Duel on Jwlio The Duel on Jwlio was a lightsaber duel that occurred in the year 35 ABY at the onset of the Dark Nest Crisis . On the planet Jwlio , Jedi Master Saba Sebatyne confronted the Dark Jedi Welk , and in the depths far beneath the surface of that world , the Barabel Jedi engaged the Night Herald of the Gorog in vicious lightsaber combat . Prelude . After Jedi Knight Jaina Solo disregarded her orders during the attempted rescue of Jedi Knight Lowbacca , Jedi Master Saba Sebatyne traveled deep within the caverns of the moon Jwlio to clear her mind while hunting . During her hunt , Master Sebatyne encountered a precise cut into the center of a stone ; indicating a lightsaber had been used . Feeling that her prey had become more interesting than she had first suspected , Saba examined the cleft it had cut ; within were several empty cells . While she examined the empty cells , Master Sebatyne sensed bitterness nearby and her danger sense grew . The duel . The hunt is on . Sebatyne surprised her attacker by spinning around quickly , taking his feet from under him with a quick swipe of her Barabel tail , eliminating his chance to kill the her while her back was turned . Completing her spin , Sebatyne ignited her lightsaber as the crimson colored blade of her opponent ignited in time to block her attack . A Force Wave then blasted her across the cavern , slamming her head hard into the stone wall , the concussion of which began to blur her vision . Additionally , Sebatyne could not sense her opponent within the Force . Thus , while she examined her opponent with compromised vision , he lifted himself off the ground , and arrogantly waited for the Jedi Master to ask his name , or composed himself to continue the duel . Sebatyne leaped at her opponent and attacked with a vicious overhand slash , forcing him back several steps to block her blade . The Barabel brought her knee around to slam into the chest of her attacker , but was met with a harder surface than expected , leaving her to feel as if she had struck a statue . The attacker capitalized on the Barabel ' s shock and slipped his palm - heel under her guard , hitting her under the chin , and sending her staggering backwards . The Jedi Master then kicked a fist - sized stone off the floor and used the Force to hurl it at her opponents head , before following through with a cut attack to his knees . The mysterious attacker pivoted out of the way of the Force - hurled stone , before meeting the Barabel ' s blade , and sweeping it up into a disarming counter - arc . At the top of the maneuver , Sebatyne released her grip on her weapon and raked her claws down in a one - two slash ; the first strike opening up her opponent ' s face from temple to jaw , the second completely severing his eye . The attacker whirled away silently , yet screamed his agony into the Force , landing a stop kick into the Jedi Master ' s belly . Saba went with the attack , rolling into a quick back - flip and lost a section of her tail to her attackers blade . Herald of the Gorog . Knowing better than to allow the Barabel a chance to recover , the attacker unleashed a barrage of Force lightning at her , catching her full in the chest and bringing her to her knees in agony . As her attacker limped forward , Sebatyne saw him clearly for the first time ; it was the Dark Jedi , Welk . Stopping a meter and a half away from the Barabel , Welk brought his blade down in a decapitating strike ; however , Saba let loose a Force shove that sent the Dark Jedi tumbling backwards . As Welk staggered backwards his lightsaber scraped Sebatyne ' s skull , though she fought past the blinding pain to leap at him ; slamming into his chest and biting his throat . She had lost much strength due to her two head injuries and failed to sink her fangs deep enough into Welk ' s throat . In retaliation , Welk slammed Sebatyne backwards with the Force , but she recalled her lightsaber to her grasp as she soared towards the cavern wall . She fought off unconsciousness as she landed , she leapt at her attacker . Welk leveled another blast of lightning at the Jedi Master , however , she absorbed the barrage with her lightsaber , before pivoting past the sizzling arcs to rush her opponent . Welk brought his blade to a middle guard , while Master Sebatyne attacked high . The Dark Jedi blocked the Barabel ' s attack ; her reflexes fading . However , Welk was forced to retreat another step , while Saba launched a spinning attack , bringing her blade around in a shoulder slash and simultaneously swiped her bloodied tail at his legs . Due to her fading reflexes , Welk successfully blocked the shoulder slash and jumped the tail swipe ; however Saba brought her trailing foot around . Her foot taking the Dark Jedi ' s feet out from under him , Sebatyne executed a second spin that severed his Killik - arm , before adding a neck wound to his growing toll of injuries . However , Saba ' s compromised vision cost her as Welk sent a rock towards her ; hitting her in her head wound . This damaged the Barabel ' s sight further ; Welk took this advantage to retreat , blood gushing from his neck wound . Despite her opponent retreating , Saba sensed more danger than before . Dark - Nest Killik assassins attacked the Barabel , injecting poison into her . While Saba defeated the Killik ' s they exploded upon contact with her lightsaber blade , damaging her hand . Though Saba wished to pursue Welk , she realized that the Killik ' s had come from the empty cells she had encountered earlier ; however , one appeared to be missing and she feared it would attack the " Jade Shadow " . Aftermath . A Killik did indeed stow aboard the " Jade Shadow " , befriending the young Ben Skywalker in an attempt to undermine his relationship with his mother , Mara Jade Skywalker . Jade Skywalker , would later battle the assassin bug , knocking it unconscious to allow Jedi Master Cilghal to analyze it . Both Saba and Welk recovered from their injuries ; Welk would later be killed in a duel with Luke Skywalker , while Saba would continue to take part in the Dark Nest Crisis and ultimately survive the war .
