A crude floating stockade had been built out of rough timber on the hubward side of the island. It contained one or two hulks and quite a large amount of floating wood in the form of planks, baulks and even whole natural tree trunks, some still sporting green leaves. This close to the Edge the Disc’s magical field was so intense that a hazy corona flickered across everything as raw illusion spontaneously discharged itself.
With a last few squeaky jerks the boat slid up against a small driftwood jetty. As it grounded itself and formed a circuit Rincewind felt all the familiar sensations of a huge occult aura—oily, bluish-tasting, and smelling of tin. All around them pure, unfocused magic was sleeting soundlessly into the world.
The wizard and Twoflower scrambled onto the planking and for the first time Rincewind saw the troll.
It wasn’t half so dreadful as he had imagined.
Umm, said his imagination after a while.
It wasn’t that the troll was
‘It’s rude to stare,’ said the troll. Its mouth opened with a little crest of foam, and shut again in exactly the same way that water closes over a stone.’
‘Is it? Why?’ asked Rincewind. How does he hold himself together, his mind screamed at him. Why doesn’t he spill?
‘If you will follow me to my house I will find you food and a change of clothing,’ said the troll solemnly. He set off over the rocks without turning to see if they would follow him. After all, where else could they go? It was getting dark, and a chilly damp breeze was blowing over the edge of the world. Already the transient Rimbow had faded and the mists above the waterfall were beginning to thin.
‘Come on,’ said Rincewind, grabbing Twoflower’s elbow. But the tourist didn’t appear to want to move.
‘Come on,’ the wizard repeated.
‘When it gets really dark, do you think we’ll be able to look down and see Great A’tuin the World Turtle?’ asked Twoflower, staring at the rolling clouds.
‘I hope not,’ said Rincewind, ‘I really do. Now let’s go, shall we?’
Twoflower followed him reluctantly into the shack. The troll had lit a couple of lamps and was sitting comfortably in a rocking chair. He got to his feet as they entered and poured two cups of a green liquid from a tall pitcher. In the dim light he appeared to phosphoresce, in the manner of warm seas on velvety summer nights. Just to add a baroque gloss to Rincewind’s dull terror he seemed to be several inches taller, too.
Most of the furniture in the room appeared to be boxes.
‘Uh. Really great place you’ve got here,’ said Rincewind. ‘Ethnic.’
He reached for a cup and looked at the green pool shimmering inside it. It’d better be drinkable, he thought. Because I’m going to drink it. He swallowed.
It was the same stuff Twoflower had given him in the rowing boat but, at the time, his mind had ignored it because there were more pressing matters. Now it had the leisure to savour the taste.
Rincewind’s mouth twisted. He whimpered a little. One of his legs came up convulsively and caught him painfully in the chest.
Twoflower swirled his own drink thoughtfully while he considered the flavour.
‘Ghlen Livid,’{40} he said. ‘The fermented
‘All things drift into the Circumfence in time,’ said the troll, gnomically, gently rocking in his chair. ‘My job is to recover the flotsam. Timber, of course, and ships. Barrels of wine. Bales of cloth. You.’
Light dawned inside Rincewind’s head.
‘It’s a net, isn’t it? You’ve got a net right on the edge of the sea!’
‘The Circumfence,’ nodded the troll. Ripples ran across his chest.
Rincewind looked out into the phosphorescent darkness that surrounded the island, and grinned inanely.
‘Of course,’ he said. ‘Amazing! You could sink piles and attach it to reefs and—good grief! The net would have to be
‘It is,’ said Tethis.
‘It could be extended for a couple of miles, if you found enough rocks and things,’ said the wizard.
‘Ten thousands of miles. I just patrol this league.’
‘That’s a third of the way around the disc!’
Tethis sloshed a little as he nodded again. While the two men helped themselves to some more of the green wine, he told them about the Circumfence, the great effort that had been made to build it, and the ancient and wise Kingdom of Krull which had constructed it several centuries before, and the seven navies that patrolled it constantly to keep it in repair and bring its salvage back to Krull, and the manner in which Krull had become a land of leisure ruled by the most learned seekers after knowledge, and the way in which they sought constantly to understand in every possible particular the wondrous complexity of the universe, and the way in which sailors marooned on the Circumfence were turned into slaves, and usually had their tongues cut out. After some interjections at this point he spoke, in a friendly way, on the futility of force, the impossibility of escaping from the island except by boat to one of the other three hundred and eighty isles that lay between the island and Krull itself, or by leaping over the Edge, and the high merit of muteness in comparison to, for example, death.
There was a pause. The muted night-roar of the Rimfall only served to give the silence a heavier texture.
Then the rocking chair started to creak again. Tethis seemed to have grown alarmingly during the monologue.
‘There is nothing personal in all this,’ he added. ‘I too am a slave. If you try to overpower me I shall have to kill you, of course, but I won’t take any particular pleasure in it.’
Rincewind looked at the shimmering fists that rested lightly in the troll’s lap. He suspected they could strike with all the force of a tsunami.
‘I don’t think you understand,’ explained Twoflower. ‘I am a citizen of the Golden Empire. I’m sure Krull would not wish to incur the displeasure of the Emperor.’
‘How will the Emperor know?’ asked the troll. ‘Do you think you’re the first person from the Empire who has ended up on the Circumfence?’
‘I won’t be a slave!’ shouted Rincewind. ‘I’d—I’d jump over the Edge first!’ He was amazed at the sound in his own voice.
‘Would you, though?’ asked the troll. The rocking chair flicked back against the wall and one blue arm caught the wizard around the waist. A moment later the troll was striding out of the shack with Rincewind gripped carelessly in one fist.
He did not stop until he came to the Rimward edge of the island. Rincewind squealed.
‘Stop that or I really will throw you over the edge,’ snapped the troll. ‘I’m holding you, aren’t I?
Rincewind looked.
In front of him was a soft black night whose mist-muted stars glowed peacefully. But his eyes turned downwards, drawn by some irresistible fascination.
It was midnight on the Disc and so, therefore, the sun was far, far below, swinging slowly under Great A’Tuin’s vast and frosty plastron. Rincewind tried a last attempt to fix his gaze on the tips of his boots, which were protruding over the rim of the rock, but the sheer drop wrenched it away.
On either side of him two glittering curtains of water hurtled towards infinity as the sea swept around the island on its way to the long fall. A hundred yards below the wizard the largest sea salmon he had ever seen flicked
