Against the Fall of Night

by Arthur C. Clarke

  Towards evening they caught occasional glimpses of the mountains ahead. The river that had been so faithful a guide was flowing sluggishly now, as if it too were nearing the end of its journey. But it was clear that they could not reach the mountains by nightfall: well before sunset the forest had become so dark that further progress was impossible. The great trees lay in pools of shadow, and a cold wind was sweeping through the leaves. Alvin and Theon settled down for the night beside a giant redwood whose topmost branches were still ablaze with sunlight.

  When at last the hidden sun went down, the light still lingered on the dancing waters. The two boys lay in the gathering gloom, watching the river and thinking of all that they had seen. As Alvin fell asleep, he found himself wondering who last had come this way, and how long since.

  The sun was high when they left the forest and stood at last before the mountain walls of Lys. Ahead of them the ground rose steeply to the sky in waves of barren rock. Here the river came to an end as spectacular as its beginning, for the ground opened in its path and it sank roaring from sight.

  For a moment Theon stood looking at the whirlpool and the broken land beyond. Then he pointed to a gap in the hills.

  “Shalmirane lies in that direction,” he said confidently. Alvin looked at him in surprise.

  “You told me you’d never been here before!”

  “I haven’t.”

  “Then how do you know the way?”

  Theon looked puzzled.

  “I don’t know—I’ve never thought about it before. It must be a kind of instinct, for wherever we go in Lys we always know our way about.”

  Alvin found this very difficult to believe, and followed Theon with considerable skepticism. They were soon through the gap in the hills, and ahead of them now was a curious plateau with gently sloping sides. After a moment’s hesitation. Theon started to climb. Alvin followed, full of doubts, and as he climbed he began to compose a little speech. If the journey proved in vain, Theon would know exactly what he thought of his unerring instinct.

  As they approached the summit, the nature of the ground altered abruptly. The lower slopes had consisted of porous, volcanic stone, piled here and there in great mounds of slag. Now the surface turned suddenly to hard sheets of glass, smooth and treacherous, as if the rock had once run in molten rivers down the mountain. The rim of the plateau was almost at their feet. Theon reached it first, and a few seconds later Alvin overtook him and stood speechless at his side. For they stood on the edge, not of the plateau they had expected, but of a giant bowl half a mile deep and three miles in diameter. Ahead of them the ground plunged steeply downwards, slowly levelling out at the bottom of valley and rising again, more and more steeply, to the opposite rim. And although it now lay in the full glare of the sun, the whole of that great depression was ebon black. What material formed the crater the boys could not even guess, but it was black as the rock of a world that had never known a sun. Nor was that all, for lying beneath their feet and ringing the entire crater was a seamless band of metal, some hundred feet wide, tarnished by immeasurable age but still showing no slightest trace of corrosion.

  As their eyes grew accustomed to the unearthly scene, Alvin and Theon realized that the blackness of the bowl was not as absolute as they had thought. Here and there, so fugitive that they could only see them indirectly, tiny explosions of light were flickering in the ebon walls. They came at random, vanishing as soon as they were born, like the reflections of stars on a broken sea.

  “It’s wonderful!” gasped Alvin. “But what is it?”

  “It looks like a reflector of some kind.”

  “I can’t imagine that black stuff reflecting anything.”

  “It’s only black to our eyes, remember. We don’t know what radiations they used.”

  “But surely there’s more than this! Where is the fortress?”

  Theon pointed to the level floor of the crater, where lay what Alvin had taken to be a pile of jumbled stones. As he looked again, he could make out an almost obliterated plan behind the grouping of the great blocks. Yes, there lay the ruins of once mighty buildings, overthrown by time.

  For the first few hundred yards the walls were too smooth and steep for the boys to stand upright, but after a little while they reached the gentler slopes and could walk without difficulty. Near the bottom of the crater the smooth ebony of its surface ended in a thin layer of soil, which the winds of Lys must have brought here through the ages.

  A quarter of a mile away, titanic blocks of stone were piled one upon the other, like the discarded toys of an infant giant. Here, a section of a massive wall was still recognizable: there, two carven obelisks marked what had once been a mighty entrance. Everywhere grew mosses and creeping plants, and tiny stunted trees. Even the wind was hushed.

  So Alvin and Theon came to the ruins of Shalmirane. Against those walls, if legend spoke the truth, forces that could shatter a world to dust had flamed and thundered and been utterly defeated. Once these peaceful skies had blazed with fires torn from the hearts of suns, and the mountains of Lys must have quailed like living things beneath the fury of their masters.

  No one had ever captured Shalmirane. But now the fortress, the impregnable fortress, had fallen at last—captured and destroyed by the patient tendrils of the ivy and the generations of blindly burrowing worms.

  Overawed by its majesty, the two boys walked in silence towards the colossal wreck. They passed into the shadow of a broken wall, and entered a canyon where the mountains of stone had split asunder.

  Before them lay a great amphitheater, crossed and criss-crossed with long mounds of rubble that must mark the graves of buried machines. Once the whole of this tremendous space had been vaulted, but the roof had long since collapsed. Yet life must still exist somewhere among the desolation, and Alvin realized that even this ruin might be no more than superficial. The greater part of the fortress would be far underground, beyond the reach of Time.

  “We’ll have to turn back by noon,” said Theon, “so we mustn’t stay too long. It would be quicker if we separated. I’ll take the eastern half and you can explore this side. Shout if you find anything interesting—but don’t get too far away.”

  So they separated, and Alvin began to climb over the rubble, skirting the larger mounds of stone. Near the center of the arena he came suddenly upon a small circular clearing, thirty or forty feet in diameter. It had been covered with weeds, but they were now blackened and charred by tremendous heat, so that they crumbled to ashes at his approach. At the centre of the clearing stood a tripod supporting a polished metal bowl, not unlike a model of Shalmirane itself. It was capable of movement in altitude and azimuth, and a spiral of some transparent substance was supported at its centre. Beneath the reflector was welded a black box from which a thin cable wandered away across the ground.

  It was clear to Alvin that this machine must be the source of the light, and he began to trace the cable. It was not too easy to follow the slender wire, which had a habit of diving into crevasses and reappearing at unexpected places. Finally he lost it altogether and shouted to Theon to come and help him.

  He was crawling under an overhanging rock when a shadow suddenly blotted out the light. Thinking it was his friend, Alvin emerged from the cave and turned to speak. But the words died abruptly on his lips.

  Hanging in the air before him was a great dark eye surrounded by a satellite system of smaller eyes. That, at least, was Alvin’s first impression: then he realized that he was looking at a complex machine—and it was looking at him.

  Alvin broke the painful silence. All his life he had given orders to machines, and although he had never seen anything quite like this creature, he decided that it was probably intelligent.

  “Reverse,” he ordered experimentally.

  Nothing happened.

  “Go. Come. Rise. Fall. Advance.”

  None of the conventional control thoughts produced any effect. The machine remained contemptuously inactive.

&nb
sp; Alvin took a step forward, and the eyes retreated in some haste. Unfortunately, their angle of vision seemed somewhat limited, for the machine came to a sudden halt against Theon, who for the last minute had been an interested spectator. With a perfectly human ejaculation, the whole apparatus shot twenty feet into the air, revealing a set of tentacles and jointed limbs clustering round a stubby cylindrical body.

  “Come down—we won’t hurt you!” called Theon, rubbing a bruise on his chest.

  Something spoke: not the passionless, crystal-clear voice of a machine, but the quavering speech of a very old and very tired man.

  “Who are you? What are you doing in Shalmirane?”

  “My name is Theon, and this is my friend, Alvin of Loronei. We’re exploring Southern Lys.”

  There was a brief pause. When the machine spoke again its voice held an unmistakable note of petulance and annoyance.

  “Why can’t you leave me in peace? You know how often I’ve asked to be left alone!”

  Theon, usually good-natured, bristled visibly.

  “We’re from Airlee, and we don’t know anything about Shalmirane.”

  “Besides,” Alvin added reproachfully, “we saw your light and thought you might be signalling for help.”

  It was strange to hear so human a sigh from the coldly impersonal machine.

  “A million times I must have signalled now, and all I have ever done is to draw the inquisitive from Lys. But I see you meant no harm. Follow me.”

  The machine floated slowly away over the broken stones, coming to rest before a dark opening in the ruined wall of the amphitheater. In the shadow of the cave something moved, and a human figure stepped into the sunlight. He was the first physically old man Alvin had ever seen. His head was completely bald, but a thick growth of pure white hair covered all the lower part of his face. A cloak of woven glass was thrown carelessly over his shoulders, and on either side of him floated two more of the strange, many-eyed machines.

  The Story of Shalmirane

  There was a brief silence while each side regarded the other. Then the old man spoke—and the three machines echoed his voice for a moment until something switched them off.

  “So you are from the North, and your people have already forgotten Shalmirane.”

  “Oh, no!” said Theon quickly, “we’ve not forgotten. But we weren’t sure that anyone still lived here, and we certainly didn’t know that you wished to be left alone.”

  The old man did not reply. Moving with a slowness that was painful to watch, he hobbled through the doorway and disappeared, the three machines floating silently after him. Alvin and Theon looked at each other in surprise: they did not like to follow, but their dismissal—if dismissal it was—had certainly been brusque. They were starting to argue the matter when one of the machines suddenly reappeared.

  “What are you waiting for? Come along!” it ordered. Then it vanished again.

  Alvin shrugged his shoulders.

  “We appear to be invited. I think our host’s a little eccentric, but he seems friendly.”

  From the opening in the wall a wide spiral stairway led downwards for a score of feet. It ended in a small circular room from which several corridors radiated. However, there was no possibility of confusion, for all the passages save one were blocked with debris.

  Alvin and Theon had walked only a few yards when they found themselves in a large and incredibly untidy room cluttered up with a bewildering variety of objects. One end of the chamber was occupied by domestic machines—synthesizers, destructors, cleaning equipment and the like—which one normally expected to be concealed from sight in the walls and floors. Around these were piled cases of thought records and transcribers, forming pyramids that reached almost to the ceiling. The whole room was uncomfortably hot owing to the presence of a dozen perpetual fires scattered about the floor. Attracted by the radiation, Krif flew towards the nearest of the metal spheres, stretched his wings luxuriously before it, and fell instantly asleep.

  It was a little while before the boys noticed the old man and his three machines waiting for them in a small open space which reminded Alvin of a clearing in the jungle. There was a certain amount of furniture here—a table and three comfortable couches. One of these was old and shabby, but the others were so conspicuously new that Alvin was certain they had been created in the last few minutes. Even as he watched, the familiar warning glow of the synthesizer field flickered over the table and their host waved silently towards it. They thanked him formally and began to sample the food and drink that had suddenly appeared. Alvin realized that he had grown a little tired of the unvarying output from Theon’s portable synthesizer and the change was very welcome.

  They ate in silence for a while, stealing a glance now and then at the old man. He seemed sunk in his own thoughts and appeared to have forgotten them completely—but as soon as they had finished he looked up and began to question them. When Alvin explained that he was a native not of Lys but of Diaspar, the old fellow showed no particular surprise. Theon did his best to deal with the queries: for one who disliked visitors, their host seemed very anxious to have news of the outer world. Alvin quickly decided that his earlier attitude must have been a pose.

  Presently he fell silent again. The two boys waited with what patience they could: he had told them nothing of himself or what he was doing in Shalmirane. The light-signal that had drawn them there was still as great a mystery as ever, yet they did not care to ask outright for an explanation. So they sat in an uncomfortable silence, their eyes wandering round that amazing room, finding something new and unexpected at every moment. At last Alvin broke into the old man’s reverie.

  “We must leave soon,” he remarked.

  It was not a statement so much as a hint. The wrinkled face turned towards him but the eyes were still very far away. Then the tired, infinitely ancient voice began to speak. It was so quiet and low that at first they could scarcely hear: after a while the old man must have noticed their difficulty, for of a sudden the three machines began once more to echo his words.

  Much that he told them they could never understand. Sometimes he used words which were unknown to them: at other times he spoke as if repeating sentences or whole speeches that others must have written long ago. But the main outlines of the story were clear, and they took Alvin’s thoughts back to the ages of which he had dreamed since his childhood.

  The tale began, like so many others, amid the chaos of the Transition Centuries, when the Invaders had gone but the world was still recovering from its wounds. At that time there appeared in Lys the man who later became known as the Master. He was accompanied by three strange machines—the very ones that were watching them now—which acted as his servants and also possessed definite intelligences of their own. His origin was a secret he never disclosed, and eventually it was assumed that he had come from space, somehow penetrating the blockade of the Invaders. Far away among the stars there might still be islands of humanity which the tide of war had not yet engulfed.

  The Master and his machines possessed powers which the world had lost, and around him he gathered a group of men to whom he taught much wisdom. His personality must have been a very striking one, and Alvin could understand dimly the magnetism that had drawn so many to him. From the dying cities, men had come to Lys in their thousands, seeking rest and peace of mind after the years of confusion. Here among the forests and mountains, listening to the Master’s words, they found that peace at last.

  At the close of his long life the Master had asked his friends to carry him out into the open so that he could watch the stars. He had waited, his strength waning, until the culmination of the Seven Suns. As he died the resolution with which he had kept his secret so long seemed to weaken, and he babbled many things of which countless books were to be written in future ages. Again and again he spoke of the “Great Ones” who had now left the world but who would surely one day return, and he charged his followers to remain to greet them when th
ey came. Those were his last rational words. He was never again conscious of his surroundings, but just before the end he uttered one phrase that revealed part at least of his secret and had come down the ages to haunt the minds of all who heard it: “It is lovely to watch the colored shadows on the planets of eternal light.” Then he died.

  So arose the religion of the Great Ones, for a religion it now became. At the Master’s death many of his followers broke away, but others remained faithful to his teachings, which they slowly elaborated through the ages. At first they believed that the Great Ones, whoever they were, would soon return to Earth, but that hope faded with the passing centuries. Yet the brotherhood continued, gathering new members from the lands around, and slowly its strength and power increased until it dominated the whole of Southern Lys.

  It was very hard for Alvin to follow the old man’s narrative. The words were used so strangely that he could not tell what was truth and what legend—if, indeed, the story held any truth at all. He had only a confused picture of generations of fanatical men, waiting for some great event which they did not understand to take place at some unknown future date.

  The Great Ones never returned. Slowly the power of the movement failed, and the people of Lys drove it into the mountains until it took refuge in Shalmirane. Even then the watchers did not lose their faith, but swore that however long the wait they would be ready when the Great Ones came. Long ago men had learned one way of defying Time, and the knowledge had survived when so much else had been lost. Leaving only a few of their number to watch over Shalmirane, the rest went into the dreamless sleep of suspended animation.

  Their numbers slowly falling as sleepers were awakened to replace those who died, the watchers kept faith with the Master. From his dying words it seemed certain that the Great Ones lived on the planets of the Seven Suns, and in later years attempts were made to send signals into space. Long ago the signalling had become no more than a meaningless ritual, and now the story was nearing its end. In a very little while only the three machines would be left in Shalmirane, watching over the bones of the men who had come here so long ago in a cause that they alone could understand.
