“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? Look.”
Rincewind looked.
In front of him was a soft black night whose mist-muted stars glowed peacefully. But his eyes turned downward, 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 toward 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 itself out of the foam in a wild, jerky and ultimately hopeless leap. Then it fell back, over and over, in the golden underworld light.
Huge shadows grew out of that light like pillars supporting the roof of the universe. Hundreds of miles below him the wizard made out the shape of something, the edge of something—
Like those curious little pictures where the silhouette of an ornate glass suddenly becomes the outline of two faces, the scene beneath him flipped into a whole, new, terrifying perspective. Because down there was the head of an elephant as big as a reasonablysized continent. One mighty tusk cut like a mountain against the golden light, trailing a widening shadow toward the stars. The head was slightly tilted, and a huge ruby eye might almost have been a red supergiant that had managed to shine at noonday.
Below the elephant—
Rincewind swallowed and tried not to think—
Below the elephant there was nothing but the distant, painful Disc of the sun. And, sweeping slowly past it, was something that for all its city-sized scales, its crater-pocks, its Junar cragginess, was indubitably a flipper.
“Shall I let go?” suggested the troll.
“Gnah,” said Rincewind, straining backward.
“I have lived here on the Edge for five years and I have not had the courage,” boomed Tethis. “Nor have you, if I’m any judge.” He stepped back, allowing Rincewind to fling himself onto the ground.
Twoflower strolled up to the Rim and peered over.
“Fantastic,” he said. “If only I had my picture box…What else is down there? I mean, if you jumped off, what would you see?”
Tethis sat down on an outcrop. High over the Disc the moon came out from behind a cloud, giving him the appearance of ice.
“My home is down there, perhaps,” he said slowly. “Beyond your silly elephants and that ridiculous turtle. A real world. Sometimes I come out here and look, but somehow I can never bring myself to take that extra step…A real world, with real people. I have wives and little ones, somewhere down there…” He stopped, and blew his nose. “You soon learn what you’re made of, here on the Edge.”
“Stop saying that. Please,” moaned Rincewind. He turned over and saw Twoflower standing unconcernedly at the very lip of the rock. “Gnah,” he said, and tried to burrow into the stone.
“There’s another world down there?” said Twoflower, peering over. “Where, exactly?”
The troll waved an arm vaguely. “Somewhere,” he said. “That’s all I know. It was quite a small world. Mostly blue.”
“So why are you here?” said Twoflower.
“Isn’t it obvious?” snapped the troll. “I fell off the edge!”
He told them of the world of Bathys, somewhere among the stars, where the seafolk had built a number of thriving civilizations in the three large oceans that sprawled across its Disc. He had been a meatman, one of the caste which earned a perilous living in large, sail-powered land yachts that ventured far out to land and hunted the shoals of deer and buffalo that abounded in the storm-haunted continents. His particular yacht had been blown into uncharted lands by a freak gale. The rest of the crew had taken the yacht’s little rowing trolley and had struck out for a distant lake, but Tethis, as master, had elected to remain with his vessel. The storm had carried it right over the rocky rim of the world, smashing it to matchwood in the process.
“At first I fell,” said Tethis, “but falling isn’t so bad, you know. It’s only the landing that hurts, and there was nothing below me. As I fell I saw the world spin off into space until it was lost against the stars.”
