"A theory, which I will submit to you, my little test subject." He clears his throat. "Remember anything I told you about the Control? That little Sith toy that I'm after? You see, Darth Luunis had tooled it to smash into his victims' minds and take over. It affects the mind. But it also corrupts it, just as the Dark Side of the Force does. After awhile he no longer needed to break into his victims' minds. It became an addiction, having the Control there. Luunis himself felt it, no doubt. It was comforting having the Sith Lord dictate thoughts, no matter how vicious or cruel...
"So my point there is that it became a covetous item that affected and corrupted the minds of individuals that came into close contact with it.
"My other point is that the Dark Side is... strange. As I said, the Control corrupted. It sapped Luunis' victims of their will to resist... but I am guessing that what is really did was absorbed their life essence, almost thrived off of its use under the Sith Lord. It wanted minds to meld to its will.
"It must be starving; few have used it since the days of Darth Luunis. You could say it almost wants to be found... which is why you saw Kyle. It appealed to the thing you want most right now, and right now you want to murder that damnable smugger and be done with this assignment. And then the Control lured you here, to this wall, where we are standing."
