Council of First Knowledge / Legends The Council of First Knowledge was one of the four Jedi Councils of the Jedi Order in operation during the rule of the Galactic Republic . The Council of First Knowledge met in the Council Chambers atop the northwest tower of the Jedi Temple on Coruscant . Overview . The Council of First Knowledge was made up of five Masters selected to oversee the Jedi academy and the proliferation of knowledge and its storage in the Temple Archives . Additionally , the Council personally accepted the responsibility of eradicating any trace of Sith teachings and their artifacts throughout the galaxy . Meeting in the circular Council Chamber at the Jedi Temple , membership on the Council was granted through appointment after a vote of all members . A single permanent member sat for life or until he stepped down , and was known as the Caretaker of First Knowledge for this Jedi personally oversaw the protection of the Holocron Chamber located in the spire . The other four Masters rotated out after serving a five year term . Members of the Council often served on one of the other Councils simultaneously , or had retired from the High Council and retained their membership . Maintaining the academy went hand in hand with preserving the knowledge banks at the Temple ; if the base of knowledge did not constantly grow , the academy could not evolve and progress . Having direct oversight of the Librarian ' s Assembly , the Archives were presided over by a Chief Librarian who sometimes sat on the Council themselves . Members of the Council were granted access to the Holocron Vaults located within the Archives , a highly secured set of chambers used to protect the ancient holocrons and their secrets . While working with Jedi Initiate s ' schooling , the Council was not inaccessible to older Jedi needing a different perspective on a dilemma . The Council could be queried for assistance on troubling topics that needed analysis by individuals who had experienced many missions and problems in their lifetimes ; members of this Council were often of long - lived species , though this was by no means a requirement . Following the New Sith Wars , the Council dedicated itself and its shadow agents to the recovery of Sith artifacts . Deeming the possession of such material illegal , agents of the Council were sent out to virtually eradicate all traces of the Sith . They were responsible for the near elimination of Darth Andeddu from all text found within the Republic . Agents serving the Council worked primarily in the Tower of First Knowledge , consulting holocrons and making use of specialized chambers to seek out dark side activity . During the years in which this activity was concentrated , Knights working for the Council included many Jedi including Medd Tandar , Ma ' ya , Pendo , Winnoa , and Set Harth . Before turning to the dark side , Harth stole several of the artifacts that the Order sent him to retrieve , hiding them away in his estate on Nal Hutta . During the end of the Republic ' s Golden Age , it successfully resolved the E9D8 Rebellion . The earliest known members of the Council include the Ithorian Obba and Human Restelly Quist , the latter of which served as Caretaker and Chief Librarian simultaneously . Centuries later the rugged and scarred Lannik , Master Even Piell retired from his duties on the High Council and opted to sit on the Council of First Knowledge during the Clone Wars . While history is foggy on which Council Master T ' un was a member of , his position as Curator of Records suggests he may have indeed sat on the First Knowledge Council . The Council of First Knowledge existed nearly continuously throughout the history of the Order , right up until the end of the Clone Wars when the Republic was dissolved and reorganized into the Galactic Empire . With a Dark Lord of the Sith at the helm of the Grand Army of the Republic , the Council was caught unaware when Supreme Chancellor Palpatine issued Order 66 and began the Great Jedi Purge . Following the of the Jedi Temple , the members of the Council were hunted down and killed or else fled into self - imposed exile .
