Arthur Clarke: Childhood’s End

“Many of the leaders are blind; they have been corrupted by the Overlords. When they realize the danger, it may be too late. Humanity will have lost its initiative and become a subject race.” There was silence for a moment. Then Stormgren replied:

“In three days I will be meeting the Supervisor again. I will explain your objections to him, since it is my duty to represent the views of the world. But it will alter nothing — I can assure you of that.”

“There is one other point,” said Wainwright slowly. “We have many objections to the Overlords — but above all we detest their secretiveness. You are the only human being who has ever spoken with Karellen, and even you have never seen him! Is it surprising that we doubt his motives?”

“Despite all that he has done for humanity?”

“Yes — despite that. I do not know which we resent more — Karellen’s omnipotence, or his secrecy. If he has nothing to hide, why will he never reveal himself? Next time you speak with the Supervisor, Mr. Stormgren, ask him that!”

Stormgren was silent. There was nothing he could say to this — nothing, at any rate, that would convince the other. He sometimes wondered if he had really convinced himself.

It was, of course, only a very small operation from their point of view, but to Earth it was the biggest thing that had ever happened. There had been no warning when the great ships came pouring out of the unknown depths of space. Countless times this day had been described in fiction, but no one had really believed that it would ever come. Now it had dawned at last; the gleaming, silent shapes hanging over every land were the symbol of a science Man could not hope to match for centuries. For six days they floated motionless above his cities, giving no hint they knew of his existence. But none was needed; not by chance alone could those mighty ships have come to rest so precisely over New York, London, Paris, Moscow, Rome, Cape Town, Tokyo, Canberra….

Even before the ending of those heart-freezing days, some men had guessed the truth. This was not the first tentative contact by a race which knew nothing of man. Within those silent, unmoving ships, master psychologists were studying humanity’s reactions. When the curve of tension had reached its peak, they would act.

And on the sixth day Karellen, Supervisor for Earth, made himself known to the world in a broadcast that blanketed every radio frequency. He spoke in English so perfect that the controversy it began was to rage across the Atlantic for a generation. But the context of the speech was more staggering even than its delivery. By any standards, it was a work of superlative genius, showing a complete and absolute mastery of human affairs. There could be no doubt that its scholarship and virtuosity, its tantalizing glimpses of knowledge still untapped were deliberately designed to convince mankind that it was in the presence of overwhelming intellectual power. When Karellen had finished, the nations of Earth knew that their days of precarious sovereignty had ended. Local, internal governments would still retain their powers, but in the wider field of international affairs the supreme decisions had passed from human hands. Arguments — protests — all were futile.

It was hardly to be expected that all the nations of the world would submit tamely to such a limitation of their powers. Yet active resistance presented baffling difficulties, for the destruction of the Overlords’ ships, even if it could be achieved, would annihilate the cities beneath them. Nevertheless, one major power had made the attempt. Perhaps those responsible hoped to kill two birds with one atomic missile, for their target was floating above the capital of an adjoining and unfriendly nation.

As the great ship’s image had expanded on the television screen in the secret control room, the little group of officers and technicians must have been torn by many emotions. If they succeeded — what action would the remaining ships take?

Could they also be destroyed, leaving humanity to go its own way once more? Or would Karellen wreak some frightful vengeance upon those who had attacked him? The screen became suddenly blank as the missile destroyed itself on impact, and the picture switched immediately to an airborne camera many miles away. In the fraction of a second that had elapsed, the fireball should already have formed and should be filling the sky with its solar flame.

Yet nothing whatsoever had happened. The great ship floated unharmed, bathed in the raw sunlight at the edge of space. Not only had the bomb failed to touch it, but no one could ever decide what had happened to the missile. Moreover, Karellen took no action against those responsible, or even indicated that he had known of the attack. He ignored them contemptuously, leaving them to worry over a vengeance that never came. It was a more effective, and more demoralizing, treatment than any punitive action could have been. The government responsible collapsed completely in mutual recrimination a few weeks later.

There had also been some passive resistance to the policy of the Overlords. Usually, Karellen had been able to deal with it by letting those concerned have their own way, until they had discovered that they were only hurting themselves by their refusal to co-operate. Only once had he taken any direct action against a recalcitrant government.

For more than a hundred years, the Republic of South Africa had been the centre of social strife. Men of good will on both sides had tried to build a bridge, but in vain — fears and prejudices were too deeply ingrained to permit any cooperation. Successive governments had differed only by the degree of their intolerance; the land was poisoned with hate and the aftermath of civil war. When it became clear that no attempt would be made to end discrimination, Karellen gave his warning. It merely named a date and time — no more. There was apprehension, but little fear or panic, for no one believed that the Overlords would take any violent or destructive action which would involve innocent and guilty alike.

Nor did they. All that happened was that as the sun passed the meridian at Cape Town — it went out. There remained visible merely a pale, purple ghost, giving no heat or light. Somehow, out in space, the light of the sun had been polarized by two crossed fields so that no radiation could pass. The area affected was five hundred kilometres across, and perfectly circular.

The demonstration lasted thirty minutes. It was sufficient: the next day the Government of South Africa announced that full civil rights would be restored to the white minority.

Apart from such isolated incidents, the human race had accepted the Overlords as part of the natural order of things. In a surprisingly short time, the initial shock had worn off, and the world went about its business again. The greatest change a suddenly awakened Rip Van Winkle would have noticed was a hushed expectancy, a mental glancing-over-the-shoulder, as mankind waited for the Overlords to show themselves and to step down from their gleaming ships. Five years later, it was still waiting. That, thought Stormgren, was the cause of all the trouble.

There was the usual circle of sightseers, cameras at the ready, as Stormgren’s car drove on to the launching-field. The Secretary-General exchanged a few final words with his assistant, collected his brief-case, and walked through the ring of spectators.

Karellen never kept him waiting for long. There was a sudden “Oh!” from the crowd, and a silver bubble expanded with breathtaking speed in the sky above. A gust of air tore at Stormgren’s clothes as the tiny ship came to rest fifty metres away, floating delicately a few centimetres above the ground, as if it feared contamination with Earth. As he walked slowly forward, Stormgren saw that familiar puckering of the seamless metallic hull, and in a moment the opening that had so baffled the world’s best scientists appeared before him. He stepped through it into the ship’s single, softly-lit room. The entrance sealed itself as if it had never been, shutting out all sound and sight.
