Except for these few incidents, though, our days were monotonous and changeless, days in which the care of the generators and the alternate watches in the conning-tower were our only occupations. And a strange stillness had seized us as we fled onward, a brooding silence that fastened itself upon my friends even as upon myself. Something from the vast, eternal silence through which we moved, some quality out of those trackless infinities of space, seemed to have entered into our inmost souls. We went about our duties like men in a dream. And dreamlike our life had become to us, I think, and still more remote and unreal and dreamlike had become the life of the eight worlds that lay so far behind us.
I had forgotten, almost, the mission upon which we sped, and through the long watches in the conning-tower my eyes followed the steady largening of the red sun ahead with curiosity only. Day by day its fiery disk was creeping farther across the heavens, until at last everything in the cruiser was drenched by the crimson, bloodlike light that streamed in through our sunward windows. Then, at last, my mind came back to consideration of the work that lay before us, for over thirty days of our journey had passed and there remained less than a hundred billion miles between Alto and ourselves.
I gave orders to slow our progress, then, and at a somewhat slackened speed our cruiser began to slant up above the plane of the great sun, for it was my plan to gain a position millions of miles directly above the star and then hover there, accompanying it on its race through space and using the powerful little telescopic windows in the conning-tower for our first observations. So through the next two days the giant sun, a single great sea of crimson fire to our eyes, crept steadily downward across the skies as we slanted over it. Our outside instruments showed us that its heat was many times less than that of our own sun, for this was a dying star. Even so it was necessary to slide special light-repelling shields over all our windows, so blinding was the star's glare.
On the fortieth day of our journey we had reached our goal. Gathered in the conning-tower, Sarto Sen, Hal Kur and I gazed down through its circular, periscopic under-window at the mighty star beneath. We had reached a spot approximately twenty million miles above the sun and had turned our course, so that we now raced above it at a speed that matched its own, like a fly hovering over a world. Below us there lay only a single vast ocean of crimson flame, that reached almost from horizon to horizon, all but filling the heavens beneath us. It was in an awed silence that we gazed down into this tremendous sea of fire, knowing as we did that only the power of the ship's generators kept it from plunging downward.
"And we are expected to investigate-that!" said Hal Kur, gazing down into the hell of flame below. "They talk of turning that aside!"
I looked at him, hopelessly. Then, before I could speak, there came a sudden exclamation from Sarto Sen, and he beckoned me to his side. He had been staring out through one of the powerful little telescopic windows set in the conning-tower's wall, and as I reached him he pointed eagerly through it, out beyond the rim of the fiery sun beneath. I gazed in that direction, straining my eyes against the glare, and then glimpsed the thing that had attracted his attention. It was a little spot of dun-colored light lying beyond the crimson sun, a buff-colored little ball that hung steady behind the great sun at a distance of perhaps a hundred million miles and that accompanied it on its flight through space.
"A planet!" I whispered, and he nodded. Then Hal Kur, who had joined us, extended his hand too, with a muttered exclamation, and there, thrice the distance of the first from Alto, there hung another and smaller ball. In a few minutes, using the powerful inset glasses, we had discovered no less than thirteen worlds that spun about the sun beneath us and that accompanied it on its tremendous journey through space. Most seemed to revolve in orbits that were billions of miles from their parent sun, and none of the others was as large as that inmost planet which we had first discovered. It was toward this largest world that we finally decided to head first; so with Sarto Sen at the controls we slanted down again from our position over the great sun, arrowing down at reduced speed toward the inmost world.
Its color was changing from buff to pale red as we neared it, and its apparent size was increasing with tremendous speed as our craft shot down toward it. Gradually, though, Sarto Sen decreased our velocity until by the time we reached an altitude of a few hundred miles above this world our ship was moving very slowly. And now, from outside, came a thin shrieking of wind, a mounting roar that told us plainly that we were speeding through air again, and that this world had at least an atmosphere. None of us remarked on that, though, all our attention being held by the scene below.
Drenched in the crimson light of the sun behind us, it was a crimson world that lay beneath us, a lurid world whose mountains, plains and valleys were all of the same bloodlike hue as the light that fell upon them, whose very lakes and rivers gave back to the sky the scarlet tinge that pervaded all things here. And as our cruiser swept lower we saw, too, that the redness of the planet beneath was no mere illusion of the crimson sunlight but inherent in itself, since all of the vegetation below, grassy plains and tangled shrubs and stunted, unfamiliar trees, were of that same red tinge that was the color-keynote of this world.
Strange and weird as it appeared, though, there seemed no sign of life on the broad plains and barren hills beneath us, and abruptly Sarto Sen headed the ship across the planet's face, speeding low over its surface while we scanned intently the panorama that unrolled beneath us. For minutes our straining scrutiny was unrewarded; and then, far ahead, a colossal shape loomed vaguely through the dusky crimson light, taking form, as we sped on toward it, as a tremendous, soaring tower. And involuntarily we gasped as our eyes took in the hugeness of its dimensions. It consisted of four slender black columns, each less than fifty feet in thickness, which rose from the ground at points a half-mile separated, four mighty pillars which slanted up into the crimson sunlight for fully ten thousand feet, meeting and merging at that distance above the ground and combining to support a circular platform, and on it we could see the shapes of what appeared to be machines, and other shapes that moved about them, though whether these last were human or not could not be distinguished from our height. And then, as my gaze fell toward the mighty tower's base, my cry brought the eyes of the others to follow my pointing finger. For gathered beneath and around the tower and extending away into the surrounding country were the massed buildings of a city. Low and flat-roofed and utterly strange in appearance were those buildings, and the narrow streets that pierced their huddled masses were all of the same smooth blackness as the tower itself-black, deep black, the roofs and streets and walls, laced with crimson parks and gardens that lay against their blackness like splashes of blood. And looming over all, its four tremendous columns rearing themselves above the streets and roofs and gardens like the limbs of a bestriding giant, the mighty tower soared into the crimson sunlight.
Sarto Sen flung an arm down toward the tower's platform, beneath us, and toward the shapes that moved on that platform. "Inhabited!" he cried. "You see? And that means that Alto's change in course was-"
He broke off; uttered a smothered cry. A spark of intense white light had suddenly broken into being on the platform beneath us, a beam of blinding light that stabbed straight up toward us, bathing the cruiser in its unearthly glow. And suddenly our ship was falling!
