The Dean hit first, striking an elf a blow with his staff. A horseshoe had been wired to the end.

The elf screamed and twisted back, clutching at its shoulder.

There were many elves but they hadn't been expecting an attack. And iron was so powerful. A

handful of flung nails had the effect of buckshot. Some tried to fight back, but the dread of iron was too strong.

The prudent and the survivors took to their skinny heels, while the dead evaporated.

The attack took less than thirty seconds. Rincewind watched it from behind his tree. He was not being cowardly, he reasoned. This was a job for specialists, and could safely be left to the senior wizards. If, later on, there was a problem involving slood dynamics or fretwork, or someone needed to misunderstand some magic, he would be happy to step forward.

There was a rustling behind him.

Something was there. What it was changed as he turned and stared. The first talent of the elves was their singing. It could turn other creatures into potential slaves. The second talent was their ability to change not their shape but how their shape was perceived. For a moment Rincewind caught sight of a slim, spare figure glaring at him and then, in one blurred moment, it became a woman. A queen, in a red dress and a rage.

'Wizards?' she said. 'Here? Why? How? Tell me!' A gold crown glittered in her dark hair and murder gleamed in her eyes as she advanced on Rincewind, who backed up against his tree. 'This is not your world!' the elf queen hissed. 'You'd be amazed,' said Rincewind. 'Now!' The queen's brow wrinkled. 'Now?' she repeated. 'Yes, I said now,' Rincewind said, grinning desperately.

'Now was the word I said, in fact. Now!'

For a moment the queen looked puzzled. And then she somersaulted backwards in a high arc, just as the Luggage's lid snapped shut where she had been. She landed behind it, hissed at Rincewind, and vanished into the night.

Rincewind glared at the box. 'Why did you wait? Did I tell you to wait?' he demanded. 'You just like to stand right behind people and wait for them to find out, right?'

He looked around. There was no sign of any more elves. In the middle distance the Dean, having run out of enemies, was attacking a tree.

Then Rincewind looked up. Along the branches, clinging to one another and staring down at him in wide-eyed amazement, were dozens of what looked, in the moonlight, like rather small and worried monkeys.

'Good evening!' he said. 'Don't worry about us, we're just passing through ...'

'Now this is where it all gets complicated,' said a voice behind him. It was a familiar one, being his own. 'I've only got a few seconds before the loop closes, so here's what you have to do. When you go back to Dee's time ... hold your breath.'

Are you me?' said Rincewind, peering into the gloom.

'Yes. And I'm telling you to hold your breath. Would I lie to me?'

There was an inrush of air as the other Rincewind disappeared and, down in the clearing, Ridcully bellowed Rincewind's name.

Rincewind stopped looking around and hurried down to the other wizards, who were looking immensely pleased with themselves.

Ah, Rincewind, I thought you wouldn't want to be left behind,' said the Archchancellor, grinning nastily. 'Got any, did you?'

'The queen, in fact,' said Rincewind. 'Really? I'm impressed!'

'But she - it got away.'

'They've all gone,' said Ponder. 'I saw a blue flash on that hill up there. They've gone back to their world.'

'D'you think they'll come back?' said Ridcully.

'It doesn't matter if they do, sir. Hex will spot them and we can always get there in time.'

Ridcully cracked his knuckles. 'Good. Capital exercise. Much better than magicking paint at one another. Builds grit and team interdependency. Someone go and stop the Dean attacking that rock, will you? He does rather get carried away.'

A faint white ring appeared on the grass, wide enough to hold the wizards.

'Ah, the ride back,' said the Archchancellor, as the excited Dean was hustled towards the rest of the group. 'Time to—'

The wizards were suddenly in empty air. They fell. All but one of them were not holding their breath before they hit the river.

Wizards do, however, have good floating capabilities and a tendency to bob up and down. And the river was in any case rather like a slowly moving swamp. Floating logs and mud banks choked it. Here and there, mud banks had become sufficiently established to sprout a crop of trees. By degrees, and with much arguing about where dry land actually began -it was not very obvious -they splashed their way to the shore. The sun was hot overhead, and clouds of mosquitoes shimmered among the trees.

'Hex has brought us back to the wrong time,' said Ridcully, wringing out his robe.

'I don't think he'd do that, Archchancellor,' said Ponder, meekly. 'The wrong place, then. This is not a city, in case you hadn't noticed.'

Ponder looked around in bewilderment. The landscape around them was not exactly land and not exactly river. Ducks were quacking, somewhere. There were blue hills in the distance.

'On the upside,' said Rincewind, extracting frogs from a pocket, 'everything smells better.'

'This is a swamp, Rincewind.'

'So?'

'And I can see smoke,' said Ridcully.

There was a thin grey column in the middle distance.

Reaching it took a lot longer than the mere distance suggested. Land and water were contesting every step of the way. But, eventually, and with only one sprain and a number of bites, the wizards reached some thick bushes and peered into the clearing beyond.

There were some houses, but that was stretching the term. They were little more than piles of branches with reed roofs.

'They could be savages,' said the Lecturer in Recent Runes.

'Or perhaps someone sent them all out into the country to forge a dynamic team spirit,' said the Dean, who had been badly bitten.

'Savages would be too much to hope for,' said Rincewind, watching the huts carefully.

'You want to find savages?' said Ridcully.

Rincewind sighed. 'I am the Professor of Cruel and Unusual Geography, sir. In an unknown situation, always hope for savages. They tend to be quite polite and hospitable provided you don't make any sudden moves or eat the wrong sort of animal.'

'Wrong sort of animal?' said Ridcully.

'Taboo, sir. They tend to be related. Or something.'

'That sounds rather ... sophisticated,' said Ponder suspiciously.

'Savages often are,' said Rincewind. 'It's the civilised people that give you trouble. They always want to drag you off somewhere and ask you unsophisticated questions. Edged weapons are often involved. Trust me on this. But these aren't savages, sir.'

'How can you tell?'

'Savages build better huts,' said Rincewind firmly. 'These are edge people.'

'I've never heard of edge people!' said Ridcully.

'I made it up,' said Rincewind. 'I run into them occasionally. People that live right on the edge, sir. Out on rocks. In the worst kind of desert. No tribe or clan. That takes too much effort. Of course, so does beating up strangers, so they're the best kind of people to meet.'

Ridcully looked around at the swamp. 'But there's waterfowl everywhere,' he said. 'Birds. Eggs.

Lots of fish, I'll be bound. Beavers. Animals that come down to drink. I could eat myself greasy to the eyebrows here. This is good country.'

'Hold on, one of them's coming out.' said the Lecturer in Recent Runes.

A stooping figure had emerged from a hut. It straightened up, and stared around. Huge nostrils flared.

'Oh my, look what just fell out of the ugly tree,' said the Dean. 'Is it a troll?'

'He's certainly a bit rugged,' said Ridcully. 'And why is he wearing boards?'

'I think he's just not very good at tanning hides,' said Rincewind.
