Korus Korus was a Human male citizen of the Empress Teta system who served as the royal tutor of Satal and Aleema Keto , heirs to the Tetan throne . Continually berated by the young Ketos , Korus acted as a spy for Satal ' s father , Lord Keto , secretly reporting on the activities of his son and niece . When Korus ' eavesdropping was discovered by Satal and Aleema , who had since formed a Sith cult known as the Krath , they used their newfound dark side powers to make him believe that his tongue was transformed into an Adegan eel . In 3997 BBY , a mutilated Korus accompanied the Krath when they stormed the Tetan carbonite smelter that orbited Empress Teta and proclaimed themselves the new rulers of the Tetan worlds . He was then forced to reveal his oral deformity before falling comatose and was the only Tetan official to survive the ensuing massacre . Korus was later made to serve the Krath , who had also maimed him further by sewing his mouth closed . After an innocent mistake that resulted in the soiling of Aleema ' s gown , Korus was killed — burned alive with Sith magic . Biography . Royal tutor . Korus was a Human male citizen of the Empress Teta star system . He was employed by Lord Keto , Emperor of the Tetan Monarchy , as the tutor of the heirs to the throne — Lord Keto ' s Force - sensitive son and niece , Satal and Aleema Keto . From their childhood , Korus instructed them in royal tradition as well as basic education . During their time with Korus , the children learned the fairy tale of the Krath , a fabled magician - god whose story stayed with them into their adulthood . As Satal and Aleema grew into adolescence , Lord Keto and his sister Magda came to mistrust their children . As a result , Korus was ordered to spy on them and report on their activities . This spawned contemptuous feelings within Satal and Aleema for Korus , and from that moment on he was regarded as the backstabbing lackey of their parents . Nonetheless , Korus remained true to his mandate on both ends ; he continued to oversee the activities of his royal charges , while reporting his findings to their parents . Enter the Krath . In 3997 BBY , Korus allowed Aleema and Satal to travel unaccompanied to the Galactic Museum on the Republic capital world of Coruscant . Unbeknownst to him , their trip was borne out of their fascination for the dark side of the Force , and , more specifically , the history of the Dark Lords of the fabled Sith Order . The Ketos discovered Sith magic on their journey and reinvented themselves as the Krath cult , so named after the fairy - tale magician - god of their youth . Korus was present for Satal and Aleema ' s return , and the Ketos , newly empowered with their Sith abilities , decided to enact their revenge against their royal tutor for conspiring against them with their parents . To prevent Korus from further tattling on them , his tongue was transformed into an Adegan eel by Aleema . The Krath had also sought to replace their parents as the governing body of Empress Teta and plotted a political takeover of the entire system . During Lord Keto ' s annual inspection of the orbiting Tetan Tetan carbonite smelter , Korus was forced to join the Krath as they stormed the space station , acting as their chaperone . He was well aware of the breach of protocol that was the Krath ' s presence during official matters of state , but he was unable to prevent it . As the Krath approached the gathering of Tetan officials , Korus was demanded by Lord Keto to explain his insubordination . Korus ' attempt at a reply brought him to the realization that he had an Adegan eel where his tongue should be , which mortified the Tetans and caused Korus himself to fall into catatonic shock . Fatal mistake . Korus regained consciousness to find that Lord and Lady Keto , along with the other Tetan officials and also those of the Carbonite Guild who were present on the orbital smelter , had all been executed by the Krath . With all opposition removed , the Krath claimed dominion over the Empress Teta system . Their base of operations was the Iron Citadel of Cinnagar , where Korus was reduced to waiting on Satal and Aleema hand and foot . For further amusement , Korus ' lips were sewn together by Aleema , and he was forced to serve his masters food and drink while acting as the object of their constant ridicule . His servitude did not last long , however . While carrying wine ordered by Satal for dinner , Korus stumbled and dropped the decanter , which broke and splattered the drink all over Aleema ' s new gown . Before Korus could clean the mess , she lashed out at him with the dark side and burned him alive , much to the amusement of those present . Korus ' death was the final one of the old Tetan regime , and his passing solidified the rule of the Sith - inspired Krath . Personality and traits . Korus was an elder man of gray hair and modest proportions , often regarded as fat by Lord Keto and his son . His passive demeanor was a direct contribution to the blatant disrespect shown to him by those around him , evidenced by the contempt repeatedly expressed for Korus by Lord Keto , Satal , and Aleema . The younger Ketos viewed Korus as a two - faced dotard and cast an illusion that replaced his tongue with an Adegan eel to prevent him from further serving as Lord Keto ' s double - agent . Korus was humiliated when his former students later sewed his mouth shut and forced him to wait on them as a manservant . His life was of no consequence to Aleema , who killed Korus accidentally in a fit of rage , yet expressed no remorse , instead reveling in the manner in which she had done it . Behind the scenes . The character of Korus ' initial appearance was in " " , written by Tom Veitch and Kevin J . Anderson . Korus also appeared in John Whitman ' s of Veitch ' s and Anderson ' s " " . Korus is given no actual speaking lines in either version , as he is introduced in both with his tongue having already been replaced with the Adegan eel . Instead he mumbles as one would with a full mouth , which can be identified in the audio drama .
