Biography . Enslaving others . Xor , a Twi ' lek male , was a Mandalorian slaver who lived during the time period after the Great Sith War . When the Mandalorians under the command of Cassus Fett , who orchestrated the battle , attacked the planet Cathar in 3973 BBY , Xor participated by fighting and killing many members of the local Cathar species . As he did , the Twi ' lek took pleasure in the carnage , due to his hatred of the Cathar people . Although the Mandalorians nearly wiped out the Cathar , Xor sustained injuries during the battle that prevented him from participating in combat . Twenty years later , Xor was involved in the Mandalorian Neo - Crusaders ' invasion of the planet Taris during the Mandalorian Wars . At some point after that , Xor encountered and murdered a Cathar male in the Lower City , although his wife and daughter , Juhani , were able to evade the Twi ' lek . Two years later , Xor saw Juhani and attempted to buy her from the auction blocks on the world . Before he could do so , the Jedi forces under the command of the Jedi Knight Revan liberated Taris , freeing Juhani from slavery . Confronting Juhani . In 3956 BBY , during the Jedi Civil War between the Republic and Darth Malak ' s Sith Empire , Xor encountered Juhani , who was now a Jedi , as she was aiding Revan — who was formerly a Dark Lord of the Sith and was now a retrained Padawan — in his search for the Star Forge , a Rakata n space station that was fueling the Sith war effort against the Republic . During his conversation with Juhani and Revan , Xor insulted the Cathar by trying to convince Revan to sell her to him . After Revan refused and Juhani threatened to kill Xor for his actions against her people , the Twi ' lek vowed to confront them again and capture Juhani . Xor and two cronies eventually ambushed and attacked Revan and Juhani near the former ' s starship " Ebon Hawk " . However , the Twi ' lek was mortally wounded by the Jedi , and his thugs were defeated . As Xor was dying , he tried to goad Juhani into striking him down , but Revan helped keep her from giving into her anger by reciting the first precept of the Jedi Code , which denied emotions and encouraged peace . Xor then died , angered that his death was ignoble . Personality and traits . Xor had purple skin and eyes and used a blaster rifle during combat . He hated the Cathar species and desired to eradicate or enslave them , and was among the Mandalorians who attacked the world for the pleasure of destroying it . He also viewed Cathar slaves as pets that were kept for the amusement of their owners , which left him with zero redeeming qualities . Although he was injured during the battle on Cathar , he continued to fight with the Mandalorians . Xor killed Juhani ' s father when he ran across him on Taris , and was prepared to purchase Juhani on the auction blocks during the Mandalorian occupation on Taris . When he later encountered Juhani and Revan during the Jedi Civil War , Xor talked disparagingly to Juhani and taunted her , even going so far as to ask Revan if he wished to sell her to him . After Revan and the Cathar defeated him during his attempt to capture her , Xor attempted to pressure Juhani to give in to her hatred and murder him . He also resented the Jedi for their role in hindering his acquisition of slaves during the Mandalorian Wars . Behind the scenes .
