"I don't care who's representing you. I'm not here to negotiate."
Kilran to the Esseles crew

Rycus Kilran was a human male who served as Grand Moff of the Sith Empire during the Cold War and the Galactic War. He was best known for his role during the Sacking of Coruscant

, which earned him the nickname of the "Butcher of Coruscant".
Cultured, cunning and utterly ruthless, Rycus Kilran may be the greatest naval strategist the Empire had ever seen. Born to a wealthy family with a proud military tradition, Kilran proved himself a capable right-hand man to the Sith during the Empire's early assaults on the Brema Sector. When his Sith superior died during the Battle of Ord Ibanna, however, Kilran showed that he was more than an able tactical advisor - he assumed command of the ragged Imperial fleet and led it to a swift and decisive victory.
In the years that followed, Kilran's authority grew with his list of triumphs, and both the Sith and the Minister of War learned respect for his unorthodox strategies. His brutally effective strikes during the final days of the war earned him the nickname "the Butcher of Coruscant" among Republic civilians (a name he adopted with characteristic irony), and his heroic stand against a Jedi boarding party earned him his scars. After the war ended, he was granted the honorary title "Grand Moff" in recognition of his contributions.
Shortly before the end of the Cold War, Kilran led an unsuccessful covert operation
