Terry Pratchett - The Light Fantastic

The sun rose slowly, as if it wasnt sure it was worth all the effort.

Another Disc day dawned, but very gradually, and this is why.

When light encounters a strong magical field it loses ail sense of urgency. It slows right down. And on the Discworld the magic was embarrassingly strong, which meant that the soft yellow light of dawn flowed over the sleeping landscape like the caress of a gentle lover or, as some would have it, like golden syrup. It paused to fill up valleys. It piled up against mountain ranges. When it reached Cori Celesti, the ten mile spire of grey stone and green ice that marked the hub of the Disc and was the home of its gods, it built up in heaps until it finally crashed in great lazy tsunami as silent as velvet, across the dark landscape beyond.

It was a sight to be seen on no other world.

Of course, no other world was carried through the starry infinity on the backs of four giant elephants, who Aere themselves perched on the shell of a giant turtle. His nameor Her name, according to another school of thoughtwas Great ATuin; heor, as it might be, shewill not take a central role in what follows but it is vital to an understanding of the Disc that heor sheis there, down below the mines and sea ooze and fake fossil bones put there by a Creator with nothing better to do than upset archeologists and give them silly ideas.

Great ATuin the star turtle, shell frosted with frozen methane, pitted with meteor craters, and scoured with asteroidal dust. Great ATuin, with eyes like ancient seas and a brain the size of a continent through which thoughts moved like little glittering glaciers. Great ATuin of the great slow sad flippers and star-polished carapace, labouring through the galactic night under the weight of the Disc. As large as worlds. As old as Time. As patient as a brick.

Actually, the philosophers have got it all wrong. Great ATuin is in fact having a great time.

Great ATuin is the only creature in the entire universe that knows exactly where it is going.

Of course, philosophers have debated for years about where Great ATuin might be going, and have often said how worried they are that they might never find out.

Theyre due to find out in about two months. And then theyre really going to worry...

Something else that has long worried the more imaginative philosophers on the Disc is the question of Great ATuins sex, and quite a lot of time and trouble has been spent in trying to establish it once and for all.

In fact, as the great dark shape drifts past like an endless tortoiseshell hairbrush, the results of the latest effort are just coming into view.

Tumbling past, totally out of control, is the bronze shell of the Potent Voyager, a sort of neolithic spaceship built and pushed over the edge by the astronomer-priests of Krull, which is conveniently situated on the very rim of the world and proves, whatever people say, that there is such a thing as a free launch.

Inside the ship is Twoflower, the Discs first tourist. He had recently spent some months exploring it and is now rapidly leaving it for reasons that are rather complicated but have to do with an attempt to escape from Krull.

This attempt has been one thousand per cent successful.

But despite all the evidence that he may be the Discs last tourist as well, he is enjoying the view.

Plunging along some two miles above him is Rincewind the wizard, in what on the Disc passes for a spacesuit. Picture it as a diving suit designed by men who have never seen the sea. Six months ago he was a perfectly ordinary failed wizard. Then he met Twoflower, was employed at an outrageous salary as his guide, and has spent most of the intervening time being shot at, terrorised, chased and hanging from high places with no hope of salvation or, as is now the case, dropping from high places.

He isnt looking at the view because his past life keeps flashing in front of his eyes and getting in the way. He is learning why it is that when you put on a spacesuit it is vitally important not to forget the helmet.

A lot more could be included now to explain why these two are dropping out of the world, and why Twoflowers Luggage, last seen desperately trying to follow him on hundreds of little legs, is no ordinary suitcase, but such questions take time and could be more trouble than they are worth. For example, it is said that someone at a party once asked the famous philosopher Ly Tin Weedle Why are you here? and the reply took three years.

What is far more important is an event happening way overhead, far above ATuin, the elephants and the rapidly-expiring wizard. The very fabric of time and space is about to be put through the wringer.

The air was greasy with the distinctive feel of magic, and acrid with the smoke of candles made of a black wax whose precise origin a wise man wouldnt inquire about.

There was something very strange about this room deep in the cellars of Unseen University, the Discs premier college of magic. For one thing it seemed to have too many dimensions, not exactly visible, just hovering out of eyeshot. The walls were covered with occult symbols, and most of the floor was taken up by the Eightfold Seal of Stasis, generally agreed in magical circles to have all the stopping power of a well-aimed half brick.

The only furnishing in the room was a lectern dark wood, carved into the shape of a birdwell, to be frank, into the shape of a winged thing it is probably best not to examine too closelyand on the lectern, fastened to it by a heavy chain covered in padlocks, was a book.

A large, but not particularly impressive, book. Other books in the Universitys libraries had covers inlaid with rare jewels and fascinating wood, or bound with dragon skin. This one was just a rather tatty leather. It looked the sort of book described in library catalogues as slightly foxed, although it would be more honest to admit that it looked as though it had been badgered, wolved and possibly beared as well.

Metal clasps held it shut. They werent decorated, they were just very heavylike the chain, which didnt so much attach the book to the lectern as tether it.

They looked like the work of someone who had a pretty definite aim in mind, and who had spent most of his life making training harness for elephants.

The air thickened and swirled. The pages of the book began to crinkle in a quite horrible, deliberate way, and blue light spilled out from between them. The silence of the room crowded in like a fist, slowly being clenched.

Half a dozen wizards in their nightshirts were taking turns to peer in through the little grille in the door. No wizard could sleep with this sort of thing going onthe build-up of raw magic was rising through the university like a tide.

Right, said a voice. Whats going on? And why wasnt I summoned?

Galder Weatherwax, Supreme Grand Conjuror of the Order of the Silver Star, Lord Imperial of the Sacred Staff, Eighth Level Ipsissimus and 304th Chancellor of Unseen University, wasnt simply an impressive sight even in his red nightshirt with the hand-embroidered mystic runes, even in his long cap with the bobble on, even with the Wee Willie Winkie candlestick in his hand. He even managed to very nearly pull it off in fluffy pompom slippers as well.

Six frightened faces turned towards him.

Um, you were summoned, lord, said one of the under-wizards.

Thats why youre here, he added helpfully.

I mean why wasnt I summoned before? snapped Galder, pushing his way to the grille.

Um, before who, lord? said the wizard.

Galder glared at him, and ventured a quick glance through the grille.

The air in the room was now sparkling with tiny flashes as dust motes incinerated in the flow of raw magic. The Seal of Stasis was beginning to blister and curl up at the edges.
