However , Callef was killed in a duel with another Jedi apprentice who came to rescue Aharo . Biography . A Force - sensitive male Human , Callef became the apprentice of the Dark Jedi Bengel Morr sometime before 3643 BBY . Morr , the Nautolan apprentice of the Jedi Master Orgus Din , had disappeared during the Sacking of Coruscant in 3653 BBY by the Sith Empire , and he had gone insane over the course of the next ten years . Morr taught Callef that the Jedi Order had become weak and useless , and that it should be destroyed and rebuilt into something stronger . Around 3643 BBY , Callef and Morr made their move on the Jedi homeworld of Tython . In their quest to overthrow the Jedi Order , he and his master instigated an uprising amongst the native Flesh Raider s , and used the bestial natives as soldiers while they directed from the shadows . Using a secret tunnel connecting the Tythos Ridge and the Tythonian Gnarls , Callef led an invasion force of Flesh Raiders into the Gnarls against the Jedi ' s base there . A Bith Jedi apprentice by the name of Unaw Aharo had noticed the increased Flesh Raider activity in the area and reported his findings to Jedi Master Derrin Weller . However , Aharo was captured by Callef ' s forces not long after sending his message , and they brought the wounded and disarmed Bith before the Dark Jedi in the cave . Callef began to question Aharo , who was shocked to see that the Human carried a lightsaber . However , a young Padawan interrupted Callef before he could kill the Bith , having defeated the Flesh Raider soldiers who had been guarding the cave . The Jedi apprentice ' s martial skill sparked the Dark Jedi ' s interest , but Callef was confident in his abilities and summoned two Flesh Raider guards , attacking the Padawan . Despite having only a vibrosword against the Dark Jedi ' s lightsaber , the apprentice fought and defeated Callef in a duel , which ended with Callef ' s death . Legacy . After his death , Master Orgus Din arrived and sealed the cave after he recovered Callef ' s lightsaber . Remarking on the strange familiarity of the weapon , Din escorted Aharo to a medcenter and ordered the other Padawan to report to the Jedi Temple . Later on , the Padawan would be contacted by Callef ' s master Bengel Morr , who expressed his disappointment that Callef was defeated so easily . However , Morr was not overly concerned , as he doubted the Padawan would be able to defeat him and stop the Flesh Raider invasion . Personality and traits . A Force - sensitive Human male , the fair - skinned Callef had brown hair and eyes . He was fluent in Basic and able to understand the language of the Bith people , as well as the guttural language of the Flesh Raiders . Callef was arrogant and cruel , believing in survival of the fittest , and he despised what he saw as passivity and weakness on the part of the Jedi Order . Like his master Bengel Morr , Callef desired the destruction of the Jedi Order so that the pair could rebuild it in accordance with their own beliefs . The Padawan who killed Callef later remarked to Grand Master Satele Shan that Callef seemed calm — the apprentice could feel no anger or fear in the Dark Jedi , despite his use of the dark side . As Bengel Morr ' s apprentice , Callef wielded a blue - bladed lightsaber that he based off of his master ' s own weapon . When Orgus Din — Morr ' s former master — recovered Callef ' s saber from the Dark Jedi ' s body , he was startled by the weapon ' s familiarity , though he could not remember that of which it reminded him .
