Darth Revan waited. The lights above him blinked and sparked out of the air. There were Sith in the Star Forge. He didn't see them, but had expected them now for years. His warnings to Padawan Shan were not listened to and it was too late. Far too late for now, anyway.
Revan was a Jedi for fourteen years. When he was young he watched the spaceships and he said to Carth "I want to be on the ships Carthy"
Carth said "No! You will BE KILL BY SITH!"
There was a time when he believed him. Then as he got oldered he stopped. But now in the control room of the Star Forge he knew there were Sith.
"This is Shan" the radio crackered. "You must fight the Sith!"
So Revan gotted his palsma sword and blew up the wall.
"HE GOING TO KILL US" said the Sith
"I will shoot at him" said Darth Malak and he unleashed a whole bunch of Star Forge droids. Revan Force'd at him and tried to blew him up. But then the ceiling fell and they were trapped and not able to kill.
"No! I must kill the Sith!" he said.
The radio said "No, Revan. You are the Sith."
And then Revan was the Dark Lord.
