which is similar to Atris' from Star Wars: Knights of the Old Republic II: The Sith Lords.

"Jocasta" is a Latinized form of the Greek name Ιοκάστη, which is of unknown meaning. In Greek mythology, Jocasta is the mother and wife of Oedipus. Further Greek influence may be seen in her name "Nu", a letter in the Greek alphabet which also occurs in the so-called in-universe Secondary alternate alphabet. Interestingly, the name of the actor who played the character is also of Greek origin: Alethea, from the word meaning "truth" in Greek (aletheia).[4]
