Kels, a Human of the male variety, held the position of chief engineer on the Dorin's Sky, which was a Thranta-class corvette serving within the ranks of the Republic Navy. In the course of the Galactic War, the Dorin's Sky experienced a boarding action by forces of the reconstituted Sith Empire, resulting in Kels' death as he fought to protect the ship's engineering section.
The character of Chief Engineer Kels is featured as a boss encounter within the Boarding Party Flashpoint, which is a component of the video game Star Wars: The Old Republic.
