Obi-Wan was in the seat of the tie fighter he had stolen. He was out in space until he returned to the fire planet known as Mustafar where it had all begun. He landed it on the pavement on the planet towards where Vader's fortress was.
Obi-Wan looks to the sky, imagining himself there ten years ago, the place where he had lost his friend, his brother, now he was here. It was either so he could die, or Anakin would die this time. Obi-Wan deeply inside felt the conflict, remembering the brotherhood they had up until his friend killed everyone at the temple including children. He recalled all the suffering that has happened since, thinking about Reva, and what she had gone through because of Anakin's deeds. So many lives lost because of him, now Obi-Wan has to do what needs to be done. He started to close his eyes, meditating in the seat, as he began to reach for his Master.
"Qui-Gon, he is coming, I don't know if I could go through with it this time, but he has caused so much pain I have to put him down, the boy you found is gone, replaced by something worse"
"There is always a way old friend" Qui-Gon's voice began to speak to him back"
"I am afraid not Master, he killed so many people. So many suffered while I stood in hiding, but this time I will correct my mistake. He has to die"
"Do you truly believe in my old Padawan?"
Obi-Wan looked to the ground, feeling nothing, but helplessness, then he looked up at the voice of his Master, "I wish there was another way. Forgive me Master, you are against this, but I most finish what I started.
"Very well, do what you need to, but know if you do this, you may never find peace, good luck Obi-Wan" the voice of Qui-Gon Jinn faded, leaving only Kenobi.
Obi-Wan sensed an incoming presence. Darth Vader was here.
Vader stepped out of his tie fighter, his boots stepping on the hot surface. He then looked ahead at the one that was stolen. That is when he felt it, his Master was here. Vader turned, walking towards the direction where the darkside was telling him. His anger continued to boil, waiting for the past ten years for this day. He used the force to push the stolen fighter in the lava incase he tried to make an escape.
Obi-Wan was waiting, a mile away, seeing Vader ahead, he had heard the lava splash, seeing his tie fighter fall in, which means he was stuck here unless he killed Vader.
Darth Vader paused, staring at his former Jedi Master. They were right behind his castle, he stared at it, then he said, "Have you come to save me Obi-Wan, or Destroy me?"
"I will do what I started years ago" Obi-Wan said, igniting his sapphire lightsaber, starting to get in his form three stance with no more words to say.
Vader grabbed his own lightsaber, "Then you will die, old friend" his crimson blade activated his crimson lightsaber.
The two galred at each other for at least a whole minute before Vader lunged at him, letting out a battle cry. The blades crossed each other. The weapons had kept hitting each other. Vader swung what would have cut Kenobis waist if Obi-Wan hadn't stepped back. Obi-Wan used his weapon to strike at Vader, but the dark lord perryed with his own saber. The Sith then used his strength to use his lightsaber, but Obi-Wan using form three was able to counter the attacks. He rolled away then tricked, but Vader blocked it, both their emotions fueling.
Obi-Wan used the force to push Vader back, but his mechanical legs stopped him from falling back. He spun his lightsaber in his hand for a second before using the force to leap forward. Vader blocked it, but Obi-Wan was able to hit a shoulder, causing him to stumble. Vader breathed, glaring at Obi-Wan, but holding his lightsaber in a defense.
"Impressive, glad you still retain your strength, but you underestimate the dark sides powers"
Vader used the force to levitate boulders in the air. He started throwing the small ones at Obi-Wan who cut them down with his lightsaber before getting striked on the shoulder. Vader kept sending it at him. Obi-Wan tried to dodge, but each one would keep on hitting him until he fell down the hill towards the lava bank.
Obi-Wan struggled to get up. He looked weaker, as Vader stepped down the hill. The boulders knocked the lightsaber out of his hand, and a distance away from him. Obi-Wan tried to use the force to reach out, but Vader already stood in his way, his crimson lightsaber activated, "This is the end my Master" Vader told him.
Obi-Wan knew this, it was the end for him. He closed his eyes in defeat, that is when he heard a familiar voice reach out to him.
"Obi-Wan, don't give up. The galaxy needs you, the boy needs you"
The voice of his Master Qui-Gon was right. If he died then Luke would be found, and the galaxy would have lost its last hope.
Obi-Wan quickly rolled under Vaders strike that would have decapitated him. He then would grab his lightsaber back by using the force, and lock blades with the dark lord. He fought fiercely, cutting though Vader's control panel attached to the chest of his suit. The dark lord struggled to breath, as he tried to fight back. Obi-Wan then delivered a slash towards Vaders knee. He bent down, feeling the cybernetics in his left leg failing. Vader struggled to breath, still determined, but Obi-Wan kept going on the offense, eventually making Vader's saber lower to the ground, then aiming the sapphire blade towards his head, removing the helmet.
Obi-Wan was about to deliver the killing blow until he stopped when he saw the hatred in his eyes by his former apprentice. Kenobi lowered his blade, lost for words, just staring at the man who he called friend.
"Anakin?"
"Anakin is dead, I am all that remains" Vader told Obi-Wan speaking in his weak voice, weezing air.
Obi-Wan was just shocked, not sure what to do, the once blue eyes of his Padawan was now replaced with an orange hate that belonged to a Sith. If he killed him then the twins would be safe, but he couldn't do it. Obi-Wan had his lightsaber ready, but his arm was shaking. Before he could make a move, a wave of stormtroopers came out from Vader's castle. They all had their blasters pointed at him. Obi-Wan quickly blocked the blaster bolts before using the force to speed himself off, running towards Vader's tie fighter.
Vader felt rage, he screamed Obi-Wans name. When a stormtrooper came to check on him, he snapped his neck before limping towards the hill. It was already to late though. Obi-Wan took off using his tie fighter. With a rage, Vader used the force to push the troopers into the lava before walking away.
Obi-Wan was already in space, on route towards getting out of there. He leaned back, thinking about the fight they had. He wondered if he was actually going to kill his old friend, but he had to accept the facts, Anakin Skywalker was dead, and he was alone once again.
