Biography . Viun Gaalan was a male Keshiri from the planet Kesh . Gaalan was also Force - sensitive , and his ability to manipulate its dark side , combined with his unblemished physical appearance , eventually earned him the rank of Sith Lord within Kesh ' s Lost Tribe of Sith . Mission to Dathomir . In 43 . 5 ABY , Lord Gaalan was a member of a team that was sent by the Lost Tribe to the Dathomir system to retrieve the stranded Sith apprentice Vestara Khai . Khai was the sole survivor of a strike force that had been recently dispatched to the Maw black hole cluster on a mission to kill Luke Skywalker , the Grand Master of the Jedi Order . She fled to the planet Dathomir , made contact with the Tribe , and made plans for them to rescue her . Khai had also arranged for a group of Nightsister witches to be collected by Gaalan ' s team for transport back to Kesh . At the appointed time , Gaalan led a vanguard of shuttles to Dathomir ' s surface , where he was introduced by his aide to Dresdema , leader of twenty - two Nightsisters and eighteen of their pet rancors . The witches were expecting all of the Sith to be female and perceived Gaalan ' s obviously male identity as an act of treachery . Dresdema gave an order for her sisters to attack , forcing Gaalan and the Sith into battle . He immediately set upon the nearest rancor , using the Force to propel himself onto the beast ' s shoulder . He then decapitated the rancor with his lightsaber , while his companions killed the remaining rancors and incapacitated all of the Nightsisters . Duel with the Grand Master . As the witches were being bound and taken to the shuttles , Gaalan was approached by Vestara Khai , who advised the Sith Lord of an additional Nightsister whom she had captured . Gaalan praised her and took from her a datapad that held the coordinates to the Maw Cluster , the home of a mysterious dark side being whom Khai had encountered while in pursuit of the Jedi . He then allowed the apprentice to recover her captive but was confronted shortly thereafter by Luke Skywalker and his son , Ben — who had followed Khai to Dathomir — and their Force - sensitive comrade Dyon Stadd . After he introduced himself to the elder Skywalker , Gaalan declared that he would be the agent of the Jedi Grand Master ' s death , and would also exact revenge on behalf of Lady Olaris Rhea , whom Skywalker had killed at Sinkhole Station . When the Jedi dismissed Gaalan ' s proclamation , the Sith Lord ignited his red - bladed lightsaber and lunged at his opponent . His aide joined him in the assault against Skywalker , but Gaalan soon found himself alone against the Jedi Master , as his aide was knocked aside . His aide and the two other Sith , a male and a female Saber , then engaged Stadd and Ben Skywalker during the fight . Gaalan matched Skywalker blow - for - blow , but the other Sith quickly fell to Ben Skywalker and Stadd . As Khai returned to the scene to aid the Sith , Gaalan capitalized on a moment of Skywalker ' s distraction to retreat to the safety of his shuttle . He immediately closed the hatch and sped away while using the Force to telekinetically counter and nullify Skywalker ' s Force grip on the shuttle . Personality and traits . Viun Gaalan was a tall , lean , broad - shouldered , lavender - skinned Keshiri male who possessed a physical beauty that was highly respected by the members of the Lost Tribe . Indeed , his flawless features contributed to his ascension to the rank of Sith Lord , which was a common occurrence among the upper echelons of the Sith . Women such as Vestara Khai and the Nightsister Dresdema considered him exceedingly attractive , although the latter was not so moved by his appearance that she felt obliged to abandon the Dathomiri belief in feminine superiority . Gaalan spoke with a cultured , rich , and melodious voice that was unnervingly pleasant , and conveyed an air of preeminence . He regarded the Nightsisters as savages and was disappointed with being assigned to escort them back to Kesh . He did little to acknowledge the presence of Sith apprentices such as Vestara Khai , and like other Sith Lords , his face remained expressionless during casual conversation , even in the midst of joking . Gaalan did , however , voice his approval of Khai ' s actions and openly commended her success upon their meeting in the Dathomir landing meadow . He nevertheless considered Khai expendable and chose to ensure only his own survival when he escaped to his shuttle and left Khai to the mercy of the Jedi . Gaalan was interested in achieving greater status within the Lost Tribe and believed such honor would be bestowed upon him were he able to kill Luke Skywalker . He also actively sought to avenge the death of Lady Rhea by ending Skywalker ' s life , but he was unsuccessful in completing that goal . Powers and abilities . Viun Gaalan displayed notable ability with his red - bladed lightsaber , using it to behead a rancor in one fell swoop . His dueling prowess was slightly inferior to Grand Master Skywalker ' s , whose blade came increasingly close to striking the Sith Lord , before Gaalan was forced to flee . Skywalker believed that while Gaalan ' s combat skills were probably enough to contend with Jedi swordmaster s such as Kyp Durron or Kyle Katarn , he would have been more than a match for the reserved dueling style of the Mon Calamari Master Cilghal , or even Skywalker himself , had the Grand Master had to face Gaalan immediately after his time beyond shadows in the Maw . Gaalan also demonstrated considerable strength in the Force and used it to perform feats of great acrobatic skill . He was able to leap to great heights when fighting a rancor before alighting with flawless balance . He was also able to telekinetically resist and counter the Force grip of Luke Skywalker while escaping in his shuttle . Behind the scenes .
