Isk, a humanoid who was Force-sensitive, lived as a slave under the Infinite Empire. From the time he was born, the Rakata trained him to be a Force Hound. Serving Predor Skal'nas, Isk met his match in the Arena of Byss when he was bested by Xesh in a deadly battle. He pleaded with Xesh to end his life, but Xesh would not. Following this, Skal'nas commanded that Isk be put to death and made ready to be eaten.
