Sarro Xaj Sarro Xaj was a Human male Jedi Knight who had a massive physique and studied under Master Raskta Lsu , and fought alongside her in the New Sith Wars on Ruusan . He was promoted to the rank of Jedi Knight around 997 BBY and followed in her footsteps , training to become a Jedi Weapon Master . Biography . Xaj joined Raskta Lsu , Worror Dowmat , Valenthyne Farfalla and Johun Othone on the " Justice Crusader " to Tython , in pursuit of the Sith Lord Darth Bane and his apprentice Zannah . Once they arrived at Belia Darzu ' s castle , they immediately engaged in a duel with Darth Bane and Darth Zannah . Xaj wielded a blue double - bladed lightsaber nearly three meters long and attacked Zannah in concert with his fellow Jedi Othone . Unfortunately , Othone ' s lack of skill actually hindered Xaj ' s efforts . As Xaj pressed his offensive he was interrupted by Othone ' s basic strikes and was forced to pull up his attacks in order to avoid killing his companion . At one point in the battle , Farfalla called for reinforcements and Xaj shouted for Othone to help him , leaving Xaj to duel Zannah alone . Xaj was able to overpower Zannah in one - on - one combat , using the Force channeled through him by Worror ' s battle meditation . He exhausted his opponent with his superior strength and drove her back into a corner . As he moved to finish her off , Worror ' s concentration was broken and his battle meditation cut off , robbing Xaj of the power afforded to him by the Ithorian Jedi Master . Xaj hesitated and glanced toward his companions to see what had happened . Zannah used the opportunity to assault Xaj ' s mind with Sith sorcery and then killed him with a blow to his chest . Legacy . Following his death on Tython , the Jedi High Council , alerted to the existence of Darth Bane by Caleb of Ambria sent a team of Jedi , including Masters Tho ' natu and Obba to destroy him . On Ambria , in Caleb ' s camp , the Jedi discovered the lightsaber hilt s of the slain Jedi , including Xaj ' s . Upon the team ' s arrival they were assaulted by a deranged Darovit , whom they assumed to be Bane suffering from overexposure to the orbalisk armor . Slaying him , they deemed that the Sith were extinct , and returned the lightsaber hilts to the Temple . Once returned to the Temple , the Jedi created a memorial to those Jedi who were responsible for the destruction of the Sith . All five Jedi ' s lightsaber hilts were set into a large white stone block in the gardens around the base of the Tower of First Knowledge . Under each hilt was a depiction of its wielder , along with their name . Personality and traits . Sarro Xaj was a massive man , standing over two meters tall and weighing 150 kilograms . He had olive brown skin and a single topknot of black hair . In his youth , Xaj ' s passion for lightsaber combat was enough to catch the eye of Weapons Master Raskta Lsu . He was confident in his abilities , humorously speculating that the upcoming battle with the Sith Lords on Tython might be too easy . He even smiled at Zannah in the midst of combat once he was able to engage her in a duel alone , free of the encumbrance of Othone . Powers and abilities . As a Padawan , Xaj chose to follow his master ' s footsteps in seeking to perfect his skills with a lightsaber . He joined his master in the Ruusan campaign and a few years after the end of the New Sith Wars Lsu completed his training , deeming him worthy of the rank of Jedi Knight . Eventually he earned the rank of Weapons Master . His skill with a double - bladed lightsaber was enough to overwhelm Darth Zannah in one on one combat with the aid of Worror ' s battle meditation . Zannah described Xaj ' s fighting style as having more refinement than Bane ' s . Once the effects were cut off he was distracted and was unable to defend himself from Zannah ' s Sith sorcery , resulting in his death .
