Dxun Dxun ( ) , also known as the Demon Moon , was the largest of four moons that orbited the Inner Rim world of Onderon . Like its parent planet , it was covered almost entirely by dense jungles that were populated by many species of fierce , predatory animals . Description . Despite being temperate and habitable , the jungles of Dxun posed major challenges for its inhabitants . Due to its constant rains and wet climate , mechanical devices did not last long and required continuous maintenance . Moreover , the jungles were inhabited by many dangerous predators such as boma s , cannok s , drexl s , maalraas , skreev s , and zakkegs , forcing the moon ' s inhabitants to be armed at all times . Though considered a moon of Onderon , Dxun and Onderon were almost sister planets . They were so close to one another that it was only a short shuttle ride between them , and they even shared a bit of the same atmosphere . Every year , during Dxun ' s summer season , the atmospheres of Onderon and Dxun would connect . This allowed the vicious Drexls to wander and settle on Onderon , thus laying the foundations for the Beast Wars . History . Early history . At the end of the Beast Wars , Jedi Master Arca Jeth decided to relocate the sarcophagus of Freedon Nadd , the former Dark Lord of the Sith and king of Onderon , from Onderon to Dxun , in an attempt to prevent future Sith from drawing on its power . The plan worked for the most part , though two of history ' s most pivotal Sith Lords , Exar Kun and Darth Bane , would later manage to enter the tomb of Freedon Nadd on Dxun . At the end of the Great Sith War in 3996 BBY , Mandalore the Indomitable , leader of the Mandalorians , was eaten alive by the vicious beasts of Dxun . Mandalorian Wars . After assuming the leadership of the Mandalorians , Mandalore the Ultimate made Dxun his stronghold , from which he planned his attack on the Galactic Republic . In 3963 BBY , the Mandalorian Wars expanded into a galaxy - wide conflict when the Mandalorian Neo - Crusaders began their invasion of the Republic . From their headquarters on Dxun , Mandalore ' s forces attacked and took nearby Onderon in mere hours . A battle with the Republic forces took place on the moon , but it was little more that a rear - guard holding action by the Republic . Years later , after the Jedi Revan and Malak had entered the war and pushed the Mandalorian forces back to their original Dxun staging - grounds , a far more bloody battle was fought . The Republic attempted to capture the Mandalorian headquarters on Dxun . Republic forces managed to defeat the Mandalorians , but the victory came at a heavy cost . The Mandalorian outposts were entrenched and well defended by hidden mines , traps , anti - air turrets , and the ferocious inhabitants of the jungle itself . During the bloody battle , the Republic lost ten soldiers for every Mandalorian killed . The Jedi Exile , who was in command of the battle , was forced to sacrifice dozens of her soldiers , sending them on a suicidal charge to disable the minefield that was the last obstacle keeping them away from the Mandalorian fortress . After the battle , the Republic military did not bother to demolish many structures that the Mandalorians had built ; nor did they uncover the many hidden weapons caches providently left in case the Mandalorians were someday to return . Onderon Civil War . In 3956 BBY , Canderous Ordo took the title of Mandalore and gathered a handful of Mandalorians , most of whom were mercenaries at the time , on the Dxun moon , in the rebuilt headquarters of the old Mandalore . There they regrouped , concealing their presence from both the Republic and the native Onderonians , silencing all scouts who came anywhere near their encampment . Canderous hoped that , one day , the Mandalorians of Dxun would regain their former glory . The Jedi Exile landed in the jungles of Dxun when her ship , the " Ebon Hawk " , was severely damaged in a space battle over Onderon where Republic forces commanded by Colonel Tobin attacked them unprovoked , almost definitely under General Vaklu ' s orders . While exploring the jungle , the Exile was attacked by three of the Zhug brothers , who were also stranded by the space battle and looking to collect on her bounty . Later , the Exile was discovered by a group of Mandalorians , who brought her to the new Mandalore . She needed to get to Onderon to search for Jedi Master Kavar , but Canderous told her that she would need to prove herself first . The Exile performed several tasks for the Mandalorians and proved herself honorable , and Canderous made good on his word , providing a shuttle and accompanying her to the city of Iziz . When the Onderon Civil War erupted , the Mandalorians fought alongside the Jedi Exile , despite , or perhaps " because " of her involvement in their defeat at Malachor V . Canderous provided the Exile with a repaired Basilisk war droid ( several of its minor systems were malfunctioning ) so that she could get into Iziz . Meanwhile , the Mandalorians and a party of the Exile ' s companions headed into the jungle to fight General Vaklu ' s Sith allies , who landed on Dxun via a craft of a KT - 400 military droid carrier ' s design . They found the Sith inside and outside the Tomb of Freedon Nadd , where they were conducting a ritual to keep Onderon beasts under the control of Sith beastmasters . The party started at a tunnel where they had to get through a minefield and disable a motion sensing alarm for alerting the Sith of a hostile presence . After , doing that , they disabled a power generator that controlled the droid sentry force of the Tomb and continued to neutralize three Sith trooper s and a Sith officer who were guarding a terminal , what looked like a storage shed and the Sith ' s transport near the Tomb entrance . They then initiated a program via the terminal to order the mechanical sentry force ( droids and turrets ) to attack all hostiles and friendlies in the area , reducing the amount of the Sith the Exile ' s party ' s needed to take care of . The party continued to charge the Tomb entrance , which was heavily guarded by Dark Jedi Apprentices , Sith troopers and Sith Commandos — all of which were taken out and allowed the Exile ' s party to proceed into the Tomb itself . After battling Sith Commandos , Sith troopers , Sith officer s , Sith Lords , Sith War Droid , Boma beasts , and Dark Jedi Apprentices to clear the tomb of all enemies , the party opened a locked door via an ancient terminal and met two Dark Jedi Masters and a Sith Master performing a ritual , which would put the Bomas under control of the Sith force attacking Onderon . They managed to accomplish their task before the Exile ' s party reached them . Following the confrontation , the Sith Master attempted to corrupt the party ' s leader to the dark side of the Force but was unsuccessful . The three Sith then went on the offensive ; however , they were bested , resulting in their death . The party leader then removed Freedon Nadd ' s lightsaber from his sarcophagus and met up with Xarga who brought the Exile ' s party back to the " Ebon Hawk " and told them of the Exile ' s successful mission to bring peace to Onderon . New Sith Wars . Millennia later , in 1000 BBY , the Sith Lord Darth Bane , after the Seventh Battle of Ruusan , crash - landed on Dxun . He immediately recognized it as a world infused with the dark side . It was here , in the well of darkness near Freedon Nadd ' s tomb , that Bane acquired orbalisk armor . By the time of Darth Bane , while the tomb and the well ranked as significant Dark Side sites , the entire moon had become a dark side site . Between the eras of Exar Kun and Darth Bane , Dxun was a common pilgrimage for those attempting to master the Dark Side of the Force . Behind the scenes . The image of Dxun in the " " Dxun / Onderon turret minigame bears a resemblance to a mosaic of images taken by Viking 1 Orbiter in February 22 , 1980 .
