"And this fellow here is an old friend," the older doctor told the trainee, unlocking the door.
"Are you sure we should go in?" the younger one asked nervously as the door creaked open. "I thought 'maximum security' meant—"
The older doctor laughed.
"Don't worry. He can hardly move anyway." He called into the room. "Light's coming on, Sleeping Beauty."
Bright light flooded the room as he flicked on the switch, leading the way inside. Their boots swished on the soft carpet. There was a quiet groan from the corner, where a man was curled. His white clothes and hair blended in with the white walls so cleanly that he almost disappeared. The only think that stood out was his skin, which was a rich shade of golden-brown.
"Turn it off."
His voice was low and very controlled, as smooth as silk and as dark as midnight. It was almost enchanting in its quality, but the doctor was experienced.
"Sorry," he said, not sounding sorry at all. "Just showing a new one around."
The trainee felt like a bird trapped in the gaze of a snake as the man's eyes, narrowed to block out the light, fixed on him. Twin slits of amber scrutinized him, terrifying in their intensity. The older doctor's hand landed hard on his shoulder, shaking him free.
"This fellow doesn't have a name," he said. "We just made one up… we call him 'Xemnas.' He's in here because he thought it might be fun to strangle anyone within a twenty foot radius." He laughed as the young doctor backed away. "Don't worry, that's what the drugs are for. He can't do anything but talk to himself."
"About what?" the younger doctor asked.
"Darkness," the elder said, and the man in the corner twitched. "See? He's obsessed. Anyway, we keep him on sedatives and keep the lights off. Of course, once or twice he's shaken them off. We've only lost a few doctors, though."
"What if the drugs wear off while someone's in here?" the trainee asked, swallowing hard. As if on cue, the man wrenched himself over, making an awkward sort of lunge in their direction. He didn't get far, although his eyes blazed fiercely. The older doctor chuckled unpleasantly.
"That's what the straightjacket is for."

A/N: A prompt very near and dear to me... my own personal nightmare. The lucky Nobody who got plucked out of the magical jacket pocket? The Superior, of course.
