'Is he one of ours?'

'Looking like that?'

'Let's get him!'

'Why?'

' 'Cos he's running away!'

'Let him run.'

'Maybe he's got money. Anyway, what's he running away for?'

Rincewind slid down into another gully. Of all the luck! Soldiers should be where they were expected to be. What had happened to duty and honour and stuff like that?

The gully had dead grass and moss in the bottom.

He stood still and listened to the voices of the two men.

The air was stifling. It was as if the oncoming storm was pushing all the hot air in front of it, turning the plain into a pressure cooker.

And then the ground creaked, and sagged suddenly.

The faces of the absentee soldiers appeared over the edge of the gully.

There was another creak and the ground sank another inch or two. Rincewind didn't dare breathe in, in case the extra weight of air made him too heavy. And it was very clear that the least activity, such as jumping, was going to make things worse...

Very carefully, he looked down.

The dead moss had given way. He seemed to be standing on a baulk of timber buried in the ground, but dirt pouring around it suggested that there was a hole beneath.

It was going to give way any second n—

Rincewind threw himself forward. The ground fell away underneath so that, instead of standing on a slowly breaking piece of timber, he was hanging with his arms over what felt like another concealed log and, by the feel of it, one which was as riddled with rot as the first one.

This one, possibly out of a desire to conform, began to sag.

And then jolted to a stop.

The faces of the soldiers vanished backwards as the sides of the gully began to slide. Dry earth and small stones slid past Rincewind. He could feel them rattle on his boots and drop away.

He felt, as an expert in these things, that he was over a depth. From his point of view, it was also a height.

The log began to shift again.

This left Rincewind with, as he saw it, two options. He could let go and plunge to an uncertain fate in the darkness, or he could hang on until the timber gave way, and then plunge to an uncertain fate in the darkness.

And then, to his delight, there was a third option. The toe of his boot touched something, a root, a protruding rock. It didn't matter. It took some of his weight. It took at least enough to put him in precarious equilibrium - not exactly safe, not exactly falling. Of course, it was only a temporary measure, but Rincewind had always considered that life was no more than a series of temporary measures strung together.

A pale yellow butterfly with interesting patterns on its wings fluttered along the gully and settled on the only bit of colour available, which turned out to be Rincewind's hat.

The wood sagged slightly.

'Push off!' said Rincewind, trying not to use heavy language. 'Go away.''

The butterfly flattened its wings and sunned itself. Rincewind pursed his lips and tried to blow up his own nostrils.

Startled, the creature skittered into the air...

'Hah!' said Rincewind.

... and, in response to its instincts in the face of a threat, moved its wings like this and this.

The bushes shivered. And around the sky, the towering clouds curved into unusual patterns.

Another cloud formed. It was about the size of an angry grey balloon. And it started to rain. Not rain generally, but specifically. Specifically on about a square foot of ground which contained Rincewind; specifically, on his hat.

A very small bolt of lightning stung Rincewind on the nose.

'Ah! So we have' - Pink Pig, appearing around the curve of the gully, hesitated a bit before continuing slightly more thoughtfully - 'a head in a hole... with a very small thunderstorm above it.'

And then it dawned on him that, storm or no storm, nothing was preventing him from cutting off significant parts. The only significant part available was a head, but that was fine by him.

At which point, Rincewind's hat having absorbed enough moisture, the ancient wood gave way under the strain and plunged him to an uncertain fate in the darkness.

It was utterly dark.

There had been a painful confusion of tunnels and sliding dirt. Rincewind assumed - or the small part of him that was not sobbing with fear assumed - that the earth had caved in after him. Cave. That was a significant word. He was in a cave. Reaching out carefully, in case he felt something, he felt for something to feef.

There was a straight edge. It led to three more straight edges, going off at right angles. So... this meant slab.

The darkness was still a choking velvet shroud.

Slab meant that there was some other entrance, some proper entrance. Even now guards were probably hurrying towards him.

Perhaps the Luggage was hurrying towards them. It had been acting very funny lately, that was for certain. He was probably better off without it. Probably.

He patted his pockets, saying the mantra that even non-wizards invoke in order to find matches; that is. he said, 'Matches, matches, matches,' madly to himself, under his breath.

He found some, and scratched one desperately with his thumbnail.

'Ow!'

The smoky yellow flame lit nothing except Rince-wind's hand and part of his sleeve.

He ventured a few steps before it burned his fingers, and when it died it left a blue afterglow in the darkness of his vision.

There were no sounds of vengeful feet. There were no sounds at all. In theory there should be the drip of water, but the air felt quite dry.

He tried another match, and this time raised it as high as he could and peered ahead.

A seven-foot warrior smiled at him.

Cohen looked up again.

'It's going to piss down in a minute,' he said. 'Will you look at that sky?'

There were hints of purple and red in the mass, and the occasional momentary glow of lightning somewhere inside the clouds.

'Teach?'

'Yes?'

'You know everything. Why's that cloud looking like that?'

Mr Saveloy looked where Cohen was pointing. There was a yellowish cloud low on the horizon. Right around the horizon - one thin streak, as though the sun was trying to find a way through.

'Could be the lining?' said Boy Willie.

'What lining?'

'Every cloud's supposed to have a silver one.'

'Yeah, but that's more like gold.'

'Well, gold's cheaper here.'

'Is it me,' said Mr Saveloy, 'or is it getting wider?'

Caleb was staring at the enemy lines.

There's been a lot of blokes galloping about on their little horses,' he said. 'I hope they get a move on. We don't want to be here all day.'

'I vote we rushes 'em while they're not expectin' it,' said Hamish.

'Hold on... hold on...' said Truckle. There was the sound of many gongs being beaten, and the crackling of fireworks. 'Looks like the bas— the lovechilds are moving.'

'Thank goodness for that,' said Cohen. He stood up and stubbed out his cigarette.

Mr Saveloy trembled with excitement.

'Do we sing a song for the gods before we go into battle?' he said.

'You can if you like,' said Cohen.

'Well, do we say any heathen chants or prayers?'

'Shouldn't think so,' said Cohen. He glanced up at the horizon-girdling band. It was unsettling him far more than the approaching enemy. It was wider now, but slightly paler. For just a moment he found himself wishing that there was one god or goddess somewhere whose temple he hadn't violated, robbed or burned down.

'Don't we bang our swords on our shields and utter defiance?' said the teacher hopefully.

'Too late for that, really,' said Cohen.

Mr Saveloy looked so crestfallen at the lack of pagan splendour that the ancient barbarian was, to his own surprise, moved to add: 'But feel free, if that's what you want.'
