Gloom Walkers 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 . From the years 1003 BBY to 1002 BBY , the unit participated in scores of battles , including ones on Kashyyyk , Trandosha , and Phaseera . In 1002 BBY , the unit fought in the Battle of Phaseera , where Dessel staged a mutiny , knocking out Ulabore and taking command of the unit . Dessel led the Gloom Walkers to capture a critical Republic outpost , where he killed a large number of Republic soldiers even after being blinded by a flash canister . His incredible feats during the battle were reported to the Brotherhood of Darkness , who took him away for training in the dark side of the Force . Afterward , the trooper Lucia killed Ulabore during a skirmish on Alaris Prime in revenge for the arrest of Dessel . History . Battle of Kashyyyk . The Gloom Walkers , under the command of Lieutenant Ulabore , was one of many military units in the Sith army during the New Sith Wars against the Galactic Republic . In the year 1003 BBY , the unit welcomed two new members — a former cortosis miner named Dessel and Adanar , who were placed in the unit on the same day . Over that next year , the Gloom Walkers were in scores of battles on half a dozen worlds , earning them a reputation as an elite unit . Dessel and Adanar saw their first action with the Gloom Walkers in the battle of Kashyyyk , where the Sith tried to secure a foothold in the Mid Rim by invading the Kashyyyk system . The Republic forces were firmly entrenched within the great forests of the planet , and the battle turned into a war of attrition fought among the branches of the wroshyr trees . The Sith trooper s , unused to fighting in such heavy foliage , were annihilated by the Republic soldiers and their native Wookiee guides . The Gloom Walkers were part of the second wave of reinforcements . During the battle , they were separated from the main lines of battle , cut off from the rest of the Sith army . Lieutenant Ulabore panicked and had no idea what to do to keep his unit alive without direct orders while alone and surrounded by enemies . Dessel was there to save his unit , being able to somehow sense where the enemy was even when he could not see them , and helped the Gloom Walkers avoid Republic traps and ambushes as they worked their way back to the main force . The march back to the rest of the Sith army took three days and nights , and several members lost their lives during countless clashes with the Republic forces . Upon returning to the main force , their story became a rallying point for the rest of the Sith army and raised morale that had become dangerously low . The Sith eventually won the battle and captured Kashyyyk , and Ulabore was given a special commendation as the unit ' s commander , although he failed to mention that it was Dessel who was responsible for leading the Gloom Walkers back to the main force . However , Ulabore promoted Dessel to the rank of sergeant . Battle of Hsskhor . After the battle of Kashyyyk , the surviving Republic soldiers fled to the neighboring world of Trandosha , and twenty units of Sith troopers , including the Gloom Walkers , were sent in pursuit . They caught up to the Republic survivors in the desert plains outside of the city of Hsskhor , and the Battle of Hsskhor ensued . After a day of savage fighting that had left many dead on both sides , the Republic and Sith forces retreated to opposite ends of the battlefield to regroup . However , the native reptilian Trandoshans struck several hours later . As the Trandoshans were not allied on either side of the New Sith Wars , they attacked both sides , using their ability to see into the infrared spectrum to fight in the pitch - black night . Both the Sith and Republic soldiers , including the Gloom Walkers , were caught completely off - guard , and by the end of the night nearly half of the Sith troops had been killed . In retaliation , Sith reinforcements were sent in from Kashyyyk . The Trandoshans and the Republic forces were overwhelmed in less than a week , with many of the Trandoshans giving up on defending their homes , switching sides and fighting with the Sith . In the end , the city of Hsskhor was sacked and razed to the ground . Battle of Phaseera . By 1002 BBY , the Gloom Walkers had turned from one of a thousand expendable front - line units into an elite group reserved only for critical missions . That year , they participated in an attack on the Republic manufacturing world of Phaseera . Upon landing on the planet , the Gloom Walkers were tasked with eliminating a Republic outpost ; its elimination would allow the rest of the Sith army to launch a surprise attack on the Republic base camp . Lieutenant Ulabore believed that the Gloom Walkers ' mission would be easy , which relaxed the troopers as they waited for their orders . However , Dessel had a bad feeling about the battle to come , much like he had felt before the near - disaster at Hsskhor . Eventually , Ulabore returned with their orders — they were to hit the outpost in one hour . This was met by shock and outrage from the soldiers , one of whom shouted out that it was a suicide mission . Dessel reasoned that the outpost ' s three repulsorcraft equipped with heavy - repeating flash cannon s would mow them down from the sky if they tried to take the outpost during the day . Ulabore refused to listen to the Gloom Walkers ' protests , and Dessel simply punched Ulabore in the jaw , knocking him out , and took over command of the unit . Dessel ordered the communications officer to tell the Sith headquarters that their mission was complete so they could start moving the main force into position , giving the Gloom Walkers two hours to accomplish their objective . After knocking out Lieutenant Ulabore , Dessel addressed the Gloom Walkers , stating that anyone who followed him from there on in could face a court - martial and if any of them felt they could not follow him after what he did he would surrender command to Adanar . However , the Gloom Walkers voted to stay under his command . Under the cover of night , the Gloom Walkers moved silently through Phaseera ' s jungle until they had it surrounded , splitting into three squads on three sides of the outpost . Once they were in position , they activated their interference box es , jamming all transmissions within their perimeter . However , they ran into an unexpected problem ; although the repulsorcraft were grounded , each of them still contained a soldier operating the flash cannons . Dessel proposed that Lucia , one of the unit ' s best shots , snipe the three gunners in succession , but the idea was rejected as impossible . Frustrated and acting on instinct , Dessel shot two of the gunners , but was blinded by a flash canister . Incredibly , Dessel was still able to see even after being blinded , and quickly killed all the soldiers manning the gunships . Three hours later , the outpost had been taken , with nine Gloom Walker casualties . Dessel left Adanar and a small contingent to hold the outpost , and he and the rest of the Gloom Walkers returned to their camp to find Ulabore , by now fully conscious , accompanied by a dozen Sith enforcers . The enforcers took Dessel to be court - martialed , but before he could be put on trial , he was taken away to the Sith academy on Korriban , his Force - sensitivity having been recognized . Indeed , his connection to the Force had allowed him to lead the Gloom Walkers back on Kashyyyk and to kill the soldiers at the outpost . Eventually , Dessel became Darth Bane , one of the most influential Dark Lords of the Sith in galactic history . However , Dessel ' s arrest disturbed many troopers of the unit , especially Lucia . A month later , as the Gloom Walkers were deployed to Alaris Prime , they stumbled into a Republic ambush — something Lucia knew would never have happened had Dessel still been with them . During the brief ensuing skirmish , Lucia betrayed and killed Ulabore , shooting him in the back , in revenge for the arrest of Dessel , as she believed the sergeant had been court - martialed and killed . The Gloom Walkers quickly defeated the Republic troops and approved of Lucia ' s actions ; they never reported her betrayal , and Ulabore was registered as killed in action . Members . Ulabore . Lieutenant Ulabore was the official leader of the Gloom Walkers and won much praise and accolades from his superiors for the unit ' s success , despite the fact that the Gloom Walkers ' success was due more to Dessel ' s leadership than Ulabore ' s . Ulabore was blindly loyal to the Brotherhood of Darkness , the commanding force of the Sith army , and was afraid of going against their wishes . He was a cowardly and ineffective leader , and panicked when cut off from the main force on Kashyyyk which caused Dessel to take over . His troops openly mocked him , knowing that Dessel was really the one in charge . Despite Dessel ' s distinguished service in the Gloom Walkers , Ulabore still talked down to him and treated him and the other troops as inferior . Ulabore ' s fear of disobeying his superiors was displayed during the Battle of Phaseera , when he refused to break the orders given to him , despite the fact that it was a suicide mission . Ultimately , Dessel forcibly removed him of command and completed their objective . Ulabore ' s arrest of Dessel caused the other members of the Gloom Walkers to resent him , and eventually led to Lucia betraying and killing him on Alaris Prime . Dessel . Dessel , a former cortosis miner from the planet Apatros , joined the Sith army and was placed in the Gloom Walkers unit on the same day as fellow trooper Adanar . Dessel was a Force - sensitive , a trait that helped the unit in several missions ; in the Battle of Kashyyyk , he was able to sense and avoid Republic traps and ambushes while leading the Gloom Walkers back to the main force , and on Phaseera he was able to kill nine Republic soldiers even after being blinded by a flash canister . Although Ulabore took full credit for the events on Kashyyyk , he promoted Dessel to sergeant . Dessel was widely regarded as the true leader of the Gloom Walkers , and all the other members listened to him instead of Ulabore . During the Battle of Phaseera , Dessel became fed up with Ulabore ' s ineffective leadership and knocked him out , taking over command and leading the Gloom Walkers to complete their objective . His seemingly impossible feats during the battle were reported by Lucia to the Brotherhood of Darkness , and he was taken away for training in the dark side of the Force . Dessel eventually became Dark Lord of the Sith Darth Bane , but would never forget his time with the Gloom Walkers . Adanar . Adanar was a senior Sith trooper , and the Gloom Walkers ' third - in - command behind Dessel and Ulabore . Adanar enlisted in the Sith military on the same day as Dessel , and the two grew to be good friends . After basic training , the two were placed in the Gloom Walkers together , and Adanar grew to admire Dessel . Upon taking the Republic outpost during the Battle of Phaseera , Adanar and a small contingent were left there to hold the outpost while Dessel returned to camp . Lucia . Lucia was a junior officer and sniper with the Gloom Walkers , one of the youngest soldiers in the unit . Before the Battle of Phaseera , Lucia had not seen much action , but had come to be regarded as one of the better shots in the Gloom Walkers . After witnessing Dessel ' s seemingly impossible feats in the battle , Lucia told their Sith superiors of Dessel ' s abilities , causing him to be recognized as a Force - sensitive . She was very loyal to Dessel , and after his arrest , Lucia felt dissent toward Ulabore . During a skirmish with Republic troops on Alaris Prime , Lucia betrayed Ulabore and shot him in the back , killing him . After the war and the dissolution of the Gloom Walkers , she became a prisoner of war and was placed on a work planet , until the Senate released an official pardon to all troopers who had served the Sith . She eventually found work as a mercenary , bounty hunter , and finally a bodyguard for Princess Serra until her death . Behind the scenes .
