The children chorused a 'hello'. Clancy was scowling, looked about seven years old and was wearing a hard hat and a Pony Club badge.

I WASN'T EXPECTING TO SEE YOU HERE, RINCEWIND.

'Oh. Good.'

Death pulled an hourglass out of his robe, held it up to the moonlight, and sighed. Rincewind craned to see how much sand was left.

HOWEVER, I COULD-—

'Don't you make any special arrangement just on my account,' said Rincewind hurriedly. 'I, er... I expect you're all here for the battle?'

YES. IT PROMISES TO BE EXTREMELY - SHORT.

'Who's going to win?'

NOW, YOU KNOW I WOULDN'T TELL YOU THAT, EVEN IF I KNEW.

'Even if you knew?' said Rincewind. 'I thought you were supposed to know everything!'

Death held up a finger. Something fluttered down through the night. Rincewind thought it was a moth, although it looked less fluffy and had a strange speckled pattern on its wings.

It settled on the extended digit for a moment, and then flew up and away again.

ON A NIGHT LIKE THIS, said Death, THE ONLY CERTAIN THING IS UNCERTAINTY. TRITE, I KNOW, BUT TRUE.

Somewhere on the horizon, thunder rumbled.

'I'll, er, just be sort of going, then,' said Rincewind.

DON'T BE A STRANGER, said Death, as the wizard hurried off.

'Odd person,' said War.

WITH HIM HERE, EVEN UNCERTAINTY IS UNCERTAIN. AND I'M NOT SURE EVEN ABOUT THAT.

War pulled a large paper-wrapped package out of his saddlebag.

'We've got... let's see now... Egg and Cress, Chicken Tikka, and Mature Cheese with Crunchy Pickle, I think.'

THEY DO SUCH MARVELLOUS THINGS WITH SANDWICHES THESE DAYS.

'Oh... and Bacon Surprise.'

REALLY? WHAT IS SO SURPRISING ABOUT BACON?

'I don't know. I suppose it comes as something of a shock to the pig.'

Ridcully had been having a long wrestle with himself, and had won.

'We're going to bring him back,' he said. 'It's been four days. And then we can send them back their bloody tube thing. It gives me the willies.'

The senior wizards looked at one another. No-one was very keen on a university with a Rincewind component, but the metal dog did give them the willies. No-one had wanted to go near it. They'd piled some tables around it and tried to pretend it wasn't there.

'All right,' said the Dean. 'But Stibbons kept going on about things weighing the same, right? If we send that back, won't it mean Rincewind arrives here going very fast?'

'Mr Stibbons says he's working on the spell,' said Ridcully. 'Or we could pile some mattresses up at one end of the hall or something.'

The Bursar raised a hand.

'Yes, Bursar?' said Ridcully encouragingly.

'Ho, landlord, a pint of your finest ale!' said the Bursar.

'Good,' said Ridcully. 'That's settled, then. I've already told Mr Stibbons to start looking...'

'On that demonic device?'

'Yes.'

Then nothing can possibly go wrong,' said the Dean sourly.

'A trumpet of lobsters, if you would be so good.'

'And the Bursar agrees.'

The warlords had gathered in Lord Hong's chambers. They carefully kept a distance from one another, as befitted enemies who were in the most shaky of alliances. Once the barbarians were dealt with, the battle might still continue. But they wanted assurance on one particular point.

'No!' said Lord Hong. 'Let me make this absolutely clear! There is no invisible army of blood-sucking ghosts, do you understand? The people beyond the Wall are just like us - except vastly inferior in every respect, of course. But totally visible.'

One or two of the lords did not look convinced.

'And all this talk about the Red Army?' said one of them.

'The Red Army, Lord Tang, is an undisciplined rabble that shall be put down with resolute force!'

'You know what Red Army the peasants are talking about,' said Lord Tang. 'They say that thousands of years ago it—'

'They say that thousands of years ago a wizard who did not exist took mud and lightning and made soldiers that couldn't die,' said Lord Hong. 'Yes. It's a story, Lord Tang. A story made up by peasants who did not understand what really happened. One Sun Mirror's army just had' - Lord Hong waved a hand vaguely - 'better armour, better discipline. I am not frightened of ghosts and I am certainly not afraid of a legend that probably never existed.'

'Yes, but—'

'Soothsayer!' snapped Lord Hong. The soothsayer, who hadn't been expecting it, gave a start.

'Yes, my lord?'

'How're those entrails coming along?'

'Er - they're about ready, my lord,' said the soothsayer.

The soothsayer was rather worried. This must have been the wrong kind of bird, he told himself. About the only thing the entrails were telling him was that if he got out of this alive he, the soothsayer, might be lucky enough to enjoy a nice chicken dinner. But Lord Hong sounded like a man with the most dangerous kind of impatience.

'And what do they tell you?'

'Er - the future is... the future is...'

Chicken entrails had never looked like this. For a moment he thought they were moving.

'Er... it is uncertain,' he hazarded.

'Be certain,' said Lord Hong. 'Who will win in the morning?'

Shadows flickered across the table.

Something was fluttering around the light.

It looked like an undistinguished yellow moth, with black patterns on its wings.

The soothsayer's precognitive abilities, which were considerably more powerful than he believed, told him: this is not a good time to be a clairvoyant.

On the other hand, there was never a good time to be horribly executed, so...

'Without a shadow of doubt,' he said, 'the enemy will be most emphatically beaten.'

'How can you be so certain?' said Lord McSweeney.

The soothsayer bridled.

'You see this wobbly bit near the kidneys? You want to argue with this green trickly thing? You know all about liver suddenly? All right?'

'So there you are,' said Lord Hong. 'Fate smiles upon us.'

'Even so—' Lord Tang began. 'The men are very—'

'You can tell the men—' Lord Hong began. He stopped. He smiled.

'You can tell the men', he said, 'that there is a huge army of invisible vampire ghosts.'

'What?'

'Yes!' Lord Hong began to stride up and down, snapping his fingers. 'Yes, there is a terrible army of foreign ghosts. And this has so enraged our own ghosts... yes, a thousand generations of our ancestors are riding on the wind to repel this barbaric invasion! The ghosts of the Empire are arising! Millions and millions of them! Even our demons are furious at this intrusion! They will descend like a mist of claws and teeth to -Yes, Lord Sung?'

The warlords were looking at one another nervously.

'Are you sure, Lord Hong?'

Lord Hong's eyes gleamed behind his tiny spectacles.

'Make the necessary proclamations,' he said.

'But only a few hours ago we told the men there were no—'

'Tell them differently!'

'But will they believe that there—'

'They will believe what they are told!' shouted Lord Hong. 'If the enemy thinks his strength lies in deceit, then we will use their deceit against them. Tell the men that behind them will be a billion ghosts of the Empire!'

The other warlords tried to avoid his gaze. No-one was actually going to suggest that your average soldier would not be totally happy with ghosts front and rear, especially given the capriciousness of ghosts.

'Good,' said Lord Hong. He looked down.

'Are you still here?' he said.

'Just clearing up my giblets, my lord!' squealed the soothsayer.

He picked up the remains of his stricken chicken and ran for it.

After all, he told himself as he pelted back home, it's not as though I said whose enemy.
