Chagras was a Human male Sith Lord who lived during the time of the Republic Dark Age . He was one of seven children of Vilia Calimondra , a Sith Lord who controlled a large empire in the Grumani sector , and he made a claim to become the heir to Calimondra ' s holdings . However , his siblings all made similar claims , so , in 1066 BBY , Calimondra instigated the " Charge Matrica " , a contest designed to determine which of her children would be appointed as her beneficiary . She tasked her children with expanding her holdings , planning to make her heir the individual who expanded her territories the most , and , for a time , the siblings cooperated . However , after her bid began to flounder , Chagras ' sister Xelian declared war on him , causing all of the siblings to initiate hostilities against each other . Through his cleverness , Chagras was able to gain control of large regions of space , forging a Sith state known as the Chagras Hegemony . At some point , he developed the Death Spiral , a type of automated ground attack vehicle , and he constructed several of them . He fathered a daughter , Arkadia Calimondra , and he also became an uncle to his siblings ' various children , including Xelian ' s sons , Daiman and Odion . In circa 1046 BBY , he became a father again , to the twins Dromika and Quillan . Eventually , Chagras was the only one of Vilia Calimondra ' s children left , and he became her heir at some point circa 1050 BBY . His victory brought a period of stability to the Grumani sector and guaranteed Chagras the assistance of his nieces and nephews , so he tasked them with repairing the damage that the war had caused his holdings . By 1042 BBY , he was strong enough to turn his attention to the worlds of the Galactic Republic , outside the bounds of the Grumani sector , and he dispatched Odion to sack the University of Sanbra , a famed educational establishment situated on the planet Sanbra . Shortly afterward , on the orders of Calimondra , Chagras sent Odion to conquer the Republic - held world Aquilaris . Odion massacred most of the world ' s inhabitants , and Chagras eventually intervened and prevented his nephew from killing all of the planet ' s population , so that some of the people could be used as slaves , to operate Aquilaris ' s fleek eel traps . Odion secretly captured some University of Sanbra researchers from Aquilaris to help him to track down the Helm of Ieldis , a powerful Sith artifact , and he suspected that the real reason why he had been sent away was because Chagras suspected something . Late in his reign , Chagras annexed the agrarian planet Chelloa , and he relocated much of the world ' s population to the frontier regions of the Chagras Hegemony to fight for him . However , before many more planets could fall to the Sith , Chagras was killed under unexplained circumstances , in 1040 BBY , by a powerful nerve toxin . Following Chagras ' death , custody of Dromika and Quillan passed to the Krevaaki Saaj Calician , a Sith Lord who had previously served under Chagras . Vilia Calimondra began a second " Charge Matrica " to find a replacement heir from among her grandchildren , and they soon went to war against each other , shattering Chagras ' former holdings into more than ten different parts . However , a small region of his territories held out from the invaders and became known as the Chagrasi Remnant . In circa 1032 BBY , the Jedi Master Vannar Treece compiled a report on the state of affairs in the Grumani sector , and in it he detailed Chagras ' rise to power and subsequent death . Around this time , Arkadia initiated a plot to avenge her father ' s death by murdering Vilia , whom she believed had arranged for his demise . Arkadia theorized that her grandmother had organized the " Charge Matrica " as a way of keeping the Calimondra family focused on fighting each other , rather than plotting against their matriarch , and that Vilia had lived in fear of assassination once Chagras had won the contest . Arkadia arranged to send the Bothan Narsk Ka ' hane to kill Vilia using Chagras ' s Blood , a type of nerve toxin created from Synedian algae . However , Ka ' hane was secretly an agent of Vilia , and Arkadia ' s plot was unsuccessful . Personality and traits . Chagras was a clever individual , and many refugees considered Chagras ' rule to be preferable to life under some of the sector ' s other Sith . He doted on Dromika and Quillan , and they found it difficult when he died . Chagras had the ability to use the Force to heal himself , but the nerve toxin that killed him was too effective for his powers to overcome . Behind the scenes . Chagras was created by John Jackson Miller and first mentioned in " Knight Errant 0 " , a preview issue of the comic series " " , which made reference to the " Chagras Hegemony . " In November 2010 , he received another mention , in The " Knight Errant " Gazetteer , an article that was written by Miller , Daniel Wallace and Jason Fry , and published on StarWars . com . The article was the first source to identify Chagras as a distinct individual , and it clarified the nature of his relationship to the Chagras Hegemony . He was later referenced in the " Knight Errant " novel , which was written by Miller and released in January 2011 , and he received further mentions in the and issues of the comic .
