Alderaan Enclave The Alderaan Enclave was a compound that lay deep beneath the surface of the volcanic planet Sullust . The Enclave was built by a group of Alderaanian s after they emigrated from their homeworld of Alderaan and bought the land from the native Sullustan s . The Alderaanians had originally come to provide culture and education to the native population , but the enclave became a sanitarium after Alderaan was destroyed by the Galactic Empire to test their Death Star ' s capabilities . Preserver Jora Astane was the leader of the Alderaanians on Sullust after Alderaan was destroyed . Prince ss Leia Organa , as an ambassador for the Rebel Alliance , came to the compound not long after Alderaan ' s destruction to gather and protect the survivors of the Disaster . However , an unknowing spy in Organa ' s company , in the form of the Alderaanian girl Tace , leaked their position to the Empire , who sent an Imperial strike team to kill the Alderaanians ; but they were beaten by Organa ' s team and a herd of rockrender s who caused significant damage to the compound . Preserver Astane and her people subsequently joined Organa on her quest and evacuated the compound with the help of the Sullustan smuggler Nien Nunb . Description . The Alderaan Enclave was a series of cave systems located deep underneath the surface of the volcanic planet Sullust , and south of the Mayjein Eruption . The compound consisted of several large chambers , one of which was very large and housed several structures built in an Alderaanian architectural style around a series of magma pools . A command center was located near the roof of the cave in an alcove overlooking the buildings where the leader of the Alderaanian cloister , Preserver Jora Astane — whose responsibility it was to preserve what was left of Alderaan ' s culture — and other technician s , including Bornae and Astane ' s assistant Covis , monitored the traffic of people in - and - out of the compound . There was more than one entrance into the Enclave ; one entrance , auxiliary hatch three , was sealed from the inside , and had a long tunnel leading from outside the compound into an antechamber . The Alderaanians were obsessed with security because of the Empire ' s ruthlessness and , as such , there was more than one surveillance room that contained holoprojector s , datascreen s , and weapons caches . But the biggest of them all was the Eyewell ; the Eyewell spiraled downward farther underground , and was located just beneath the Preserver ' s command center . It housed several dozen computer stations that were manned and monitored by Alderaanians who used the security equipment to oversee the Enclave , the surface of Sullust , and even Sullust ' s moon . The entire complex was built over a mine called Mine 3601 . A natural water way carved its way through the mine , along with a river of magma . After the Enclave was finished and the Alderaanians moved in , the mine and waterway became polluted with debris and waste from the complex . A herd of rockrender s , large orange - colored cave - dwelling beasts , lived in the mine , surviving off of mineral deposits located in the caves . History . The Alderaan Enclave was built in a large cave system south of the Mejien Eruption by a group of Alderaanians sometime during the reign of the Galactic Empire . The Alderaanians that constructed the Enclave pooled their wealth to buy the land from the native Sullustan s in the hopes of remaining hidden from the Imperials who had a presence on the planet mining minerals and manufacturing Imperial weapons and war machines in the SoruSuub Centroplex weapons factory . The inhabitants of the enclave constructed many buildings and expanded on several caves to increase the enclave in size . They had emigrated to Sullust in the hopes of providing cultural services , arts , education , and food to the local population . During the Galactic Civil War , the Alderaanian homeworld of Alderaan was destroyed by the Empire to test their ultimate weapon , the Death Star . Alderaan ' s Prince ss , Leia Organa , had been forced to watch her homeworld be destroyed . Therefore , she undertook a mission to rescue the survivors of Alderaan throughout the galaxy ; albeit , against direct orders from her superiors in the Alliance to Restore the Republic . The inhabitants of the compound became paranoid after the destruction of their homeworld , as the Empire was hunting down Alderaanians . Therefore , they stepped up security and cut off communications outside the compound . A native Sullustan smuggler named Tivvy even claimed that the Alderaanians had gone insane in their plight to remain hidden . Organa , her pilot Evaan Verlaine , and her astromech droid R2 - D2 , arrived on Sullust and landed on the surface near the enclave in a T - 1 shuttle . They engaged Tivvy who led them into the compound through the enclave ' s auxiliary hatch three . Their arrival was noticed by Preserver Jora Astane who recognized the Princess ; however , she considered Organa a traitor for suspiciously surviving the destruction of Alderaan , so the Preserver ordered a rifle squad to apprehend the Princess . Organa and her team soon overpowered the squad and were escorted to the Preserver deeper into the compound . The two parties came to a distrustful agreement and Astane took them on a tour of the enclave , eventually making their way to the Eyewell . Word came while they were in the Eyewell that an Imperial cruiser was nearby and had dispatched a " Sentinel " - class landing craft to storm the compound , the signal of which had been intercepted by Covis as having originated from the T - 1 shuttle — in reality , the message was between two sisters : Tace and Tula . Tace had been keeping in contact with her sister in order for their pair to meet up , but Tula , however , had other plans — she had become an Imperial officer and inclined to capture Organa on the behest of Commander Dreed , her superior officer on the Star Destroyer she was stationed . Astane ordered her subordinates to kill Organa and her team , but she and Verlaine fled into the Eyewell ; prompting the Preserver to order her squads to hold their fire in fear of damaging the equipment and computers . Organa utilized one computer to send a message to the " Lord Junn " , a starship that was holding the Melodic Order , a group of Alderaanian musician s Organa had recently rescued from Naboo , was in orbit over Sullust . Then , the Imperial landing craft touched - down and its stormtrooper platoon began drilling through the ground into the enclave . Organa , Artoo , and Verlaine fled through the bottom of the Eyewell to Mine 3601 . They were distraught with the pollution and mess the Alderaanians had made . The Preserver expected the Imperial troops to invade through auxiliary hatch three and stationed her troops there . Instead , the stormtroopers forged a hole in the ceiling above where the troops were stationed and repelled through into the chamber while firing on the Alderaanians . Meanwhile , Artoo piloted a repulsorcraft and shot off down a cavern and began herding several rockrenders through the cavern wall and into the chamber where the fighting was . The imposing rockrenders had no trouble plowing through the wall and eating the stormtroopers whose armor possessed minerals they consumed . Soon , the Imperials were all dead , the rockrenders left , and Astane pledged herself to Princess Leia . Immediately after , the Alderaanians , with the help of another Sullustan smuggler named Nien Nunb , fled Sullust . Behind the scenes .
