Summary: What if Luke did go with Vader when he found out he was his father?

Chapter 1

Vader was having fun fighting his son. He would attack and Luke would block or parry. If only Obi-Wan and Yoda told Luke the truth about his father. Vader finally became bored of fighting and used his Force powers to throw different objects at him. Luke had enough skill to know how to use his lightsaber and some Force powers. He swung at the object that came from behind, and sliced it in half. Before he could turn around and slice another object in half, it hit him in the back. Luke sensed another attempt at catching him by surprise and jumped out of the way just in time. Unfortunately he was standing right in front of a window. Before Luke knew what happened, he went flying out the window. 'Why the hell did Vader choose Cloud City?' Luke thought as he hit the catwalk full force. All of the air was knocked out of him that he just laid there to catch his breath.

Vader watched as his son was sucked out the window. Before he went in search for him, he stretched out with his senses to make sure he was still alive. He was still alive 'thank the Sith.' Vader muttered and walked to were he sensed Luke in a lot of pain.

With Luke

Luke got up after a few minutes of laying there. He found an exit to get back inside. Right when he stepped into the doorway he sensed a great evil heading his way. He knew immediately who it was when he heard a snap-hiss indicating that a lightsaber was on. He looked down at his to make sure it wasn't his at first then with a snap-hiss he ignited his own blue blade. Luke raised up his blade to a defensive stance, waiting for Vader to attack.

With Vader

Vader walked for a while and finally found his son standing before him. Vader ignited his red blade with a snap-hiss and raised it up in one hand. Vader knew Luke heard him turn on his blade and turned on his own. As he advanced, Luke backed up out onto the catwalk he was just on. Vader attacked and Luke blocked. When there blades were together Vader said in an icy calm voice "Accept your defeat." In return Luke shook his head and pushed Vader back a bit. Luke stumbled on a step and fell. Vader came up to him and put his lightsaber to Luke's face.

"You are defeated." He said n his coldest voice. Without any answer Luke got up and fought back. Vader saw this and backed up and took one clean swipe and took off Luke's hand.

Luke let out a yell of agony as he clutched the stump of his hand, he fell to his knees. When he saw Vader approaching he started backing up. When he reached the end of the catwalk. He looked behind him and saw poles behind him. He crawled onto the poles holding on with his legs and his one hand.

"There is no escape. Don't make me destroy you. You do not yet realize your importance. You have only begun to discover you power. Join me and I will complete your training. With our combined strength, we can end this destructive conflict and bring order to the galaxy."

"I'll never join you!" Luke yelled

"If you only knew the power of the dark side. Obi-Wan never told you what happened to your father."

"Yes. He told me what I needed to know about you and him. How you guys were friends and then you betrayed him."

"No I didn't betray him. I am your father."
