Chu ' unthor The Chu ' unthor ( the Cerean word for " academy " ) was a praxeum ship designed by Cerean Jedi Fin - So - Rowan and Human Jedi Ivixa Delbaeth . The ship was built in orbit around the planet Abhean by Republic Fleet Systems circa 500 BBY . History . Its primary function was as a spacefaring academy for groups of Jedi apprentices , and it operated under the command of a number of Jedi Masters before crashing on the planet Dathomir in 230 BBY . The Academy aboard the " Chu ' unthor " produced several powerful Jedi , including Easal Mar and Ainvar ul - Esca — the latter later pursued a mission of diplomacy and exploration , negotiating a truce on Qualtrough , and making first contact with the Elathan . The ship was quite large : it measured two kilometers long , one kilometer wide , and at least forty meters tall . A command pinnacle in the center of the ship housed the majority of the non - Jedi crew , with the sublight and hyperdrive engine array mounted directly aft . The " Chu ' unthor " could accommodate 10 , 000 Jedi students , and contained hundreds of exercise and lightsaber - sparring rooms to hone each student ' s concentration , form , and body . Workshops were provided for the construction and maintenance of lightsabers , while meditation chambers gave students and masters alike a place to contemplate the nature of the Force and further their mental discipline . A medical wing contained hundreds of rooms used to teach Jedi healing arts to young students , both for use in the aftermath of battle or accident and to aid the physically or mentally impaired . The ship contained its own extensive library with texts covering the myriad of Jedi teachings , advanced and theoretical science tomes , historical annals , literature from across the galaxy , and encyclopedias covering the galaxy ' s languages , art , and culture . The ship had a relatively small crew , due to much of the ship being automated and run by droids . Most of the crew were Republic Navy veterans . A number of non - Jedi research organizations , including the University of Sanbra , had branches located on the vessel . To alleviate the sense of confinement and banality that can be experienced while traveling for long durations in a spaceship , the " Chu ' unthor " had wide corridors with high ceilings , while many rooms had transparisteel domes or expansive viewports . The effect created was an environment very much like the Great Temple on Coruscant , rather than that of a simple starship . Classes were often held within these rooms , open to the stars , reminding the Padawans that a Jedi was obligated to serve the galaxy at large , rather than to use his or her gifts towards the pursuit of selfish ends . In the year 230 BBY , the service of the " Chu ' unthor " was cut tragically short when it crashed into the exile world of Dathomir , home to Force " witches " descended from the fallen Jedi , Allya . The damaged " Chu ' unthor " was surrounded by the witches on their rancor mounts . A group of Jedi ( including Yoda , Gra ' aton , and Vulatan ) were sent to attempt a rescue of the vessel ' s crew and passengers , but were stopped by the Witches of Dathomir . After Yoda saved the life of Rell , a young witch , the two were able to negotiate a settlement . The " Chu ' unthor " and its library would be abandoned on Dathomir , but the Jedi were free to leave . Yoda asked Rell to hide the ship ' s reader disks until a Jedi Knight came , who would free her world from the Nightsisters , the witches who had enveloped themselves in the dark side of the Force . During the Clone Wars , a second ship by the name " Chu ' unthor " served as a mobile academy headed by Master Djinn Altis . Several centuries after the first " Chu ' unthor " crashed on Dathomir , in 8 ABY , Luke Skywalker came to the planet , fulfilling Yoda ' s prophecy . He had discovered records mentioning the rescue mission undertaken centuries earlier while visiting the planet Toola , and arrived in the company of Prince Isolder of the Hapes Consortium , who was searching for Han Solo and the kidnapped Princess Leia Organa Solo . After locating Leia through the Force , Luke and Isolder discovered the " Chu ' unthor " , and began to understand the purpose of the rescue mission . After defeating the Nightsisters and Warlord Zsinj , Luke was given records from the " Chu ' unthor " , which he added to his collection for the Jedi Praxeum he later established on Yavin 4 . Several years later , the " Chu ' unthor " was ransacked by Imperial forces under the command of General Vit , as part of Project Nightsaber . Legacy . During the Clone Wars , a second ship by the name " Chu ' unthor " served as a mobile academy headed by Master Djinn Altis . The record on data tapes found in the wreck of the ship contained information about the training of Jedi . Later the data tapes were taken to the new Jedi library on Ossus . In 40 ABY , nearly all of the Jedi datatape s in the possession of the New Jedi Order came from the Chu ' unthor .
