The Gloom Walkers was a unit in the Sith army during the New Sith Wars in the years leading up to the Seventh Battle of Ruusan. The Gloom Walkers were commanded by Lieutenant Ulabore. During the New Sith Wars, the Gloom Walkers went from an expendable front-line unit to an elite group reserved for important and difficult missions due to a high success rate, which was largely due to the efforts of one of their troopers, Sergeant Dessel. Dessel was a Force-sensitive, and his latent Force abilities guided them to many victories.
