Lehon Lehon , also referred to as Rakata , Rakata Prime , and the Unknown World , was the homeworld of the Rakata species and the secret capital of their Infinite Empire . Description . Lehon was a tropical world that inhabited a remote and relatively unknown corner of the galaxy known as the Tempered Wastes , a largely void area of space . Its surface was largely covered by oceans which were dotted by numerous clusters of islands and archipelagos . It was the only habitable planet in the Lehon system , but it shared an orbit around its primary star with the Star Forge , an ancient Rakatan space station and factory which drew its fuel directly from the system ' s primary star . The planet itself was orbited by two small moons , but one of them was close enough to be visible from the surface during daylight , covering a significant portion of the sky . History . Infinite Empire . Millennia before the birth of the Galactic Republic , the planet was the capital of the ancient Infinite Empire of the Rakata ( c . 35 , 000 – 25 , 200 BBY ) . The Rakata were a scientifically advanced species that powered their technology with natural Force sensitivity and used their knowledge to enslave and subjugate other , less - developed species . They were responsible for creating several technological marvels including the semi - sentient Star Forge , which churned out war droids and starships at an alarming rate . The Rakata built large cities on their homeworld , which later became crumbling ruins reclaimed by the jungle . The Infinite Empire , which , at its peak , included approximately 500 planets , Eleven billion Rakata , and over a trillion slaves , ended in a brutal civil war . During the final days of the Empire , the Rakata were forced to flee back to their homeworld due to widespread slave insurrections and the ravages of a deadly plague which stripped them of their Force abilities , but , on its surface , their war continued . The surviving Rakata , now extinct beyond their homeworld , succumbed to barbarism , with cannibalism becoming common among their warring factions . Battling warlords severely damaged the surface of Rakata Prime through the use of weapons of mass destruction that fragmented it into islands . The majority of the species were forced to flee underground because their planet had become almost uninhabitable . Jedi Civil War . During the reign of the Galactic Republic , various Rakatan tribes , including the tribe of the One , emerged back on to the surface of the now backwater planet , but their civilization was still one of battle and bloodshed . Only the Elders — descendants of the priest caste of the Infinite Empire — kept memories of their once glorious past alive . Only they had access to the advanced technologies their species had created long ago . They used it to isolate and guard their forbidden lore in the Temple of the Ancients . The planet itself was protected by a disruptor field that could disable any incoming ship ' s communications and navigational systems . This field , operated from the summit of the Temple , was originally constructed to protect the Star Forge . Over the millennia , the planet had become a technological graveyard , with its tropical islands strewn with the wreckage of spaceships unfortunate enough to have stumbled across the mysterious planet ' s hidden location . The planet was infested with foreign fauna , including rancors and gizka , which the Rakata said came from the sky aboard crashed ships . Lehon was visited by Revan twice , in 3959 BBY and 3956 BBY , during the Jedi Civil War . Both times , he used the help of the Elder Rakatan tribe to enter the Temple of the Ancients and was granted passage to the Star Forge itself . However , the first time , as Dark Lord of the Sith , he lied to the Rakata , saying that he would destroy the great factory , while in fact he wanted to claim it for himself and use it to build an immense Sith fleet to challenge the Republic . The second time , after his redemption , Revan was given the task of freeing an elder from the Black Rakata . After entering the One ' s chambers , Revan killed the One and other Black Rakata . With this , the elders allowed Revan to enter the temple . Revan disabled the disruptor field to allow the Republic fleet and his own ship , the " Ebon Hawk " , to breach the factory ' s defenses . When the Star Forge was eventually destroyed in a fierce battle between the Republic and the Sith , the Republic commanders — Admiral Forn Dodonna and Jedi Master Vandar Tokare — celebrated the end of the Jedi Civil War at the Temple exterior . During the ceremony , Revan and his companions were each awarded with the Cross of Glory . Post - Civil War . After the Jedi Civil War , the entire Lehon system was littered with wreckage from the destroyed Star Forge and the remnants of crippled vessels which had fought in the final battle of the war . Lehon itself became surrounded with asteroid - like rings of rubble which made navigation to and from the planet extremely dangerous . Though the wreckage would have been valuable as a source of resources , the Galactic Republic chose to make the entire system a protected historical site which was not to be entered without permission . Eventually , the planet became accessible to the rest of the galaxy . Lehon was incorporated into the Galactic Republic as a historical preserve . However its true nature was kept secret to avoid creating a panic or encouraging opportunists to attempt to make use of Rakatan secrets . Tourism was kept at a very minimal level . While some Rakata took to the stars , a majority of the population refused to move off - world . In 3638 BBY , during the Galactic War , Revan returned to the planet with a large group of fanatical followers with the hopes of building an army to fight the Sith . He established his main base of operations at the Temple of the Ancients , which was later attacked by a mixed squadron of both Republic and Sith loyalists . Revan ' s lieutenants were defeated , thwarting the former Dark Lord ' s plans . Around 1000 BBY , Darth Bane arrived on Lehon to access Darth Revan ' s Sith Holocron . Upon landing on the surface , he sensed that the planet was still deeply steeped in the dark side of the Force , even more so than Korriban . By the time of his arrival , the planet was reasonably well - known , but it was largely ignored because many of the darker aspects of Rakatan history had been suppressed by the Republic and the Jedi . In a battle with the Sith Lord Kas ' im , Bane destroyed a part of the Temple of the Ancients by collapsing one of the major archways , in a duel with his former master . Behind the scenes . In " " , the planet was referred to as the " Unknown World " . " The New Essential Chronology " was the first source to give an official name as " Rakata Prime " , until its native name was eventually given as Lehon in " " . In a non - canonical ending of " Knights of the Old Republic " , if Revan goes to the dark side at the top of the Temple when he reaches the shore announcing his turn , Carth Onasi runs off into the forest while Mission Vao is killed either by Revan ( in which event Zaalbar is also killed ) , or Mission is killed by Zaalbar under the forceful persuasion of Revan . At this point , Carth is not heard from again until " " .
