Malachor V Malachor V , or simply Malachor , was an Outer Rim planet located in the Malachor system . Prior to the final battle of the Mandalorian Wars , the planet was fertile and hospitable . After the cataclysm caused by the Mass Shadow Generator , it became a cracked and twisted wasteland covered with jagged cliffs and plagued by constant lightning storms . It was inhabited by monstrous storm beast s . The gravity of the planet was unstable , which made it dangerous for starships to stay there for very long . History . Early history . The early history of Malachor V remained largely unknown . Vague reports established that an ancient branch of the Sith — the True Sith — constructed a Sith academy on the planet ' s surface . In time the Academy , and Malachor itself , became a place of great power within the dark side of the Force . At some point in time the empire of the True Sith disintegrated , and they retreated further back into the Unknown Regions , seemingly abandoning and forgetting their stronghold on Malachor V . It had been suggested by some that the Sith who populated the planet were members ( or former members ) of the Sith Empire . The hypothesis remained controversial among historians and had yet to be proven , however . The historical records clearly pointed out , though , that there was some connection between the mysterious True Sith and the Sith Empire . The extent and manner of that connection also had yet to be discovered . As it turned out , the True Sith was a remnant of the Sith Empire , led by the man who would become the Sith Emperor . Fleeing their defeat at the end of the Great Hyperspace War , they eventually came to the world of Dromund Kaas . At some point , they apparently came to Malachor V where they built the Trayus Academy . During their time on Malachor V , the Empire experienced an uprising led by Dakar Sol . Mandalorian Wars . Centuries later , Malachor became the site of the final battle of the Mandalorian Wars , during which the most terrible atrocity of the war was committed . Malachor was restricted to Mandalorians , a taboo in Mandalorian culture , something that the Jedi General Revan used against them in order to win the war . Revan amassed an enormous fleet composed , not coincidentally , of Jedi and Republic soldiers whose loyalty to Revan was in question , at the planet , providing the Mandalorians with a target that was too good to pass up . At the head of this force Revan placed one of their top generals : Meetra Surik , who was later known as the " Jedi Exile " . During the Battle of Malachor V , Revan single - handedly slew Mandalore the Ultimate aboard the warlord ' s flagship . As Republic and Mandalorian forces outsystem from the planet itself continued to clash , Surik ordered the activation of the Mass Shadow Generator superweapon with a single , wordless nod towards its inventor , Bao - Dur , in order to prevent the Mandalorian forces they faced from overwhelming them and moving on to attack Revan ' s forces from behind . In an instant , Malachor ' s gravity crushed every combatant in and around its atmosphere — Mandalorian , Republic , and Jedi alike . Malachor ' s surface was transformed into a barren , shattered and lifeless wasteland — all of Revan ' s enemies were eliminated in a single stroke . The planet was left scarred from the battle as the surface had been obliterated . Long afterward , there was still evidence of crashed Republic cruisers buried deep within the surface . Jedi Civil War . Following their victory , Revan journeyed into the Unknown Regions with Malak in search of Mandalore ' s mysterious masters , which the pair learned to be Sith on the ice world of Rekkiad . However , they were ultimately turned to the dark side by the Sith Emperor , who sent them back to the Republic to wage war . But the Emperor underestimated the pair ' s resolve , as they broke free of his commands not long after and decided to conquer the Republic for themselves and adopted the title of Dark Lord of the Sith . During the Jedi Civil War , circa 3959 – 3956 BBY , he used the Trayus Academy , located on the planet ' s surface as one of several secret Sith bases dedicated to the conversion of captured Jedi Knights . Throughout the war , Jedi were captured by his Sith Assassins and other specially trained forces , and brought to the Academy . The corruptive nature of the location weakened their wills so that Revan and their loyal servants could easily lure them to the dark side . In such places , he converted hosts of Jedi into fanatical Dark Jedi and Sith Assassins for his Sith Empire . Several years after the war had ended , Revan ' s old Master Kreia traveled to Malachor V in search of what had corrupted her apprentice . Like Revan , she was corrupted by the dark side energy resonating throughout the planet ; in secret , she then took the moniker of Darth Traya and began training new students of the dark side at the Trayus Academy , which had remained unscathed despite the devastation wrought by the Mass Shadow Generator . Among her first two students were Darth Sion and Darth Nihilus , who soon became powerful enough to overthrow her . The three Sith Lords formed an uneasy alliance against the Jedi , but the two apprentices eventually broke the alliance , and Darth Traya was cast down , stripped of her power , and exiled from Malachor . Final destruction . In 3951 BBY , Kreia located Meetra Surik , the only Jedi who had fought at Malachor V and not been killed or corrupted . Plotting revenge against her apprentices , Kreia began orchestrating events to set up a final confrontation between herself and Surik at the Trayus Academy . After slaying Darth Nihilus , Surik arrived at the Academy and defeated the Sith there , including Darth Sion and Darth Traya , thus silencing the echoes of the atrocity that , until then , Malachor had still sent through the force . While Surik fought in the Academy , Bao - Dur , the technician who had originally designed the Mass Shadow Generator , ordered his remote to reactivate the superweapon in an effort to destroy the tainted world of Malachor V once and for all . Despite G0 - T0 ' s attempts to thwart it , the remote succeeded in its task . As Surik departed Malachor in the " Ebon Hawk " , the dead planet crumbled under the pressure of the mass shadow ' s gravity , leaving behind only asteroids and the wreckage of many hundreds of blasted warships , a grim memorial to the Battle of Malachor V . Legacy . By 3640 BBY , surveys showed small pockets of biological life was still active in Malachor V ' s remains . The planet ' s infamy led to its name becoming a curse word , synonymous with " Hell " . By the Clone Wars , Republic Colonel Meebur Gascon used it in anger . The planet , alongside its infamous use of the mass shadow generator and its destruction , was later used as an example of ancient superweapons by Bevel Lemelisk of the Imperial Department of Military Research in the " " , the official field manual for the Imperial Military . Upon finding this reference to the weapon and Malachor V , Luke Skywalker pondered whether he should investigate the planet for possible artifacts belonging to either the Jedi or the Sith . Behind the scenes . If the player chooses to take the path of the dark side , Surik throws Darth Traya ' s body into the abyss and takes the title of Dark Lord of the Sith ; the planet itself survives . In the Dark side ending Malachor V appears more stable .
