'Is this the same kind of water that floats through the sky and gouges out big caves in rocks?' said the Dean. 'Er . . . yes . . . er, obviously,' said Rincewind. 'It's good luck for us we only have the drinking and washing sort, then.'
'Had,' said Rincewind. There were hurrying feet behind them and a junior wizard ran up, holding a plate covered with a lid. 'Got the last one!' he said. 'It's a gourmet pie, too.' He lifted the lid. Rincewind stared, and swallowed. 'Oh dear . . .'
'What's up?'
'Have you got some more of that beer? I think I might be losing . . . concentration . . .' His cousin stepped forward, ripping the top off a can of Funnel web. 'Cartwright, you cover that pie up and keep it warm. Rincewind, you drink this.' They watched him drain the tin. 'Right, mate,' said the Archchancellor. 'How about a nice meat pie upside down in a big bowl of mushy green peas covered with tomato sauce?' He looked at the colour change on Rincewind's face, and nodded. 'You need another tin,' he said firmly. They watched him drink this. 'Okay,' said the Archchancellor after a while. 'Now, Rincewind, how about a nice one of Fair Go's pie floaters, eh? Meat pie in pea soup and tomato sauce?' Rincewind's face twitched a bit as amber blessings shut down vital protective systems. 'Sounds . . . good,' he said. 'Maybe with some coconut on the top?' The wizards relaxed. 'So now we know,' said Archchancellor Rincewind. 'We've got to keep you just drunk enough so that Dibbler's pies sound tasty, but not so drunk that it causes lasting brain damage.'
'That's a very narrow window we've got there,' said the Dean. Bill looked up at the roof, where the shadows danced among the stalactites, unless they were stalagmites. 'This is right under the city,' he said. 'How come we've never heard of it?'
'Good question,' said the Dean. The men who built the cellar must've seen it.' Rincewind tried to think. 'It wasn't here then,' he said.
'You said these stalag things took thousands of—'
'They probably weren't here last month but now they've been here for thousands of years.' said Rincewind. He hiccuped. 'It's like your tower,' he said. Taller onna outside.'
'Huh?'
'Prob'ly only works here,' said Rincewind. The more geography you've got, the less hist'ry, ever notice that? More space, less time. I bet it only took a second or two for this place to be here for thousands of years, see? Shorter on the outside. Makes serfect pense.'
'I don't think I've drunk enough beer to understand that,' said the Dean. Something nudged him in the back of the legs. He looked down at the Luggage. It was one of its habits to come up so close behind people that, when they looked down, they felt seriously over-feeted. 'Or this,' he added. The wizards grew quieter as Rincewind led them onward. He wasn't sure who was leading him. Still, no worries. Contrary to the usual procedures it began to grow lighter, although the proliferation of luminous fungi or iridescent crystals in deep caves where the torchlessly improvident hero needs to see is one of the most obvious intrusions of narrative causality into the physical universe. In this case, the rocks were glowing, not from some mysterious inner light but simply as though the sun were shining on them, just after dawn. There are other imperatives that operate on the human brain. One says: the bigger the space, the softer the voice, and refers to the natural tendency to speak very, very quietly when stepping into somewhere huge. So when Archchancellor Rincewind stepped out into the big cave he said, 'Strewth, it's bloody big!' in a low whisper. The Dean, however, shouted, 'Coo-eee!' because there's always one. Stalactites crowded the cave here, too, and in the very centre a gigantic stalactite had almost touched its mirror-image stalagmite. The air was chokingly hot. 'This isn't right—' said Rincewind. Plink. They spotted the source of the noise eventually. A tiny trickle was making its way down the side of the stalactite and forming droplets that fell a few feet to the stalagmite. Another drop formed while they watched, and hung there. One of the wizards clambered up the dry slope and peered at it. 'It's not moving,' he said. 'The trickle's drying up. I think . . . it's evaporating.'
The Archchancellor turned to Rincewind. 'Well, we've followed you this far, mate,' he said. 'What now?'
'I think I could do with another b—'
'There's none left, mate.' Rincewind looked desperately around the cave, and then at the huge translucent mass of limestone in front of him. It was definitely pointy. It was also in the centre of the cave. It had a certain inevitability about it. Odd, really, that something like this would form down here, shining away like a pearl in an oyster. The ground trembled again. Up there, people would already be getting thirsty, cursing the windmills as only an Ecksian could curse. The water was gone and that was very bad, and when the beer ran out people would really get angry . . . The wizards were all waiting for him to do something. All right, start with the rock. What did he know about rocks and caves in these parts? There was a curious freedom at a time like this. He was going to be in real trouble whatever he did, so he might as well give this a try . . . 'I need some paint,' he said. 'What for?'
'For what I need,' said Rincewind. 'There's young Salid,' said the Dean. 'He's a bit of an arty blager. Let's go and kick his door down.'
'And bring some more beer!' Rincewind called after them. Neilette patted Rincewind on the shoulder. 'Are you going to do some magic?' she said. 'I don't know if it counts as magic here,' said Rincewind. 'If it doesn't work, stand well back.'
'Is it going to be dangerous, then?'
'No, I might have to start running without looking where I'm going. But . . . this rock's warm. Have you noticed?' She touched it. 'I see what you mean . . .'
'I was just thinking . . . Supposing someone was in a country who shouldn't be there? What would it do?'
