largest turtle there has ever been, carrying on its carapace the four huge elephants that bore on their backs the vast, glittering waterfall-fringed circle of the Discworld, which exists either because of some impossible blip on the curve of probability or because the gods enjoy a joke as much as anyone.

Spring had come to Ankh-Morpork. It wasn’t immediately apparent, but there were signs that were obvious to the cognoscenti. For example, the scum on the River Ankh, that great wide slow waterway that served the double city as reservoir, sewer and frequent morgue, had turned a particularly iridescent green. The city’s drunken rooftops sprouted mattresses and bolsters as the winter bedding was put out to air in the weak sunshine, and in the depths of musty cellars the beams twisted and groaned when their dry sap responded to the ancient call of root and forest. Birds nested among the gutters and eaves of Unseen University, although it was noticeable that however great the pressure on the nesting sites they never, ever, made nests in the invitingly open mouths of the gargoyles that lined the rooftops, much to the gargoyles’ disappointment.

Books of magic have a sort of life of their own. Some have altogether too much; for example, the first edition of the Necrotelicomnicon has to be kept between iron plates, the True Arte of Levitatione has spent the last one hundred and fifty years up in the rafters, and Ge Fordge’s Compenydyum of Sex Majick is kept in a vat of ice in a room all by itselfand there’s a strict rule that it can only be read by wizards who are over eighty and, if possible, dead.

In most old libraries the books are chained to the shelves to prevent them being damaged by people. In the Library of Unseen University, of course, it’s more or less the other way about.
The Librarian ambled back down the aisles. He had a face that only a lorry tyre could love.
There are eight levels of wizardry on the Disc; after sixteen years Rincewind has failed to achieve even level one. In fact it is the considered opinion of some of his tutors that he is incapable even of achieving level zero, which most normal people are born at; to put it another way, it has been suggested that when Rincewind dies the average occult ability of the human race will actually go up by a fraction.

On top of the wardrobe, wrapped in scraps of yellowing paper and old dust sheets, was a large brass-bound chest. It went by the name of the Luggage. Why it consented to be owned by Rincewind was something only the Luggage knew, and it wasn’t telling, but probably no other item in the entire chronicle of travel accessories had quite such a history of mystery and grievous bodily harm. It had been described as half suitcase, half homicidal maniac. It had many unusual qualities … but currently there was only one that set it apart from any other brass-bound chest. It was snoring, with a sound like someone very slowly sawing a log.

The Luggage might be magical. It might be terrible. But in its enigmatic soul it was kin to every other piece of luggage throughout the multiverse, and preferred to spend its winters hibernating on top of a wardrobe.

But it wasn’t the sight of the cockroaches that was so upsetting. It was the fact that they were marching in step, a hundred abreast … There was something particularly unpleasant about the sound of billions of very small feet hitting the stones in perfect time.
Rincewind stepped gingerly over the marching column … The Luggage, of course, followed them with a noise like someone tap-dancing over a bag of crisps.

There was a lot of beer about. Here and there red-faced wizards were happily singing ancient drinking songs which involved a lot of knee-slapping and cries of ‘Ho!’ The only possible excuse for this sort of thing is that wizards are celibate, and have to find their amusement where they can.

The higher levels of wizardry are a perilous place. Every wizard is
