Duel on Hesperidium The Duel on Hesperidium was a vicious fight that occurred in the year 40 ABY , between Jedi Master Mara Jade Skywalker , and Lumiya , Dark Lady of the Sith . Having tracked Lumiya through the Force to the resort moon of Hesperidium , Skywalker engaged her fellow former - Emperor ' s Hand in combat , intent on eliminating the Sith for threats made against Skywalker ' s son Ben . Both women displayed their finesse with their weapons ; Lumiya with her signature lightwhip , and Skywalker with her own lightsaber . Skywalker quickly gained the advantage , managing to land several critical blows before she executed what she believed to be the killing blow . Lumiya ' s life was spared , however , when her recently - acquired Meditation Sphere intervened on her behalf to disable Skywalker . Reeling in surprise at the sudden and unexpected attack , Skywalker was helpless under the strength of Ship ' s attack , and watched in anger as Lumiya escaped her wrath yet again . It was only after a conversation with her son Ben did Mara realize she had been jumped by Lumiya ' s Ship , and that the Sith Lady was also secretly in league with Skywalker ' s nephew Jacen Solo , leader of the Galactic Alliance Guard . Prelude . Jedi Grand Master Luke Skywalker , and his wife Mara Jade Skywalker , were aware that Lumiya , self - proclaimed Dark Lady of the Sith , was actively spreading her dark side influence throughout the galaxy once again . Concern had also arisen between them that Lumiya was hunting their son , Ben , and was doing so through an inside connection to the Galactic Alliance Guard , the secret police of the Galactic Alliance . They even suspected that Lumiya ' s influence had spread so far as to enthrall their nephew Jacen Solo , leader of the GAG . Lumiya had indeed been in collusion with Solo ; however , when Mara questioned Solo about Lumiya ' s involvement in GAG affairs , he denied any such notion , while secretly becoming concerned that his aunt would soon discover the truth in her assumptions . Lumiya then devised a plan to draw the Skywalker ' s attention away from her apprentice Solo , by taking a pair of Ben ' s boots and leaving them outside the Skywalker residence . Luke found them , and immediately deduced that Lumiya had deliberately placed the boots where he would be sure to find them . Because of this , it was decided that Mara should find and confront Lumiya , while Luke himself monitored Jacen ' s actions . Mara Jade Skywalker immediately set out in search for the Sith Lady Lumiya , following a trail through the Force that pointed in the direction of Hesperidium , a resort - moon in the Coruscant star system . She immediately felt Lumiya ' s dark Force aura , and ignited her lightsaber as she began searching the surrounding hotel area for her quarry . Instead of finding Lumiya , however , Skywalker encountered the Sith ' s ship as she rounded the corner , one which resembled a large , disembodied eye . Communicating through the Force , the Sith ship beckoned Skywalker to enter ; an invitation which she cautiously accepted , fully expecting to find her quarry inside . She entered the empty vessel , had a brief discussion with the Meditation Sphere , and placed a tracking device inside before Lumiya herself finally appeared outside between a few parked ships . The two women silently acknowledged each other , and engaged in intense combat . The duel . Skywalker leaped at Lumiya with her lightsaber drawn , managing to slice off a corner of the Sith ' s headdress . In turn , Lumiya quickly whirled her lightwhip in Skywalker ' s direction , but missed her target after being Force - pushed away by the Jedi Master . Skywalker evaded as Lumiya lashed her whip again , this time just barely missing Skywalker ' s head . As Lumiya raised her arm for another strike , Skywalker shot her in the shoulder with her blaster , hitting one of Lumiya ' s cybernetics , but with little effect . Skywalker then quickly lunged at Lumiya ' s durasteel legs , the impact of which filled her mouth with blood , while at the same time toppling Lumiya . She then head - butted her cybernetic jaw causing more pain to herself . In a surprise tactic , Mara turned off her lightsaber , only to reignite it in Lumiya ' s chest . Ship then intervened , and Mara felt a metal coil wrap around her neck and throw her backwards . Mara hit the ground , looking up in time to see Lumiya ' s boots fly past her face . She then looked up to see the Sith Meditation Sphere fly away , with Lumiya safely inside . Aftermath . As the Jedi Council were discussing what action should be taken about the recent coup and the Mandalorian alliance with the Verpine , Mara entered the chamber still bearing her gruesome battle wounds . After assuring everyone she was fine , she informed them of Lumiya ' s new ship and that she would be ready for the next time she fought the Dark Lady of the Sith . Ben Skywalker later learned from the Ship that it intervened because its purpose was to train apprentices to fight . It would let the two fight but not let either one be killed . However , both combatants died not long after the duel . Soon after , Jacen Solo killed Mara on Kavan , and Luke Skywalker killed Lumiya on Terephon .
