Its head passed in front of her and she looked directly into an eye big enough to float all the fleets in the world. She had heard it said that if you could look far enough into the direction that Great A'Tuin was staring, you would see the end of the universe. Maybe it was just the set of its beak, but Great A'Tuin looked vaguely hopeful, even optimistic. Perhaps the end of everything wasn't as bad as all that.
Dreamlike, she reached out and tried to Borrow the biggest mind in the universe.
She stopped herself just in time, like a child with a toy toboggan who expected a little gentle slope and suddenly looks out of the magnificent mountains, snow-covered, stretching into the icefields of infinity. No one would ever Borrow that mind, it would be like trying to drink all the sea. The thoughts that moved through it were as big and as slow as glaciers.
Beyond the Disc were the stars, and there was something wrong with them. They were swirling like snowflakes. Every now and again they would settle down and look as immobile as they always did, and then they'd suddenly take it into their heads to dance.
Real stars shouldn't do that, Esk decided. Which meant she wasn't looking at real stars. Which meant she wasn't exactly in a real place. But a chittering close at hand reminded her that she could almost certainly really die if she once lost track of those noises. She turned and pursued the sounds through the stellar snowstorm.
And the stars jumped, and settled, jumped, and settled ....
As she swooped upward Esk tried to concentrate on everyday things, because if she let her mind dwell on precisely what it was she was following then she knew she would turn back, and she wasn't sure she knew the way. She tried to remember the eighteen herbs that cured ear-ache, which kept her occupied for a while because she could never recall the last four.
A star swooped past, and then was violently jerked away; it was about twenty feet across.
When she ran out of herbs she started on the diseases of goats, which took quite a long time because goats can catch a lot of things that cows can catch plus a lot of things plus that sheep plus catch plus a complete range of horrible ailments of their very own. When she had finished listing wooden udder, ear wilt and the octarine garget she tried to recall the complex code of dots and lines that they used to cut in the trees around Bad Ass, so that lost villagers could find their way home on snowy nights.
She was only as far as dot dot dot dash dot dash (Hub-byTurnwise, one mile from the village) when the universe around her vanished with a faint pop. She fell forward, hit something hard and gritty and rolled to a halt.
The grittiness was sand. Fine, dry, cold sand. You could tell that even if you dug down several feet it would be just as cold and just as dry.
Esk lay with her face in it for a moment, summoning the courage to look up. She could just see, a few feet away from her, the hem of someone's dress: Something's dress, she corrected herself. Unless it was a wing. It could be a wing, a particularly tatty and leathery one.
Her eyes followed it up until she found a face, higher than a house, outlined against the starry sky. Its owner was obviously trying to look nightmarish, but had tried too hard. The basic appearance was that of a chicken that had been dead for about two months, but the unpleasant effect was rather spoiled by warthog tusks, moth antennae, wolf ears and a unicorn spike. The whole thing had a selfassembled look, as if the owner had heard about anatomy but couldn't quite get to grips with the idea.
It was staring, but not at her. Something behind her occupied all its interest. Esk turned her head very slowly.
Simon was sitting cross-legged in the centre of a circle of Things. There were hundreds of them, as still and silent as statues, watching him with reptilian patience.
There was something small and angular held in his cupped hands. It gave off a fuzzy blue light that made his face look strange.
Other shapes lay on the ground beside him, each in its little soft glow. They were the regular sort of shapes that Granny dismissed airily as jommetry-cubes, many-sided diamonds, cones, even a globe. Each one was transparent and inside was ....
Esk edged closer. No one was taking any notice of her.
Inside a crystal sphere that had been tossed aside on to the sand floated a blue-green ball, crisscrossed with tiny white cloud patterns and what could almost have been continents if anyone was silly enough to try to live on a ball. It might have been a sort of model, except something about its glow told Esk that it was quite real and probably very big and not - in every sense - totally inside the sphere.
She put it down very gently and sidled over to a ten-sided block in which floated a much more acceptable world. It was properly discshaped, but instead of the Rimfall there was a wall of ice and instead of the Hub there was a gigantic tree, so big that its roots merged into mountain ranges.
A prism beside it held another slowly-turning disc, surrounded by little stars. But there were no ice walls around this one, just a red-gold thread that turned out on closer inspection to be a snake - a snake big enough to encircle a world. For reasons best known to itself it was biting its own tail.
Esk turned the prism over and over curiously, noticing how the little disc inside stayed resolutely upright.
Simon giggled softly. Esk replaced the snake-disc and peered carefully over his shoulder.
He was holding a small glass pyramid. There were stars in it, and occasionally he would give it a little shake so that the stars swirled up like snow in the wind, and then settled back in their places. Then he would giggle.
And beyond the stars ....
It was the Discworld. A Great A'Tuin no bigger than a small saucer toiled along under a world that looked like the work of an obsessive jeweller.
Jiggle, swirl. Jiggle, swirl, giggle. There were already hairline cracks in the glass.
Esk looked at Simon's blank eyes and then up into the hungry faces of the nearest Things, and then she reached across and pulled the pyramid out of his hands and turned and ran.
The Things didn't stir as she scurried towards them, bent almost double, with the pyramid clasped tightly to her chest. But suddenly her feet were no longer running over the sand and she was being lifted into the frigid air, and a Thing with a face like a drowned rabbit turned slowly towards her and extended a talon.
You're not really here, Esk told herself. It's only a sort of dream, what Granny calls an annaloggy. You can't really be hurt, it's all imagination. There's absolutely no harm that can come to you, it's all really inside your mind.
