I’m not sure. I walked the streets. But I am still not sure among what crowds I walked.

I’ve said the Face no longer needed a voice. This is why. In the old days I suppose the Man-Machine would have said, “Come,” when it wanted us nearer. Now in effect it said, “Come”—and we came. But not on foot. Not under our own directions.

A whole segment of unnecessary, primitive activities was simply eliminated. There was no need for the clumsy human mechanisms to hear the summons, comprehend it, consider it, debate obeying, decide to comply, set muscles in motion and trudge across the plain.

Instead, the Face issued its voiceless command—and there was a sort of vortex in the red twilight air between the cliff-side and ourselves. Smoothly, gently, inexorably, we were drawn up along that spinning of the air, seeing the gray earth fall away beneath us and then slide backward with blurring swiftness. The Face grew startlingly larger, too large to see as a whole, large and near and very clear.

We lost sight of the tremendous serene brow, of the vast smooth chin, of the great downward slope of the nose, of the cheeks etched with experiences which no human and no machine could ever have known separately.

Walls of rock rushed at us, opened, sucked us in.

What did I see? I wish I could tell you. I can make useless sketches in the air with both hands, trying to show how the spiral streets sloped and how the blurred house-fronts slid past. But if I did you would picture ordinary house-fronts and a street that curved but was like any street you know. And these were too different to describe.

It may be that the street really did move with all its strange shapely houses. I have an idea that the whole interior of the city was actually in constant motion, as a machine might be, and that if motion ceased they would cease too, the city and the race of man.

But I can tell you this much. Ideas blew through that city like puffs of smoke through an industrial town. They brushed my mind and were gone, leaving only bewildering fragments in their wake. Sometimes they brushed two of us at once and we had incredible glimpses into one another’s minds wherever the idea touched, evoking mutual memories, interlocking thoughts like rings that spread in water.

De Kalb had said, long ago, that these men were gods. He was right. They were far beyond any concept the men of my day had ever dreamed of for his gods. We walked through their city, were brushed by their thoughts, breathed the air of their streets, but we never saw them.

They were there. They were all around us. I am perfectly sure of that. I didn’t see them. I didn’t feel or hear them. But I knew they were there as surely as you know the chair in which you sit now has a back upon which you are leaning, though you won’t see it unless you turn.

I had constantly the odd feeling that if I could turn I might come face to face with any man of the city I chose. But I was not capable of turning in the necessary direction, which would probably have been through a dimension we know nothing of.

I wish I could have seen them.

24. Battling the Nekron

The gusts of thought blew thicker and faster around us as we were drawn up the spiral. Our minds linked in impossible chords and discords as impossible ideas struck responses from us all.

Then the light failed us. Perhaps our sight failed us. I think we were drawn through a rather long space of solid wall, like a locked doorway which only this vortex could open for material things.

When we could see again we were in a bare and empty room. The shape of it was indescribable because of the extensions along which it reached. I was reminded a little of the corridor down which Belem had guided me toward the Subterrane of the middle future. Geometry, blindingly confused in patterns of inverted planes.

And then the room around us spoke directly, in the very air that pressed upon our minds. The Face of Ea spoke.

I had heard that voice before, if voice you could call it The Man-Machine who guarded our age-long slumbers had said, “Sleep—sleep,” in this same voice, growing deeper, calmer, less human as the eons passed. Now it was the voice and the mind of the Man-Machine but immeasurably altered, incomprehensibly more complex.

“You have seen my first beginning,” the Face of Ea said. “You and I have come together to this place at the end of our planet’s life. I have watched over your sleep for a purpose. You are my weapons now.

“The nekron can never be destroyed. But with your help it can be excised out of normal space, normal time. For that I summoned you. For that I guided your journeying in time. Think and you will understand.”

I believe the same knowledge flowed through the minds of my companions in the moment of timeless revelation that came to me. In a series of small, clear pictures I saw the manlike, killing creature that was the nekron, touching me as it swooped through oscillating time, becoming part human by the touch, running rampant through the worlds of humanity.

“Because of its release and its attacks,” the voice of Ea said, “it is part human now. You have learned to fight it. To save yourselves and us you must finish the fight. The nekron cannot be touched—except by you. But we must somehow excise it out of the universe, not only in space but in time. We must cut back through time, so that we divide and alter the past as well as the present.”

Pictures flashed again through our minds but I at least was able to understand. I saw the worlds of the galaxy turning on their axis and, more cloudily, I saw time turning also, linked to the turning worlds each by its own axis as tangible as the planets themselves to that inner vision. Very dimly I saw something that flashed a little as Belem’s severing lights had flashed when the two electronic matrices split in duplicates from the original.

“I need a wedge, a blade, to split the nekronic infection from normal space and time,” the voice went on. “You are my weapons. Do you understand the task before us?

“Belem learned the way, through the linkage of the knowledge of two eras. Now, on an infinitely larger scale, we must accomplish the same cleaving of two spheres. And each must remain equal in every way to the one original or the balance of the universe will be destroyed.

“They will differ—if we prevail—in one way only. One will be nekronic matter, one will be normal. Never in contact anywhere through all time and space. Do you understand your tasks?

“You must fight as my weapons against the nekronic universe. Together we must cleave the universe itself in two.”

If you can imagine a sharp tool made sentient, you may guess a little of how what followed seemed to us, who were so integral a part of the tremendous conflict, the ultimate destruction.

First, the voice died.

Then there was movement past me and the room seemed to slip into darkness—or was if I that moved? Those corners of non-Euclidian shape were vortices that swept us apart. We four were the component parts of an exploding nova that shot outward through space, through time. Around me I saw stars, moving very swiftly, and I was alone and there was an inexplicable changing everywhere.

I knew then that I was moving through time, not a continuous movement but an oscillation, a vibration that swung me back and forth like a pendulum through a period of a few seconds. As the nekronic being moved.

There was further motion—not my own—around me. I could see only the vibrating stars but I knew through senses without name that my companions were not far away now. Paynter was a strong harsh relentless ego within reach of my mind, though all I could see was stars beyond stars, flaring into sight as my vision penetrated farther.
