Biography . A Human male trained as a Sith Warrior , the Sith Lord Darth Acharon had ascended to the resurgent Sith Empire ' s ruling Dark Council by the end of the Cold War with the Galactic Republic . As a Dark Councilor , Acharon headed the Sphere of Biotic Science , one of the twelve Spheres of Influence within the Empire , and in that position he oversaw the branches of the Empire that dealt in medical science , cybernetic augmentation and physical enhancement — often in conjunction with Sith alchemy and magic . During his career as a Dark Councilor , Acharon quickly became known for his views on incompetence among the Imperial Military . The Sith ' s zero - tolerance policy regarding failure led him to personally execute over two hundred soldiers throughout his tenure , regardless of whether the soldiers had failed critical missions or simply worn their uniforms incorrectly . Those officers and troopers who volunteered to serve under him received even more detrimental treatment at Acharon ' s hands , as the Dark Councilor despised sycophants as well . Around 3641 BBY , Acharon and fellow Dark Councilor Darth Hadra traveled to the contested planet of Corellia to reinforce Darth Decimus , head of the Sphere of Military Strategy , in the war effort there . During the Battle of Corellia , Darth Acharon attended an eventful meeting of the Dark Council on Korriban via hologram . The meeting was originally called by Darth Baras , who attempted to declare himself the Voice of the Emperor to the rest of the Council , a position that would have granted Baras control over the entire Empire — but the Dark Councilor was killed by his former apprentice , the newly appointed Emperor ' s Wrath . Along with the rest of the Council , Acharon acknowledged the Wrath ' s autonomy and the fact that the Sith Warrior served a power greater than the Council ' s one . After the Wrath departed , Acharon ' s fellow Dark Councilor Darth Thanaton another matter before the council : he appealed to the other Councilors to destroy his rival and subordinate Lord Kallig , though the two dueled when the Council refused to fight Thanaton ' s battles . Acharon watched from Corellia as Kallig defeated Thanaton , and the Dark Councilors present on Korriban rewarded the young Sith with Thanaton ' s seat on the Dark Council . In the later stages of the battle , Acharon remained in the Governemnt District of Coronet City to guard the Ion Wall , a powerful weapon that could disable all electronics across a wide area . Cole Cantarus , an officer in the Corellian Security Force , briefly encountered Acharon during his time gathering information on the Imperial occupation forces . Cantarus ' info , combined with the help of Councilor Belos — a member of Corellia ' s ruling Council — allowed the Republic to learn the location of the Ion Wall ' s transmitters and direct them at the Legislature Building instead of Republic forces . A Republic strike team then stormed the Intra - Corellian Intelligence building to reach the Ion Wall ' s controls , cutting through the Imperial soldiers that Acharon had stationed in the building . As the strike team reached the weapon ' s control room , Acharon decided to execute the officer in charge of defending the building because of his failure and choked the commander to death with the Force before tossing the man ' s body across the room as a display of his power . The Sith Lord then questioned the invaders as to the identity of their spy , but when the strike team refused to answer Acharon drew his red - bladed lightsaber and attacked . However , the Dark Councilor was ultimately no match for the combined strength of the strike team , and the Dark Councilor was struck down in battle with the Republic fighters . Personality and traits . A Human male with orange eyes and extensive cybernetic enhancements , Darth Acharon ' s pale skin was turned ashen gray on most of his face by the corrupting effects of the dark side of the Force . The Sith Lord was famous for his extremely cruel views on failure and sycophants , and he had no qualms about killing soldiers who failed him in any way . Acharon also despised subordinates who attempted to gain favor with him , treating them with the same disgust that he did incompetents . Powers and abilities . Darth Acharon trained as a Sith Warrior and became proficient in both lightsaber combat and the use of the Force , skills that eventually led to his appointment to the Dark Council . He utilized both a single red - bladed lightsaber and offensive Force powers in battle , and his body was heavily augmented with cybernetic implants . Behind the scenes .

Players confront him in an attempt to take control of the Ion Wall weapon , and he is killed in battle . The 2012 reference guide " " identified Acharon as the head of the Sphere of Biotic Science .
