Kel'sara served as a commander within the [Dread Host], and she was a humanoid female. During the [Galactic War] that pitted the Galactic Republic against the reconstituted Sith Empire, she participated in the conflict. Alongside Heirad and Ciphas, she was among the troops that traveled with Kephess to Asation. The three of them were slain in combat as they defended the route leading to the Grand Hypergate, specifically within the Quadrilateral Forum. In combat, she used a double-bladed lightsaber that emitted a yellow blade.
In the video game Star Wars: The Old Republic, Kel'sara, together with Ciphas and Heirad, are featured as a group, acting as the second boss encountered in the Operation titled "Terror From Beyond."
