The broom whisked down the corridor raising a great cloud of dust which, if you looked hard at it, seemed somehow to be sucked back into the broomstick. If you looked even harder you'd see that the broom handle had strange markings on it, which were not so much carved as clinging and somehow changed shape as you watched.
But no one looked.
Esk sat at one of the high deep windows and stared out over the city. She was feeling angrier than usual, so the broom attacked the dust with unusual vigour. Spiders ran desperate eight-legged dashes for safety as ancestral cobwebs disappeared into the void. In the walls mice clung to each other, legs braced against the inside of their holes. Woodworm scrabbled in the ceiling beams as they were drawn, inexorably, backwards down their tunnels.
“'You can really clean up',” said Esk. “Huh!”
There were some good points, she had to admit. The food was simple but there was plenty of it, and she had a room to herself somewhere in the roof and it was quite luxurious because here she could lie in until five a. m., which to Granny's way of thinking was practically noon. The work certainly wasn't hard. She just started sweeping until the staff realised what was expected of it, and then she could amuse herself until it was finished. If anyone came the staff would immediately lean itself nonchalantly against a wall.
But she wasn't learning any wizardry. She could wander into empty classrooms and look at the diagrams chalked on the board, and on the floor too in the more advanced classes, but the shapes were meaningless. And unpleasant.
They reminded Esk of the pictures in Simon's book. They looked alive.
She gazed out across the rooftops of Ankh-Morpork and reasoned like this: writing was only the words that people said, squeezed between layers of paper until they were fossilized. Fossils were well-known on the Discworld, great spiralled shells and badly-constructed creatures that were left over from the time when the Creator hadn't really decided what He wanted to make and was, as it were, just idly messing around with the Pleistocene). And the words people said were just shadows of real things. But some things were too big to be really trapped in words, and even the words were too powerful to be completely tamed by writing.
So it followed that some writing was actually trying to become things. Esk's thoughts became confused things at this point, but she was certain that the really magic words were the ones that pulsed angrily, trying to escape and become real.
They didn't look very nice.
But then she remembered the previous day.
It had been rather odd. The University classrooms were designed on the funnel principle, with tiers of seats - polished by the bottoms of the Disc's greatest mages - looking precipitously down into a central area where there was a workbench, a couple of blackboards and enough floor space for a decent-sized instructional octogram. There was a lot of dead space under the tiers and Esk had found it a quite useful observation post, peering around between the apprentice wizards' pointy boots at the instructor. It was very restful, with the droning of the lecturers drifting over her as gently as the buzzing of the slightly zonked bees in Granny's special herb garden. There never seemed to be any practical magic, it always seemed to be just words. Wizards seemed to like words.
But yesterday had been different. Esk had been sitting in the dusty gloom, trying to do even some very simple magic, when she heard the door open and boots clump across the floor. That was surprising in itself. Esk knew the timetable, and the Second Year students who normally occupied this room were down for Beginners' Dematerialisation with Jeophal the Spry in the gym. (Students of magic had little use for physical exercise; the gym was a large room lined with lead and rowan wood, where neophytes could work out at High magic without seriously unbalancing the universe, although not always without seriously unbalancing themselves. Magic had no mercy on the ham-fisted. Some clumsy students were lucky enough to walk out, others were removed in bottles.)
Esk peeped between the slats. These weren't students, they were wizards. Quite high ones, to judge by their robes. And there was no mistaking the figure that climbed on to the lecturer's dais like a badlystrung puppet, bumping heavily into the lectern and absent-mindedly apologising to it. It was Simon. No one else had eyes like two raw eggs in warm water and a dose bright red from blowing. For Simon, the pollen count always went to infinity.
It occurred to Esk that, minus his general allergy to the whole of Creation and with a decent haircut and a few lessons in deportment, the boy could look quite handsome. It was an unusual thought, and she squirrelled it away for future consideration.
When the wizards had settled down, Simon began to talk. He read from notes, and every time he stuttered over a word the wizards, as one man, without being able to stop themselves, chorused it for him.
After a while a stick of chalk rose from the lectern and started to write on the blackboard behind him. Esk had picked up enough about wizard magic to know that this was an astounding achievement- Simon had been at the University for a couple of weeks, and most students hadn't mastered Light Levitation by the end of their second year.
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.
