The little white stub skittered and squeaked across the blackness to the accompaniment of Simon’s voice. Even allowing for the stutter, he was not a very good speaker. He dropped notes. He corrected himself. He ummed and ahhed. And as far as Esk was concerned he wasn’t saying anything very much. Phrases filtered down to her hiding place. “Basic fabric of the universe” was one, and she didn’t understand what that was, unless he meant denim, or maybe flannelette. “Mutability of the possibility matrix” she couldn’t guess at all.
Sometimes he seemed to be saying that nothing existed unless people thought it did, and the world was really only there at all because people kept on imagining it. But then he seemed to be saying that there was lots of worlds, all nearly the same and all sort of occupying the same place but all separated by the thickness of a shadow, so that everything that ever could happen would have somewhere to happen in.
(Esk could get to grips with this. She had half-suspected it ever since she cleaned out the senior wizards’ lavatory, or ratherwhile the staff got on with the job while Esk examined the urinals and, with the assistance of some half-remembered details of her brothers in the tin bath in front of the fire at home, formulated her unofficial General Theory of comparative anatomy. The senior wizards’ lavatory was a magical place, with real running water and interesting tiles and, most importantly, two big silver mirrors fixed to opposite walls so that someone looking into one could see themselves repeated again and again until the image was too small to see. It was Esk’s first introduction to the idea of infinity. More to the point, she had a suspicion that one of the mirror Esks, right on the edge of sight, was waving at her.)
There was something disturbing about the phrases Simon used. Half the time he seemed to be saying that the world was about as real as a soap bubble, or a dream.
The chalk shrieked its way across the board behind him. Sometimes Simon had to stop and explain symbols to the wizards, who seemed to Esk to be getting excited at some very silly sentences. Then the chalk would start again, curving across the darkness like a comet, trailing its dust behind it.
The light was fading out of the sky outside. As the room grew more gloomy the chalked words glowed and the blackboard appeared to Esk to be not so much dark as simply not there at all, but just a square hole cut out of the world.
Simon talked on, about the world being made up of tiny things whose presence could only be determined by the fact that they were not there, little spinning balls of nothingness that magic could shunt together to make stars and butterflies and diamonds. Everything was made up of emptiness.
The funny thing was, he seemed to find this fascinating.
Esk was only aware that the walls of the room grew as thin and insubstantial as smoke, as if the emptiness in them was expanding to swallow whatever it was that defined them as walls, and instead there was nothing but the familiar cold, empty, glittering plain with its distant worn hills, and the creatures that stood as still as statues, looking down. There were a lot more of them now. They seemed for all the world to be clustering like moths around a light.
One important difference was that a moth’s face, even close up, was as friendly as a bunny rabbit’s compared to the things watching Simon.
Then a servant came in to light the lamps and the creatures vanished, turning into perfectly harmless shadows that lurked in the corners of the room.
At some time in the recent past someone had decided to brighten the ancient corridors of the University by painting them, having some vague notion that Learning Should Be Fun. It hadn’t worked. It’s a fact known throughout the universes that no matter how carefully the colours are chosen, institutional decor ends up as either vomit green, unmentionable brown, nicotine yellow or surgical appliance pink. By some little understood process of sympathetic resonance, corridors painted in those colours always smell slightly of boiled cabbage -- even if no cabbage is ever cooked in the vicinity.
Somewhere in the corridors a bell rang. Esk dropped lightly from her windowsill, grabbed the staff and started to sweep industriously as doors were flung open and the corridors filled with students. They streamed past her on two sides, like water around a rock. For a few minutes there was utter confusion. Then doors slammed, a few laggard feet pattered away in the distance, and Esk was by herself again.
Not for the first time, Esk wished that the staff could talk. The other servants were friendly enough, but you couldn’t talk to them. Not about magic, anyway.
