Duel at the Lake of Apparitions The duel at the Lake of Apparitions was a battle between Grand Master Luke Skywalker , Dark Lord of the Sith Darth Krayt , and the dark side entity Abeloth that occurred on Abeloth ' s planet in the year 44 ABY . Luke Skywalker and his niece , newly appointed Jedi Master Jaina Solo , had followed Abeloth to the Maw , where she had taken Skywalker ' s son Ben and the Sith apprentice Vestara Khai in the meditation sphere Ship . Abeloth was attempting to recreate the Family of the Ones , who had died on the planet Mortis around 21 BBY , by making Ben and Vestara drink from the Font of Power and bathe in the Pool of Knowledge . When Luke and Jaina ' s ship , the " Rude Awakening " , was attacked by Ship , Luke entered the realm of beyond shadows to seek help from the spirit of his wife , Mara Jade Skywalker . There , he encountered the Dark Man of his visions from four years earlier , who joined him in battle against Abeloth . Prelude . When the " Rude Awakening " was attacked by the Sith Meditation Sphere Ship , Luke Skywalker strapped himself into a medbay and traveled beyond shadows . He arrived at the Lake of Apparitions , where he traveled across the Lake until he found the spirit of his wife , Mara Jade . He asked Mara for anything she could tell him about how to defeat Abeloth , but she had nothing — and then the spirit of Jacen Solo arrived as well . Jacen was initially disappointed in Luke for blaming Abeloth ’ s escape on his nephew , but his scorn vanished when Luke explained that Jacen ’ s attempt to change what he saw in the Pool of Knowledge had resulted in the entity ' s freedom . Mara and Jacen were still unable to help him , but then the Dark Man arrived . The newcomer was in fact the Dark Lord of the Sith Darth Krayt , leader of the One Sith . Without revealing his true identity , he informed Luke that he was a Sith , and that he was there to help Skywalker defeat Abeloth . The duel . At that moment , Abeloth arrived out of the Mists of Forgetfulness . The Grand Master attempted to reach for his lightsaber , but as he was beyond shadows , he did not have one . Luke then attempted to blast Abeloth with Force energy , but she had already unleashed a barrage of Force lightning that passed through Krayt and slammed into the Jedi . Once he had recovered , the two began to pummel Abeloth with blasts of Force energy until she began to fall into the Lake itself . During the battle , Luke ’ s sense of time was warped , so what seemed like a lifetime could have been a blink of an eye . As Abeloth was about to fall into the water , Luke ran to her side and began to attack her physically ( or what passed for physical beyond shadows – the combat was between their Force essence s , and as such there were no physical injuries ) . Luke began to gain the upper hand over Abeloth , and the two began to grapple as Abeloth ’ s tentacles lashed Luke ’ s face . One of her tentacles hit Luke in the right eye , blinding him in that eye . Then Krayt joined the fight , jabbing his fingers in Abeloth ’ s stomach and causing a black spray to erupt . As the three tumbled across the surface of the Lake , Abeloth attempted to Force - blast Krayt off of her , but her efforts were in vain . Suddenly Krayt turned on Luke and Abeloth , using a Force draining technique to steal both of their powers . In response , Luke bashed the Sith ’ s knee and threw him off the other two , dropping him to the surface of the Lake . Luke threatened to release Abeloth if Krayt did not stop , and Krayt consented despite his words otherwise . Luke held fast to Abeloth as Krayt continued to drain her for what seemed like days , but it suddenly felt like seconds as the Sith began to scream in anguish . Force energy , black and shiny , began to seep from Krayt ’ s wounds across the Lake in a boiling , oily slick that caused the water to steam and hiss . Luke realized that Krayt had in fact not betrayed Luke – the effort of holding Abeloth down was taking as much from Luke as the draining was from Krayt . Krayt tried to use the Force to pull his hand back to him , but Luke realized that she had only fled because she was actually dying – and that her only option now was to attack . She teleported back to the duo , slamming a ball of tentacles deep in Krayt ’ s chest and then Luke ’ s as well when he tried to help . Despite her attack , Luke continued to press the offensive , grappling with her mercilessly until his elbow simply pushed through Abeloth ' s head . At that very moment , Saba Sebatyne succeeded in killing Abeloth ’ s avatar that was inhabiting the Jedi Temple ' s computer core . Simultaneously , near the Font of Power , Ben killed Abeloth ’ s avatar High Lord Korelei with a shikkar . With the death of her last two bodies and the destruction of her Force essence , Abeloth died . Her body fell away pulling the tentacles with her and leaving Krayt and Luke holding pieces of her essence . The two collapsed , the tentacles having left gaping holes in their chests . Luke fell unconscious as he began to scream , causing his physical body back on the " Rude Awakening " to scream as well . Aftermath . When Luke and Krayt awoke , Abeloth ' s body was starting to sink into the Lake of Apparitions as it shrank . With the death of Abeloth , the Family of the Ones finally met its end – a process begun almost 65 years ago , with the death of the Father , the Son , and the Daughter . Luke believed that by defeating Abeloth , he had prevented the rise of the Sith forever , and that he had restored the course of the Current of the Force , as the Thuruht s believed the Ones were meant to do . But Jacen informed him that he had in fact " not " prevented the Sith ' s rise – he had simply prevented Jacen ’ s vision from coming true . Jacen also told Luke what he really saw in the Pool of Knowledge — the vision that had ultimately caused him to turn to the dark side and become Darth Caedus : he had seen the Dark Man on the Throne of Balance , but what he had tried to prevent was his daughter Allana standing next to Krayt on the Throne . In addition , although Abeloth had died , the New Jedi Order anticipated the possibility of Abeloth returning , so they dispatched Quest Knights to locate the Mortis monolith in order to retrieve the Dagger of Mortis , as a precautionary method in case she did return , as a means to kill her for good .
