Ash Worlds The Ash Worlds , a region that was originally known as the Kiirium Reaches , was a sector located within the Outer Rim Territories , between Hutt Space and the Tion Cluster . History . Settlement . The Kiirium Reaches were settled by Humans in ages before the rise of Xer VIII in the Tion Cluster . Xim the Despot quickly expanded his empire into these worlds between 25 , 120 and 25 , 096 BBY . The region was dubbed the Kiirium Reaches , and the lush planets Huronom and Astigone became the Seventh and Eighth Thrones of the empire . Destruction . After the defeat of Xim , the Hutts made the Kiirium Reaches a buffer between the Hutt Empire and the Tion Cluster , regularly raiding it for slaves . After the Tionese made contact with the Galactic Republic in 24 , 500 BBY , however , the Hutts saw this as the prelude to an alliance against them . Taking pre - emptive action , the Hutts exterminated the Tionese to the last man , woman , and child within the old borders of the Kiirium Reaches in a genocidal campaign known as the Devouring . Their settlements were vaporized , their worlds bombarded and poisoned , their histories , and eventually even their names erased . The planet ' s name were lost and most were renamed . Xim ' s hyperspace beacon s were destroyed or towed away for the Hutts ' own purposes , leaving future explorers to find new routes through the desolation . Only the beacons and a few Tionese worlds along the Salin Corridor ( known at this time as Warriors ' Trace ) were spared to preserve a potential Hutt invasion corridor to the Tion and make sure there were hostages to take along the way . The location of the historical Kiirium Reaches was lost and was the subject of much debate among scholars for millennia . The locations of Huronom and Astigone were forgotten , and they became known as the Lost Thrones of Xim . Columex and Trogan were popular suggestions for the location of Huronom , and numerous luxury resorts on Centares bore the name Astigone to claim the title of the Eighth Throne . Farther afield , the likes of Jabiim , Lucazec and even Lantillies were proposed as Lost Thrones . This region of thousands of barren worlds still bearing the invisible scars of radiation was finally called the Ash Worlds , a name so widely known that the Republic adopted it for that sector of space . The spared Kiirium star systems along the Salin Corridor were not included in the Ash Worlds . Astronomer s had scoured the area searching for the remnants of a supernova or some other devastating natural event , but nothing had ever been found . The Devouring was remembered in a garbled fashion on many worlds of the Tion Cluster as a winter holiday . For some worlds such as Stalimur , the holiday was a time for pious reflection , and the day even took the name " the Devouring " . On other worlds it was a more light - hearted festival , such as the Wakemeet of Barseg . Rediscovery . After 19 BBY , the Galactic Empire interdicted many of the Ash Worlds for weapons research . However , this did not discourage the historian Bleys Harand , who made numerous secret expeditions into the Ash Worlds . Harand and his students , including his protégé Henrietya Antilles , explored the Ash Worlds and reported that the radiation levels on numerous planets fit the profile of fission bomb attacks some twenty - five thousand years earlier . With the Hutt Empire known to have conducted similar actions , Harand argued that the Ash Worlds were a remnant of the Kiirium Reaches , and that the Devouring holiday was a memory of a genocidal campaign waged by the Hutts against the Tionese . Further explorations into the Tion Cluster led to Henrietya Antilles ' discovery of the Great Duinarbulon Mausoleum , which contained a large number of ancient records . After deciphering one of them , the Antilles Map , Harand was proved correct : the Map showed that the hostile world of Wyndigal 2 was once Huronom , while the anonymous OHS3842 - 03 had been Astigone . Harand ' s theory about the Kiirium Reaches was quickly accepted by Ximologists and by 30 ABY was considered the academic consensus .
