Nathema system The Nathema system was a star system that was located in the Outer Rim Territories ' s Chorlian sector . Containing the vibrant agriworld Nathema , originally named Medriaas , the system supplied the Sith Empire with foodstuffs before the Empire ' s destruction in the Great Hyperspace War with the Galactic Republic in 5000 BBY . Nathema ' s ruler , the Sith Lord Vitiate , subsequently annihilated all life on Nathema with a dark side ritual , leaving the star system barren and lifeless . As Emperor of a reconstitued Sith Empire , Vitiate erased all navigational data on the Nathema system in order to hide the evidence of his crimes , and the system received only a few scattered visitors throughout the following millennia as a result . Description . The Nathema system was a star system located within the Chorlian sector in Outer Rim Territories , on the far eastern edges of the Sith Empire — a region that fell within the Unknown Regions at that point in time — in the centuries before the Great Hyperspace War with the Galactic Republic . A system with a radius of several million kilometers , it contained an orange - colored star that was orbited by the planet Nathema , a fertile agriworld originally known as Medriaas . However , the system was marked by the absence of the Force itself . History . Colonized by the Sith species well before the year 5113 BBY , the Nathema system was within the territory of the Sith Empire and therefore supplied the Empire with foodstuffs produced by the many villages on Medriaas ' surface . However , the ruling Sith Lord Dramath was overthrown by his young illegitimate son Tenebrae , and the thirteen - year - old boy was granted his father ' s throne in 5100 BBY by the current Dark Lord of the Sith and ruler of the Empire , Marka Ragnos . Renaming his world Nathema , the newly - appointed Lord Vitiate kept the Nathema system largely unaffected by traditional Sith infighting during the century of his rule , and when the Great Hyperspace War began with the Republic in 5000 BBY he chose to keep himself and Nathema out of the fighting . As a result , Nathema escaped the widespread destruction that wracked the Empire in the aftermath of the Republic ' s victory , and Vitiate summoned all of the remaining Sith Lords to Nathema in 4999 BBY with the promise of the Empire ' s salvation and the destruction of the Republic ' s hated Jedi protectors . However , Vitiate instead took mental control of the eight thousand Sith who answered his call and forced them to participate in a dark side ritual that stripped the very life from the entire planet , leaving Nathema literally lifeless except for Vitiate . Blaming the destruction of his planet on the Jedi Order , Vitiate led the remnants of the shattered Empire on a twenty - year exodus that ended with the rediscovery of the lost colony Dromund Kaas . Declaring himself Emperor of a reconstituted Sith Empire , Vitiate purged all hyperspace navigational data that related to the Nathema system , ensuring that none of his new subjects could return to the system and discover the truth . However , sometime before 3954 BBY , several members of the new Empire ' s ruling Dark Council had discovered the Nathema system and the Emperor ' s past , and they formed a plot to unseat him . In 3960 BBY , the Jedi Knights Revan and Malak discovered the Nathema system while searching for the mysterious Sith influence that had manipulated the Mandalorian warrior culture into declaring war on the Republic , and the pair ' s visit to Nathema drove them to try and kill the Emperor once they discovered the route to Dromund Kaas . However , the Emperor broke the two Jedi and sent them back to the Republic as his servants , though the pair broke free of his control and declared their own empire . Revan was wiped of his memories and retrained as a Jedi by the Jedi Council during the subsequent Jedi Civil War , but after he defeated Malak in battle and ended the conflict , he began to be plagued by his broken memories and eventually rediscovered the path to Nathema . At the same time , the Dark Council or Darth Nyriss inducted the Sith Lord Scourge into the conspiracy by showing him Nathema , and the pair were departing the system when Revan arrived in his ship the " Ebon Hawk " . Nyriss and Scourge shot down the " Ebon Hawk " with an ion cannon and captured Revan , but his utility droid companion T3 - M4 was able to repair the " Hawk " over the next few years and return to the Republic . T3 - M4 returned to the Nathema system with Revan ' s friend and ally Meetra Surik in 3950 BBY , and the two were able to locate a hyperspace route to Dromund Kaas within the remains of Nathema ' s governmental database . Besides these sporadic visits , the star system remained unknown and barren , and its location at the edge of the galaxy did little to attract the attention of major galactic powers throughout the following centuries . During the New Sith Wars , a conflict between the Republic and various Sith factions , the Nathema system was located within contested space , and it remained unaligned or contested throughout the next several centuries until the year 137 ABY , by which point the Galactic Empire under the Sith Lord Darth Krayt had taken control of that region of the galaxy . Orbital bodies . Nathema . Nathema , originally known as Medriaas , was a primitive agriworld colonized by the Sith species that supplied the Sith Empire with foodstuffs in the years before the Great Hyperspace War . The planet supported a significant population of farmers scattered across its surface in villages and the occasional city , but the Ritual of Nathema completely eliminated all life on the planet . Vitiate ' s ritual tore the Force itself from the environment , leeching color and sound and leaving everything a dull brown or gray color as well as causing Force - sensitive individuals physical illness on account of the Force ' s absence . Behind the scenes . The Nathema system first appeared in Drew Karpyshyn ' s 2012 novel " " , though it was not explicitly identified as the Nathema system until an update to the of the 2009 reference guide " The Essential Atlas " placed the system in the Chorlian sector , with grid coordinates S - 4 . The book places the Nathema system in the Unknown Regions , though neither the novel nor the Companion specifies whether the Nathema system was also renamed when Medriaas was .
