Tion Cluster / Legends The Tion Cluster was a star cluster located within the Outer Rim region of the galaxy . An unremarkable part of the galaxy by the time of the Galactic Civil War , it was most famous for historically being the home of the short - lived empires of Xer VIII and his son Xim the Despot . Geography . The Cluster was at the edge of one of the galaxy ' s spiral arms . Just Coreward of the Cluster was the Cron Drift and the former Jedi stronghold of Ossus . The Perlemian Trade Route passed close to the cluster at Lianna , and beyond the Tion became known as the Far Perlemian . Its western border was defined by the line of Kanaver , Jhantoria , Lianna , and Foran Tutha , while its southern rim was defined by a line from Foran Tutha through Saheelindeel to Dellalt . Its eastern fringe was defined by a line from Dellalt to Raxus Prime , and its northern border by a line from Raxus to Kanaver . The Indrexu Spiral was a prominent nebula running from the Indrexu sector in the north south through the Cluster . In the Imperial Period , the Galactic Empire carved the Cluster into three sectors : the Tion Hegemony , the Cronese Mandate , and the Allied Tion . Surrounding sectors with Tionese influence included the Indrexu sector , the Keldrath sector , and the Thanium Worlds , and were known as the " Greater Tion " . The Tion Hegemony was divided into two quite different regions : the cluster of ancient , averagely - wealthy systems at the head of the Desevran Trace linking it to the Perlemian , known as the Livien Worlds for their connection to the Xim - era Livien League , and the string of systems beyond the Indrexu Spiral along the Tion Trade Route known as the Back Spiral , which were mostly poor and had little to do economically or culturally with the Livien Worlds . The Livien Worlds even lacked a hyperlane connecting them to the Back Spiral in their sector . The Allied Tion had little historical identity , having been separated from the Tion Hegemony after the Clone Wars by the Empire . Traditionally , this area was a buffer between the Tion Hegemony and Cron , but by the time of the Galactic Alliance the Allied Tion was known for its manufacturing and trade : the Cadinth Run from the Perlemian saw a great deal of traffic , though little of that passed beyond the sector capital of Jaminere to the Indrexu Route and the Desevran Trace . The Cronese Mandate was by far the largest of the Tion sectors , and having been the seat of Xer ' s Kingdom of Cron , was typically more outward - looking than the rest of the Cluster and typically looked on their neighbors as unsophisticated . Its principal worlds were along the Greater and Lesser Cronese Arc s ; the Kismaano Bypass and the Indrexu Route connected it to the Allied Tion , while some traders followed the Arc to Saheelindeel and the worlds of the Tion Hegemony ' s Back Spiral . The Cluster contained about 12 , 000 stars , orbited by almost 600 habitable planets . Of these 600 , 464 were part of the Cronese Mandate . The other 136 were divided between the Tion Hegemony and the Allied Tion sector . History . The Tion Cluster had inhabited Human settlements pre - dating both the Old Republic as well as several planets in the Core Worlds . The Humans were descended from a lost sleeper ship from Coruscant . They developed a mixed society with Rakata castoffs , and utilized some of their technology to create beam tube s circa 27 , 000 BBY , and eventually limited hyperdrives that relied upon fixed - position hyperspace beacon s . Rakata Force - sensitive technology was also present in Xim ' s war - robot s . The limited technology prevented the Tionese from having contact with the Core , eventually forgetting their origins and remaining isolated from the rest of the galaxy . The Tion Cluster achieved galactic prominence in the century before the foundation of the Galactic Republic , when the pirate - king Xer VIII unified much of the cluster in the Cronese Sweeps , carving out the Kingdom of Cron ruled from Argai . His son , Xim the Despot , completed the conquest with the capture of the Livien League , then began a prolonged Expansionist Period that expanded his empire to the edge of the Radama Void . The Tionese , however , soon fell upon Hutt Space , resulting in a disastrous war that saw the death of Xim and shattered the region . After Xim ' s death , much of the Cluster fell into infighting between various successor states , including the Kingdom of Cron , the Jaminere Marches , the Keldrath Alignment , the Indrexu Confederation , and the Thanium Worlds . The Tion Cluster united for one last time to form the Honorable Union of Desevro & Tion in 24 , 000 BBY to wage war against the expanding Galactic Republic , but after a century of fighting , the Cluster surrendered and joined the Galactic Republic in 23 , 900 BBY . Thereafter the Tion Cluster became an unremarkable collection of sectors in the Republic , its Xim - era colonies in the Kiirium Reaches devastated by the Hutts in an effort to create a buffer zone between them and the Republic . In the Republic ' s final years , the Cluster ' s disparate states eventually joined up to form two dominions : the Tion Hegemony and the Kingdom of Cron . Both joined the Confederacy of Independent Systems during the Clone Wars . Count Dooku used a communications center on Raxus Prime to broadcast Separatist propaganda prior to the conflict . During the Wars , Dooku built up a secret base on the world and hunted the Force Harvester superweapon on the planet . The Separatist Parliament , meanwhile , performed its duties on Raxus Secundus , a heavily fortified world in the same system . In retaliation for the Cluster ' s Separatist allegiance , the Galactic Empire divided the area into new sectors after the war , renaming the Kingdom of Cron the Cronese Mandate and carving the Allied Tion , the Indrexu and the Keldrath sector s out of a shrunken Tion Hegemony . The Tion Hegemony was allowed a nominal independence , which was seen as humiliating . Due to the strategic location of the Cluster ' s sectors , the Imperial Military increased its presence inside the cluster and attempted to use the nearby Calamari sector as a forward base to rapidly launch strikes at the Cluster from outside . During the Galactic Civil War , several star systems inside the Tion Cluster became battlegrounds between the Empire and the Alliance to Restore the Republic , during Operation Strike Fear . Later , some of the Heroes of Yavin encountered the notorious bounty hunter Boba Fett on Panna Prime , as part of a trap devised by Darth Vader to track down the Rebel leadership . After the Battle of Endor , the entire Cluster was integrated in Zsinj ' s Empire . The three sectors stayed under Zsinj control until his death in 8 ABY , becoming independent again . The New Republic showed little interest in the region , and talks for re - unification were held in the years after Endor . The Yuuzhan Vong raided the Cluster ' s border worlds during their invasion of the galaxy , but did substantial damage only to the planet Caluula .
