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.
