Jedi Temple Detention Center The Detention Center was a series of secure chambers located in the southwest quarter of the Jedi Temple on Coruscant . Established millennia before the Clone Wars to house captured Sith and their creatures , the Center would later be used to hold insolent members of the Jedi Order from minor to major infractions . While the chambers would be destroyed during the Great Jedi Purge at the rise of the Galactic Empire , the Center would be reconstructed in the New Jedi Temple circa 35 ABY . History . Erected in some form shortly after the establishment of the Order ' s permanent presence on Coruscant , the Detention Center would hold prisoners during the Great Sith War and the Jedi Civil War . While the Detention Center would be abandoned following the First Jedi Purge of 3954 BBY , the Order would reclaim the Temple soon after and hold it for several more centuries . The Detention Center again fell to the Sith when the resurgent Empire returned from the Unknown Regions to sack the capital and oust the Jedi from the Temple . The damage was too extensive to restore immediately , as the Galactic Senate too overstretched to be able to raise taxes to repair the Temple for several years . However , the Temple was eventually rebuilt and the Detention Center was erected anew . After the New Sith Wars and the supposed extinction of the Sith the Detention Center would come to hold more non - Force - sensitive prisoners all of which would typically be turned over to the Coruscant Security Force after being debriefed and interrogated . During the Clone Wars criminal Car Affa was apprehended by Jedi Knight Anakin Skywalker and brought to the Detention Center for questioning by the Order ' s interrogators . At the end of the war in 19 BBY the last Dark Lord of the Sith Darth Sidious , in his alter ego of Supreme Chancellor Palpatine , ordered the Temple routed of all Jedi by the Grand Army of the Republic . Led by Darth Vader , the 501st Legion stormed the complex and carried out Sidious ' s to the letter . The ancient edifice would lay abandoned throughout the Galactic Civil War , falling apart over the decades . After Sidious was killed at the Battle of Endor and the Imperial forces were driven from Coruscant , the New Jedi Order retook the Temple for a time ; though the Detention center went unused . With the Yuuzhan Vong War , the Temple was damaged beyond repair and left to fall apart . Following the war the newly formed Galactic Alliance ' s Chief of State ordered the Temple rebuilt as a gift to the heroic New Jedi Order . Using blueprints recovered from the old Jedi Archives , the Reconstruction Authority erected a new Temple over the old foundations . Restored , the Detention Center would come to house Padawan ' s that misbehaved at the Temple and Dark Jedi . Following the Dark Nest Crisis , the Order decided to house rogue Jedi Raynar Thul here , after he had been severely traumatized during his stay with the Killik s . While healing the young Knight the Jedi healer s sealed Thul in the Center ' s Asylum Block , the collection of rooms designed to house seriously neurologically damaged individuals . During the Second Galactic Civil War in 41 ABY , Ben Skywalker infiltrated the laundry chute in the fourth level training center ' s changing room on the instruction of Apprentice Seha Dorvald . Dorvald had told him that she was relaying these instructions from Skywalker ' s Master , Jacen Solo . Skywalker was hesitant on entering the shaft , as rumor persisted that they were equipped to dump any living beings in the shaft into the Detention Center . Two years later , the Asylum Block would become home to the Knights who were stricken with an enigmatic madness . As more Knights were put in the chambers , Raynar Thul was finally able to reintegrate into the Temple community . Following his capture by the members of Darkmeld , Knight Seff Hellin was locked away here so as to be studied more carefully by Chief Healer Cilghal . Shortly after Hellin was secured here , fellow Knights Natua Wan , Yaqeel Saav ' etu , and Bazel Warv were all forced into the Block after going insane . However , they did not stay long as increased pressure on the Order to turn them over to Chief Natasi Daala forced the Jedi to act . Knight Leia Organa Solo kidnapped the insane Jedi without the knowledge of the Jedi High Council and transported them to the Jedi academy in the Transitory Mists . Layout . Located in the southwest quarter of the Temple , the Detention Center was a large area established on the level above the Room of a Thousand Fountains and below the Halls of Healing . Made up of several different specialized facilities and blocks , the Detention Center was a huge complex . The exterior chambers were lit with a harsh orange light and were used to house Sith , Dark Jedi , and their Sithspawn . Designed to withstand the powers of the dark side of the Force , most of the chamber was reinforced with Force and lightsaber resistant metals as well as being encased in ray shield cover . Less secure rooms , simple holding chambers were built to hold non - Force - sensitives , as well as Jedi apprentices that had broken Temple rules and needed to be held until a ranking Jedi could issue a just punishment . The laundry shafts in the Temple were designed to capture any living beings that entered the chute and deposit them within a holding room in the Center . The Asylum Block of the Temple Detention Center was a comfortable two - story transparisteel cube located in its own blue - lit atrium , completely encased in a barrier field . The entire structure was surrounded by olbio tree s which were home to the Force - negating ysalamir i , a feature that cost the Order quite a large sum of credits . Upon approach , a small golden access point would form in the barrier field , admitting Jedi into the facility after a retinal scan was performed . A path between two rows of olbio trees led to a control room that contained equipment and security controls used to maintain the entire facility . A commissary was located within the block , access to which was attainable only if a patient was escorted by a healer . A turbolift ran the height of the Block , granting access to the second story catwalk . Each of the cells were designed with comfort in mind , aside from the lack of privacy afforded by the transparisteel walls ; though the room ' s refreshers were located behind a privacy curtain . Equipped with bolted - down flowform seating and holograhic entertainment centers in the main living area and a small bed in each resting chamber , the cells were more or less apartments whose tenants could not leave . Each room ' s door was magnetically sealed , making it impervious to any tricks that a Force - impaired captive might employ . Electronic speakers were installed on the catwalk - side of the cells so that anything the patients might say would be broadcast to the healer standing watch .
