There was hardly even a hiss, but three shreds of silk tumbled gently to the ground.

'Get back, Teach,' said Cohen slowly. 'I reckon this one's mine. Got another hanky? Thanks.'

The samurai looked at Cohen's sword. It was long, heavy and had so many notches it could have been used as a saw.

'You'll never do it,' he said. 'With that sword? Never.'

Cohen blew his nose noisily.

'You say?' he said. 'Watch this.'

The handkerchief soared into the air. Cohen gripped his sword...

He'd beheaded three upward-staring samurai before the handkerchief started to tumble. Other members of the Horde, who tended to think in much the same way as their leader, had accounted for half a dozen more.

'Got the idea from Caleb,' said Cohen. 'And the message is: either fight or muck about, it's up to you.'

'Have you no honour?' screamed Lord Hong. 'Are you just a ruffian?'

'I'm a barbarian,' shouted Cohen. 'And the honour I got, see, is mine. I didn't steal it off'f someone else.'

'I had wanted to take you alive,' said Lord Hong. 'However, I see no reason to stick to this policy.'

He drew his sword.

'Back, you scum!' he screamed. 'Right back! Let the bombardiers come forward!' He looked back at Cohen. His face was flushed. His spectacles were askew.

Lord Hong had lost his temper. And, as is always the case when a dam bursts, it engulfs whole countries.

The soldiers pulled back.

The Horde were, once again, in a widening circle.

'What's a bombardier?' said Boy Willie.

'Er, I believe it must mean people who fire some sort of projectile,' said Mr Saveloy. 'The word derives from—'

'Oh, archers,' said Boy Willie, and spat.

'Whut?'

'He said THEY'RE GOING TO USE ARCHERS, Hamish!'

'Heheh, we never let archers stop us at the Battle of Koom Valley!' cackled the antique barbarian.

Boy Willie sighed.

'That was between dwarfs and trolls, Hamish,' he said. 'And you ain't either. So whose side were you on?'

'Whut?'

'I said WHOSE SIDE WERE YOU ON?'

'I were on the side of being paid money to fight,' said Hamish.

'Best side there is.'

Rincewind lay on the floor with his hands over his ears.

The sound of thunder filled the underground chamber. Blue and purple light shone so brightly that he could see it through his eyelids.

Finally the cacophony subsided. There were still the sounds of the storm outside, but the light had faded to a blue-white glow, and the sound into a steady humming.

Rincewind risked rolling over and opening his eyes.

Hanging from rusted chains in the roof were big glass globes. Each one was the size of a man, and lightning crackled and sizzled inside, stabbing at the glass, seeking a way out.

At one time there must have been many more. But dozens of the big globes had fallen down over the years, and lay in pieces on the floor. There were still scores up there, swaying gently on their chains as the imprisoned thunderstorms fought for their freedom.

The air felt greasy. Sparks crawled over the floor and crackled on each angle.

Rincewind stood up. His beard streamed out as a mass of individual hairs.

The lightning globes shone down on a round lake of, to judge from the ripples, pure quicksilver. In the centre was a low, five-sided island. As Rincewind stared, a boat came drifting gently around to his side of the pool, making little slupslup noises as it moved through the mercury.

It was not a lot larger than a rowing boat and, lying on its tiny deck, was a figure in armour. Or possibly just the armour. If it was just empty armour, then it was lying in the arms-folded position of a suit of armour that has passed away.

Rincewind sidled around the silver lake until he reached a slab of what looked very much like gold, set in the floor in front of a statue.

He knew you got inscriptions in tombs, although he was never sure who it was who was supposed to read them. The gods, possibly, although surely they knew everything already? He'd never considered that they'd cluster round and say things like, 'Gosh, "Dearly Beloved" was he? I never knew that.'

This one simply said, in pictograms: One Sun Mirror.

There wasn't anything about mighty conquests. There was no list of his tremendous achievements. There was nothing down there about wisdom or being the father of his people. There was no explanation. Whoever knows this name, it seemed to say, knows everything. And there was no admitting the possibility that anyone getting this far would not have heard the name of One Sun Mirror.

The statue looked like porcelain. It had been painted quite realistically. One Sun Mirror seemed an ordinary sort of man. You would not have pointed him out in a crowd as Emperor material. But this man, with his little round hat and little round shield and little round men on little round ponies, had glued together a thousand warring factions into one great Empire, often using their own blood to do it.

Rincewind looked closer. Of course, it was just an impression, but around the set of the mouth and the look of the eyes there was an expression he'd last seen on the face of Ghenghiz Cohen.

It was the expression of someone who was absolutely and totally unafraid of anything.

The little boat headed towards the far side of the lake.

One of the globes flickered a little and then faded to red. It winked out. Another followed it.

He had to get out.

There was something else, though. At the foot of the statue, lying as if they'd just been dropped there, were a helmet, a pair of gauntlets, and two heavy-looking boots.

Rincewind picked up the helmet. It didn't look very strong, but it did look quite light. Normally he didn't bother with protective clothing, reasoning that the best defence against threatening danger was to be on another continent, but right now the idea of armour had its attractions.

He removed his hat, put the helmet on, pulled down the visor, and then wedged the hat on top of the helmet.

There was a flicker in front of his eyes and Rincewind was staring at the back of his own head. It was a grainy picture, and it was in shades of green rather than proper colours, but it was definitely the back of his own head he was looking at. People had told him what it looked like.

He raised the visor and blinked.

The pool was still in front of him.

He lowered the visor.

There he was, about fifty feet away, with this helmet on his head.

He waved a hand up and down.

The figure in the visor waved a hand up and down.

He turned around and faced himself. Yep. That was him.

OK, he thought. A magic helmet. It lets you see yourself a long way away. Great. You can have fun watching yourself fall into holes you can't see because they're right up close.

He turned around again, raised the visor and inspected the gloves. They seemed as light as the helmet but quite clumsy. You could hold a sword, but not much else.

He tried one on. Immediately, with a faint sizzling noise, a row of little pictures lit up on the wide cuff. They showed soldiers. Soldiers digging, soldiers fighting, soldiers climbing...

Ah. So... magic armour. Perfectly normal magic armour. It had never been very popular in Ankh-Morpork. Of course, it was light. You could make it as thin as cloth. But it tended to lose its magic without warning. Many an ancient lord's last words had been, 'You can't kill me because I've got magic aaargh.'

Rincewind looked at the boots, with suspicious recollection of the trouble there had been with the University's prototype Seven League boots. Footwear which tried to make you take steps twenty-one miles long imposed unfortunate groinal strains; they'd got the things off the student just in time, but he'd still had to wear a special device for several months, and ate standing up.
