Midnight laughed. "I think this will help you, then," she said, leading the way back to her bedroom. Inside, she opened a hidden recess in the wall, and opened the safe secured within, pulling out a small box.<br/><br/>"Your collar is designed for<em>much</em>more than simple control. In fact, it's quite illegal on at least... oh, three dozen worlds that I know of, and the rest probably haven;t outlawed it yet. Fortunately, this particular one is keyed to only work with you, which reduces it from death sentence to mere heavy fine, on all but three worlds, and I don't plan to visit those, anyway. Bunch of prudes."<br/><br/>She scowled for a moment, then shook her head. "What it does it it takes a constant reading of your brain, scanning and actually recording it onto a small chip, in the collar. It has to be worn for at least a day, first, in order to get a full read on you, and what it allows me to do is to replace it with chips from this box, here that... alter your mind. Some adjust your memories, planting new ones or eliminating old ones; some might adjust your personality, making you utterly meek and submissive... or dedicated to nothing but trying to get away. I chose a few packages that I particularly liked. There's no harm; it doesn't truly<em>alter</em>your memories, just... makes certain ones less likely to come to the surface and influence your thoughts, or providing alternates in their place."<br/><br/>"For instance," she said, picking out one chip from the box. "This one's almost a 'factory reset'. It's keyed to a point during your training, suppressing memories you'd acquired after that point, functionally making it so that, every time I activate it, you revert to being as you were supposed to be when delivered to me. Once it's removed, all your memories return to normal, the original chip ensuring that. This one," she said, putting the first away, and pulling out a new one. "Alters your memories, and makes you believe that you are a virgin elven princess, kidnapped and sold to me on the slave markets, and that the loss of your virginity means the loss of your right to be queen. I then get to torment you and play with you, holding it over your head as a threat," she said, giggling. "There's a few others, and I ahve a suite of them at home, that I can make, if there's a particular idea you like."
