Equal Rites (Discworld 3)
They flew in silence for a moment.
“Nevertheless,” said Granny thoughtfully, “I think that, on the whole, I would prefer you to move your hands.”
Rain gushed across the leads of Unseen University and poured into the gutters where ravens' nests, abandoned since the summer, floated like very badly-built boats. The water gurgled along ancient, crusted pipes. It found its way under tiles and said hallo to the spiders under the eaves. It leapt from gables and formed secret lakes high amongst the spires.
Whole ecologies lived in the endless rooftops of the University, which by comparison made Gormenghast look like a toolshed on a railway allotment; birds sang in tiny jungles grown from apple pips and weed seeds, little frogs swam in the upper gutters, and a colony of ants were busily inventing an interesting and complex civilisation.
One thing the water couldn't do was gurgle out of the ornamental gargoyles ranged around the roofs. This was because the gargoyles wandered off and sheltered in the attics at the first sign of rain. They held that just because you were ugly it didn't mean you were stupid.
It rained streams. It rained rivers. It rained seas. But mainly it rained through the roof of the Great Hall, where the duel between Granny and Cutangle had left a very large hole, and Treatle felt that it was somehow raining on him personally.
He stood on a table organising the teams of students who were taking down the paintings and ancient tapestries before they got soaked. It had to be a table, because the floor was already several inches deep in water.
Not rainwater, unfortunately. This was water with real personality, the kind of distinctive character water gets after a long journey through silty countryside. It had the thick texture of authentic Ankh water - too stiff to drink, too runny to plough.
The river had burst its banks and a million little watercourses were flowing backwards, bursting in through the cellars and playing peekaboo under the flagstones. There was the occasional distant boom as some forgotten magic in a drowned dungeon shorted out and surrendered up its power; Treatle wasn't at all keen on some of the unpleasant bubblings and hissings that were escaping to the surface.
He thought again how nice it would be to be the sort of wizard who lived in a little cave somewhere and collected herbs and thought significant thoughts and knew what the owls were saying. But probably the cave would be damp and the herbs would be poisonous and Treatle could never be sure, when all was said and done, exactly what thoughts were really significant.
He got down awkwardly and paddled through the dark swirling waters. Well, he had done his best. He'd tried to organise the senior wizards into repairing the roof by magic, but there was a general argument over the spells that could be used and a consensus that this was in any case work for artisans.
That's wizards for you, he thought gloomily as he waded between the dripping arches, always probing the infinite but never noticing the definite, especially in the matter of household chores. We never had this trouble before that woman came.
o;Ah, but it wasn't the same river.”
“It wasn't?”
“No.”
Cutangle shrugged. “It looked like the same bloody river.”
“No need to take that tone,” said Granny. “I don't see why I should listen to that sort of language from a wizard who can't even answer letters!”
Cutangle was silent for a moment, except for the castanet chatter of his teeth.
“Oh,” he said. “Oh, I see. They were from you, were they?”
“That's right. I signed them on the bottom. It's supposed to be a sort of clue, isn't it?”
“All right, all right. I just thought they were a joke, that's all,” said Cutangle sullenly.
“A joke?”
“We don't get many applications from women. We don't get any.”
“I wondered why I didn't get a reply,” said Granny.
“I threw them away, if you must know.”
“You could at least have - there it is!”
“Where? Where? Oh, there.”
The fog parted and they now saw it clearly - a fountain of snowflakes, a ornamental pillar of frozen air. And below it....
The staff wasn't locked in ice, but lay peacefully in a seething pool of water.
One of the unusual aspects of a magical universe is the existence of opposites. It has already been remarked that darkness isn't the opposite of light, it is simply the absence of light. In the same way absolute zero is merely the absence of heat. If you want to know what real cold is, the cold so intense that water can't even freeze but anti-boils, look no further than this pool.
