THE CRATER DWELLER

It was night when Alvin awoke, the utter night of mountain country, terrifying in its intensity. Something had disturbed him, some whisper of sound that had crept into his mind above the dull thunder of the falls. He sat up in the darkness, straining his eyes across the hidden land, while with indrawn breath he listened to the drumming roar of the falls and the faint but unending rustle of life in the trees around him.

Nothing was visible. The starlight was too dim to reveal the miles of country that lay hundreds of feet below: only a jagged line of darker night eclipsing the stars told of the mountains on the southern horizon. In the darkness beside him Alvin heard his friend roll over and sit up.

“What is it?” came a whispered voice.

“I thought I heard a noise.”

“What sort of noise?”

“I don’t know. Perhaps I was only dreaming.”

There was silence while two pairs of eyes peered out into the mystery of night. Then, suddenly, Theon caught his friend’s arm.

“Look!” he whispered.

Far to the south glowed a solitary point of light, too low in the heavens to be a star. It was a brilliant white, tinged with violet, and as the boys watched it began to climb the spectrum of intensity, until the eye could no longer bear to look upon it. Then it exploded-and it seemed as if lightning had struck below the rim of the world. For an instant the mountains, and the great land they guarded, were etched with fire against the darkness of the night. Ages later came the echo of a mighty explosion, and in the forest below a sudden wind stirred among the trees. It died away swiftly, and one by one the routed stars crept back into the sky.

For the first time in his life, Alvin knew that fear of the unknown that had been the curse of ancient Man. It was a feeling so strange that for a while he could not even give it a name. In the moment of recognition it vanished and he became himself again.

What is it?” he whispered.

There was a pause so long that he repeated the question.

“I’m trying to remember,” said Theon, and was silent for a while. A little later he spoke again.

“That must be Shalmirane,” he said simply.

“Shalmirane! Does it still exist?”

“I’d almost forgotten,” replied Theon, “but it’s coming back now. Mother once told me that the fortress lies in those mountains. Of course, it’s been in ruins for ages, but someone is still supposed to live there.”

Shalmirane! To these children of two races, so widely differing in culture and history, this was indeed a name of magic. In all the long story of Earth there had been no greater epic than the defense of Shalmirane against an invader who had conquered all the Universe.

Presently Theon’s voice came again out of the darkness.

“The people of the south could tell us more. We will ask them on our way back.”

Alvin scarcely heard him: he was deep in his own thoughts, remembering stories that Rorden had told him long ago. The Battle of Shalmirane lay at the dawn of recorded history: it marked the end of the legendary ages of Man’s conquests, and the beginning of his long decline. In Shalmirane, if anywhere on Earth, lay the answers to the problems that had tormented him for so many years. But the southern mountains were very far away.

Theon must have shared something of his mother’s powers, for he said quietly:

“If we started at dawn, we could reach the fortress by nightfall. I’ve never been there, but I think I could find the way.”

Alvin thought it over. He was tired, his feet were sore, and the muscles of his thighs were aching with the unaccustomed effort. It was very tempting to leave it until another time. Yet there might be no other time, and there was even the possibility that the actinic explosion had been a signal for help.

Beneath the dim light of the failing stars, Alvin wrestled with his thoughts and presently made his decision. Nothing had changed: the mountains resumed their watch over the sleeping land. But a turning-point in history had come and gone, and the human race was moving towards a strange new future.

The sun had just lifted above the eastern wall of Lys when they reached the outskirts of the forest. Here, Nature had returned to her own. Even Theon seemed lost among the gigantic trees that blocked the sunlight and cast pools of shadow on the jungle floor. Fortunately the river from the fall flowed south in a line too straight to be altogether natural, and by keeping to its edge they could avoid the denser undergrowth. A good deal of Theon’s time was spent in controlling Krif, who disappeared occasionally into the jungle or went skimming wildly across the water. Even Alvin, to whom everything was still so new, could feel that the forest had a fascination not possessed by the smaller, more cultivated woods of northern Lys. Few trees were alike: most of them were in various stages of devolution and some had reverted through the ages almost to their original, natural forms. Many were obviously not of Earth at all-perhaps not even of the Solar System. Watching like sentinels over the lesser trees were giant sequoias, three and four hundred feet high. They had once been called the oldest things on Earth: they were still a little older than Man.

The river was widening now: ever and again it opened into small lakes, upon which tiny islands lay at anchor. There were insects here, brilliantly colored creatures swinging aimlessly to and fro over the surface of the water. Once, despite Theon’s shouts, Krif darted away to join his distant cousins. He disappeared instantly in a cloud of glittering wings, and the sound of angry buzzing floated towards them. A moment later the cloud erupted and Krif came back across the water, almost too quickly for the eye to follow. Thereafter he kept very close to Theon and did not stray again.

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 the 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 crisscrossed 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 center 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 center. 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 thought produced any effect. The machine remained contemptuously inactive.

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.
