Star Wars: 10 Reasons Duel Of The Fates Would've Been Way Better Than Rise Of Skywalker
5. Kylo Ren Faces Off With Luke And Darth Vader
After discovering the Holocron (no thanks to Force Ghost Luke) on Mustafar, Kylo Ren travels in search of an ancient well of power in the Sith temple called Mortis. Honestly, Mustafar, Exegol, Mortis... did the Sith ever stop and listen to the names of their home planets and ask themselves if they were in fact the bad guys?
(Technically Mortis isn't a Sith homeworld, and is instead the location of the physical manifestations of the Force, but still.)
On Mortis, Ren finally meets the notorious Sith lord known as Tor Valum who agrees to teach him about the depths of the dark side. His training not only teaches him the ability to suck the life force out of living things to gain strength but it brings him to the very edge of immortality, making him the strongest Sith to have ever existed.
Similar to Luke's training on Dagobah, Kylo Ren is drawn to a cave with strong auras of the dark side. In the cave, he confronts his greatest fear - Darth Vader, and the two engage in an epic battle.
