The Colour of Magic

which—in return—”
    “Yes? My memory is not what it used to be,” purred the Arch-astronomer, stroking the warm bronze.
    “In return,” continued Dactylos, without much apparent hope, “you would set me free, and refrain from chopping off any appendages. I require no treasure.”
    “Ah, yes. I recall now.” The old man raised a blue-veined hand, and added, “I lied.”
    There was the merest whisper of sound, and the goldeneyed man rocked on his feet. Then he looked down at the arrowhead protruding from his chest, and nodded wearily. A speck of blood bloomed on his lips.
    There was no sound in the entire square (save for the buzzing of a few expectant flies) as his silver hand came up, very slowly, and fingered the arrowhead.
    Dactylos grunted.
    “Sloppy workmanship,” he said, and toppled backward.
    The Arch-astronomer prodded the body with his toe, and sighed.
    “There will be a short period of mourning, as befits a master craftsman,” he said. He watched a bluebottle alight on one golden eye and fly away puzzled…“That would seem to be long enough,” said the Arch-astronomer, and beckoned a couple of slaves to carry the corpse away.
    “Are the chelonauts ready?” he asked.
    The master launchcontroller bustled forward.
    “Indeed, your prominence,” he said.
    “The correct prayers are being intoned?”
    “Quite so, your prominence.”
    “How long to the doorway?”
    “The launch window,” corrected the master launchcontroller carefully. “Three days, your prominence. Great A’Tuin’s tail will be in an unmatched position.”
    “Then all that remains,” concluded the Arch-astronomer, “is to find the appropriate sacrifices.”
    The master launchcontroller bowed.
    “The ocean shall provide,” he said.
    The old man smiled. “It always does,” he said.

    “If only you could navigate—”
    “If only you could steer—”
    A wave washed over the deck. Rincewind and Twoflower looked at each other. “Keep bailing!” they screamed in unison, and reached for the buckets.
    After a while Twoflower’s peevish voice filtered up from the waterlogged cabin.
    “I don’t see how it’s my fault,” he said. He handed up another bucket, which the wizard tipped over the side.
    “You were supposed to be on watch,” snapped Rincewind.
    “I saved us from the slavers, remember,” said Twoflower.
    “I’d rather be a slave than a corpse,” replied the wizard. He straightened up and looked out to sea. He appeared puzzled.
    He was a somewhat different Rincewind from the one that escaped the fire of Ankh-Morpork some six months before. More scarred, for one thing, and much more traveled. He had visited the Hublands, discovered the curious folkways of many colorful peoples—invariably obtaining more scars in the process—and had even, for a never-to-be-forgotten few days, sailed on the legendary Dehydrated Ocean at the heart of the incredibly dry desert known as the Great Nef. On a colder and wetter sea he had seen floating mountains of ice. He had ridden on an imaginary dragon. He had very nearly said the most powerful spell on the Disc. He had—
    —there was definitely less horizon than there ought to be.
    “Hmm?” said Rincewind.
    “I said nothing’s worse than slavery,” said Twoflower. His mouth opened as the wizard flung his bucket far out to sea and sat down heavily on the waterlogged deck, his face a gray mask.
    “Look, I’m sorry I steered us into the reef, but this boat doesn’t seem to want to sink and we’re bound to strike land sooner or later,” said Twoflower comfortingly. “This current must go somewhere.”
    “Look at the horizon,” said Rincewind, in a monotone.
    Twoflower squinted.
    “It looks all right,” he said after a while. “Admittedly, there seems to be less than there usually is, but—”
    “That’s because of the Rimfall,” said Rincewind. “We’re being carried over the edge of the world.”
    There was a long silence, broken only by the lapping of the waves as the foundering ship spun slowly in the current. It was already quite strong.
    “That’s probably why we hit that reef,” Rincewind added. “We got pulled off course during the night.”
    “Would you like something to eat?” asked Twoflower. He began to rummage through the bundle that he had tied to the rail, out of the damp.
    “Don’t you understand?” snarled Rincewind. “We are going over the Edge , godsdammit!”
    “Can’t we do anything about
