Jedi Temple Lake Level The Lake Level was a five story facility located within the walls of the Jedi Temple on Coruscant . Used as a meditative retreat , the lake and beach area was a place of quiet contemplation and reflection . History . Built within the Temple Ziggurat , this vast chamber was destroyed and rebuilt several times in the Temple ' s long history , seeing completion in 1000 BBY under the Galactic Republic . In 44 BBY , a string of robberies broke out in the Temple and the Jedi High Council assigned Jedi Masters Tahl and Qui - Gon Jinn to lead the investigation . After Jinn ' s quarters had been violated , the blind Master Tahl was able to recognize a foreign scent from Jinn ' s room as the smell of the lake . Summoning the Mon Calamari Padawan Bant Eerin to the lake , Jinn tasked her with searching the bottom of the massive pool for clues . Upon surfacing , Eerin brought with her a chest , similar to the ones used on her homeworld Dac . Opening the air - tight compartment , Eerin revealed the items that had been stolen from the Temple , including the lightsaber of former Padawan Obi - Wan Kenobi . Jinn and Tahl returned to the lake soon after to set a trap for the mysterious thief that was vandalizing the Temple . Due to the heightened security , the lights in the Lake Level were powered off , allowing the two Masters to travel unseen throughout the chamber . Hoping to catch the thief upon his return , Jinn was about to capture a suspect when Tahl ' s Council - appointed navigation droid , TooJay , appeared and alerted the intruder , causing them to flee . While the trap was foiled , Jinn managed to get a glimpse of the thief and recognize him as Padawan Bruck Chun . Upon his return to the Temple , former Padawan Kenobi walked with Eerin around the lake trying to think of a way to impress upon the Council his commitment to the Order and his sincerity behind the request to accept him back . As they walked the pair noticed that a horizontal turbolift car was dangling precariously from a broken shaft . Acting quickly , Kenobi accessed the service stairway that would take him up into the room ' s illumination bank . Climbing gently into the shattered shaft , Kenobi assisted Master Ali - Alann in the removal of the youngling clan he was escorting to the nearest dining hall . Meanwhile , Eerin had rushed to the High Council Tower , having found the turbolift control faulty , to notify the Council . The august body had rushed to the lake and used the Force to hold the car steady while the younglings were escorted to safety . Upon their return to ground level , the Council thanked Eerin for her quick thinking while they reprimanded Kenobi for acting alone . The Council deemed the Lake Level unsafe and closed it until repairs could be made . Soon after Jinn and Tahl discovered that Dark Jedi Xanatos was behind the attacks , Eerin came to Jinn and told him about the tunnels running under the lake . Jinn , Kenobi , and Eerin entered the lake and dove deep into the water , accessing a hidden grate located in a boulder . Passing through the tunnel they were deposited into the main water service tunnel that provided water to the fountains and reflecting pools in that wing of the Temple . After searching the tunnels , Jinn confronted Xanatos over the water purification units ; after a brief duel Xanatos slipped away and Jinn and the Padawans retreated back to the lake . Several decades later , at the end of the violent Clone Wars , the Republic which the Jedi had served for so long was dissolved and transformed into the Galactic Empire . The Temple was placed under martial law by decree of Order 66 . The 501st Legion of the Grand Army of the Republic , led by Darth Vader , stormed the Temple and executed its occupants , damaging the Temple in the process . The Temple ' s Lake Level was laid to waste , the water turned off , leaving the plants to die and the water to grow clouded and tepid . The Lake Level would stand in silence for several more decades , slowly crumbling from disuse and lack of care . When Sith Lords Darth Sidious and Vader were slain , the Empire lost balance and was eventually driven from Coruscant by the New Republic . During the Yuuzhan Vong War Coruscant was devastated by terraforming , causing the Temple to crumble and reveal parts of the foundation . When the Galactic Alliance reclaimed the world , Chief of State Cal Omas , ordered the Reconstruction Authority to rebuild the ancient edifice as a gift for the great sacrifices made by the reformed Order against the Yuuzhan Vong . While the structure was rebuilt using blueprints of the old building , it is unknown if the Lake Level was reconstructed or replaced . Layout . Located within the Jedi Temple , the Lake Level made up five stories of the massive structure . Upon entering it was said the atmosphere of the chamber made one feel as if they were standing on the surface of the planet . The floor was covered with grass and flowering plants . Trees were strategically placed near benches or rocks . At the center of the chamber was an expansive lake , the clear green water of which lapped the beach area with its gentle rippling . In between classes , it wasn ' t unusual for the younger apprentices to come to the lake for a relaxing swim in the calm waters . Lined with the stones and sand , the bottom of the lake concealed portals into the Temple ' s massive water tunnels which led away into the giant purification complex . To continue the illusion of being outdoors , the ceiling of the Lake Level was covered in carefully placed light - banks that created the illusion of the outside sky . Beyond the illusion were catwalks and service stairways used to accommodate the Temple employee s that maintained the light systems . Additionally , a horizontal turbolift ran above the lake connecting the dormitories with a dining hall .
