The Fist was a Sith Lord who served as the supreme military commander for the One Sith. The Fist was appointed to the position by Darth Krayt. Until 130 ABY, the Fist was Darth Nihl, but he was then made into a Hand after his predecessor was killed at the Massacre at Ossus. As of 137 ABY, Darth Stryfe served as Krayt's Fist, in command of the Service alongside Grand Admiral Morlish Veed.
