The Master Doorkeeper stands in contemplation. Students come. Some students leave. Sorcerers leave. Wizards leave. Some wizards return. The door opens. The door closes. The door opens again. All call him "Doorkeeper." Some call his True Name. He guards the door. He opens the door. He keeps out those who want in for the wrong reasons, and he keeps in those who haven't learned enough. Scrying shows nothing. Research discovers nothing. Guessing is impossible. Spying can't see him, threatening won't move him. Courteous and smiling, he stands contemplating. He, alone of all the Masters, teaches the human Art of asking.
