And now we reached the end of the shaft down whose sides we had come. It ended abruptly, and below on each side lay a great open space, obscured by drifting clouds of mist. But the stair did not end with the shaft. It dropped straight on down, a free, unsupported spiral of gleaming metal, winding down into the obscuring mists that hid its lower length. It was an eery thing to see, that gigantic twisted stairway, like a great corkscrew, vanishing down into the mists, like some pathway of the gods from heaven to earth. And it could hardly have been hung there by less than gods, I thought. No metal or material ever known to me would have been able thus to hold its unsupported weight in the form of this stair, yet there it was, seemingly tossed there in godlike indifference to the laws of mechanics. In its way, it was as great a wonder as the great building above. As that thought came to me, the light around us began to grow, to redden like the sunrise, and the mists cleared, drifted away in masses, vanished. And there, beneath me, lay the pit.
I can only describe that pit by saying that it was like the inside of a round, squat bottle, the neck of the bottle being the shaft down which I had come. This great cavern below me was roughly circular in shape, all of four miles in diameter, and a mile from its level floor to its glowing roof. For that roof was glowing. Looking up at it as we marched on down, I saw that set in it were scores of brilliant globes of glass, from which a flood of growing light, golden light, sunlight, daylight, was pouring down.
I saw now that the spiral stair down which we marched reached down to the pit's floor, and touched it near its center. And I saw, too, that all of the great cavern's floor, from one towering side to another, was covered with mass on mass of white, roofless buildings, of all shapes, covering the floor of the pit and huddling closely beneath the perpendicular walls of smooth rock.
At the center of this great mass of buildings, directly below us, was a great open clearing, or plaza, and it was there that the stairway touched the pit's floor. And from this plaza, clear to the circling walls, nine streets branched out, radiating in every direction like the spokes of a wheel. Along those streets moved great masses of men, and these were the dwellers in the city, the people of the pit.
So it was that I looked first on the city of the pit, the city of the Raider, and its people, over whom his shadow had been cast. And, looking, I wondered if there in the massed crowds below were Lantin and Cannell, and if it were possible to find them, here.
Again our guards ordered us forward, and we marched on. But now only a low wall on each side protected us from the abyss, and there was no wall on the right side against which to cling. But our guards seemed to mind this not at all, and I judged that they had made many trips up and down the stair, to be thus hardened to its dangers.
As we descended, Denham explained to me in a low voice the origin of the lights on the roof. These were merely lenses of a kind, he said, which diffused into the cavern real sunlight brought from above. I had already seen and puzzled at the glass globes set on pedestals through the city of cylinders above, but now saw their purpose. Those globes received the sunlight, transmitted it in some unknown fashion down to the globes on the roof, which gave it forth again. Thus it was that day and night in the pit were the same as in the world above, and the light there waxed and waned in accordance with the rising and setting of the sun which these people never saw.
We drew closer and closer toward the ground, and now I saw that at the stair's end, where it touched and debouched on the pit's floor, it was closed by a high, heavy gate of metal, barred and spiked, and that on our own side of this gate was a force of some fifty of the guards, armed with long spears and also with curious little cylinders of shining metal which they carried in their belts, and which I guessed were weapons of a kind unknown to myself.
As we came down toward them, these guards drew aside and unlocked the big gate. Our own captors unshackled us, and then pushed us through it unceremoniously, so that we stood in the clearing or plaza. And the gate was quickly shut and locked behind us.
Standing there, I forgot all else in the fascination of the scene around me. Across the open plaza, which was smoothly floored with stone, a great multitude of people were coming and going, and it was that shifting throng that held my gaze. For in it were men of every race and land and time, men of the far past and men of my own time, all seized and brought here by the Raider to mix and mingle in one vast, variegated throng. Even that first glance showed me that there must be thousands, tens of thousands of men prisoned in this gigantic under-city, and it showed me, too, that even as among the guards and slaves above, there were no women. All were comparatively young men, few being over middle age, and nearly all had the appearance of warriors.
