Pacing, around and around in circles, Darth Vader was waiting news. The news of the next phase of his experiment to make his army more useful.

His cloak moved with him, as almost as if it were part of him. His tall, broad structure towered over many troopers, another reason why they feared  him. His lava eyes darted around the room, catching the eyes of all who walked past him. His latest scar - a gift from a now dead Padawan, slithered across his face. 

He paused as a door slid open behind him. He turned to see his personal surgeon standing in the door way. "Well?"

"My Lord," began the surgeon," The subject is prepped for the chip to be inserted.

"This is a risky procedure, My Lord. I suggest that we use the keyhole method rather than fully opening the skull to access the brain."

"Have I given you orders to use the  keyhole method?" snarled Vader. "Did I?"

"N-N-No, My Lord." The surgeon. "I will follow Phase 4 to your orders, My Lord."

"Very good," Darth Vader flashed him a small smile. "Now, before you begin, I wish to see the subject."

"As you wish My Lord." Darth Vader walked past the surgeon, entering the door way. The surgeon followed the Sith, trying to avoid eye contact.

"I trust you to carry out this procedure with no problems," Vader looked at the surgeon, who was now sat behind a desk, looking at scans of the subject's brain. "Phase 4 is to be the breaking point of this experiment, not the failure, which means that all of the other subjects will have to be terminated, or sent back to Kamino for reprogramming, depending on their mental and physical state."

"I will not fail you, my Lord." The surgeon looked up from the computer, nodding in respect. "I want this experiment to succeed, as well."

"That's a very good answer." Vader replied. "Now, where is the subject?"

"In the theatre." reported the surgeon, getting out his seat. He took a deep breath, and lead Vader through another door.

Heavily sedated and unconscious, was a man strapped down and wired up to an operating table. His head was bald, but as Darth Vader looked closely, he could see a faint hint of stubble. The man's head was turned on his left side. As Vader looked at the neck, he could see a small blue tattoo, of someone's markings. The blue didn't match his old legion's colour of blue but somebody else's. What did those markings remind him of? 

Satisfied with what he saw, Vader looked back at the surgeon. "I expect this procedure to complete by the next Corusaunt rotation."

"As you wish, Lord Vader." the surgeon bowed his head, and watched as the most feared Sith Lord stormed out of the  procedure room, leaving him to complete his job, with his life on the line.
