Twenty-four hours after our start I stood again in the bridgeroom, alone except for the silent, imperturbable figure of my ever-watchful wheelman, Nal Jak, staring out with him into the black gulf that lay before us. Many an hour we had stood side by side thus, scanning the interstellar spaces from our cruiser's bridgeroom, but never yet had my eyes been confronted by such a lightless void as lay before me now.
Our ship, indeed, seemed to be racing through a region where light was all but non-existent, a darkness inconceivable to anyone who had never experienced it. Behind lay the Galaxy we had left, a great swarm of shining points of light, contracting slowly as we sped away from it. Toward our right, too, several misty little patches of light glowed faintly in the darkness, hardly to be seen; though these, I knew, were other galaxies or star-clusters like our own-titanic conglomerations of thronging suns dimmed to those tiny flickers of light by the inconceivable depths of space which separated them from ourselves.
Except for these, though, we fled on through a cosmic gloom that was soul-shaking in its deepness and extent, an infinite darkness and stillness in which our ship seemed the only moving thing. Behind us, I knew, the formation of our fifty ships was following close on our track, each ship separated from the next by a five hundred mile interval and each flashing on at exactly the same speed as ourselves. But though we knew they followed, our fifty cruisers were naturally quite invisible to us, and as I gazed now into the tenebrous void ahead the loneliness of our position was overpowering.
Abruptly the door behind me snapped open, and I half turned toward it as Hurus Hol entered. He glanced at our speed-dials and his brows arched in surprise.
"Good enough," he commented. "If the rest of our ships can hold this pace it will bring us to the dark star in six days."
I nodded, gazing thoughtfully ahead. "Perhaps sooner," I estimated. "The dark star is coming toward us at a tremendous velocity, remember. You will notice on the telechart-"
Together we stepped over to the big telechart, a great rectangular plate of smoothly burnished silvery metal which hung at the bridgeroom's end-wall, the one indispensable aid to interstellar navigation. Upon it were accurately reproduced, by means of projected and reflected rays, the positions and progress of all heavenly bodies near the ship.
Intently we contemplated it now. At the rectangle's lower edge there gleamed on the smooth metal a score or more of little circles of glowing light, of varying sizes, representing the suns of the edge of the Galaxy behind us. Outermost of these glowed the light-disk that was our own sun, and around this Hurus Hol had drawn a shining line or circle lying more than four billion miles from our sun, on the chart. He had computed that if the approaching dark star came closer than that to our sun its mighty gravitational attraction would inevitably draw the latter out with it into space; so the shining line represented, for us, the danger line. And creeping down toward that line and toward our sun, farther up on the blank metal of the great chart, there moved a single giant circle of deepest black, an ebon disk a hundred times the diameter of our glowing little sun-circle, which was sweeping down toward the Galaxy's edge in a great curve.
Hurus Hol gazed thoughtfully at the sinister dark disk, and then shook his head. "There's something very strange about that dark star," he said, slowly. "That curving path it's moving in is contrary to all the laws of celestial mechanics. I wonder if-"
Before he could finish, the words were broken off in his mouth. For at that moment there came a terrific shock, our ship dipped and reeled crazily, and then was whirling blindly about as though caught and shaken by a giant hand. Dal Nara, the pilot, Hurus Hol and I were slammed violently down toward the bridgeroom's end with the first crash, and then I clung desperately to the edge of a switch-board as we spun dizzily about. I had a flashing glimpse, through the windows, of our fifty cruisers whirling blindly about like wind-tossed straws, and in another glimpse saw two of them caught and slammed together, both ships smashing like eggshells beneath the terrific impact, their crews instantly annihilated. Then, as our own ship dipped crazily downward again, I saw Hurus Hol creeping across the floor toward the controls, and in a moment I had slid down beside him. Another instant and we had our hands on the levers, and were slowly pulling them back into position.
Caught and buffeted still by the terrific forces outside, our cruiser slowly steadied to an even keel and then leapt suddenly forward again, the forces that held us seeming to lessen swiftly as we flashed on. There came a harsh, grating sound that brought my heart to my throat as one of the cruisers was hurled past us, grazing us, and then abruptly the mighty grip that held us had suddenly disappeared and we were humming on through the same stillness and silence as before.
I slowed our flight, then, until we hung motionless, and then we gazed wildly at each other, bruised and panting. Before we could give utterance to the exclamations on our lips, though, the door snapped open and Dal Nara burst into the bridgeroom, bleeding from a cut on her forehead. "What was that?" she cried, raising a trembling hand to her head. "It caught us there like toys-and the other ships-"
Before any of us could answer her a bell beside me rang sharply and from the diaphragm beneath it came the voice of our message-operator.
"Ships 37, 12, 19 and 44 reported destroyed by collisions, sir," he announced, his own voice tremulous. "The others report that they are again taking up formation behind us."
"Very well," I replied. "Order them to start again in three minutes, on Number One speed-scale."
As I turned back from the instrument I drew a deep breath. "Four ships destroyed in less than a minute," I said. "And by what?"
"By a whirlpool of ether-currents, undoubtedly," said Hurus Hol. We stared at him blankly, and he threw out a hand in quick explanation. "You know that there are currents in the ether-that was discovered ages ago-and that those currents in the Galaxy have always been found to be comparatively slow and sluggish, but out here in empty space there must be currents of gigantic size and speed, and apparently we stumbled directly into a great whirlpool or maelstrom of them. We were fortunate to lose but four ships," he added soberly.
I shook my head. "I've sailed from Sirius to Rigel," I said, "and I never met anything like that. If we meet another-" The strangeness of our experience, in fact, had unnerved me, for even after we had tended to our bruises and were again racing on through the void, it was with a new fearfulness that I gazed ahead. At any moment, I knew, we might plunge directly into some similar or even larger maelstrom of ether-currents, yet there was no way by which we could avoid the danger. We must drive blindly ahead at full speed and trust to luck to bring us through, and now I began to understand what perils lay between us and our destination.
As hour followed hour, though, my fearfulness gradually lessened, for we encountered no more of the dread maelstroms in our onward flight. Yet as we hummed on and on and on, a new anxiety came to trouble me, for with the passing of each day we were putting behind us billions of miles of space, and were flashing nearer and nearer toward the mighty dark star that was our goal. And even as we fled on we could see, on the great telechart, the dark disk creeping down to meet us, thundering on toward the Galaxy from which, unless we succeeded, it would steal a star.
Unless we succeeded! But could we succeed? Was there any force in the universe that could turn aside this oncoming dark giant in time to prevent the theft of our sun? More and more, as we sped on, there grew in my mind doubt as to our chance of success. We had gone forth on a blind, desperate venture, on a last slender chance, and now at last I began to see how slender indeed was that chance. Dal Nara felt it, too, and even Hurus Hol, I think, but we spoke no word to each other of our thoughts, standing for hours on end in the bridgeroom together, and gazing silently and broodingly out into the darkness where lay our goal.
* * *
On the sixth day of our flight we computed, by means of our telechart and flight-log, that we were within less than a billion miles of the great dark star ahead, and had slackened our speed until we were barely creeping forward, attempting to locate our goal in the dense, unchanged darkness ahead.
Straining against the windows, we three gazed eagerly forward, while beside me Nal Jak, the wheelman, silently regulated the ship's speed to my orders. Minutes passed while we sped on, and still there lay before us only the deep darkness. Could it be that we had missed our way, that our calculations had been wrong? Could it be-and then the wild speculations that had begun to rise in my mind were cut short by a low exclamation from Dal Nara, beside me. Mutely she pointed ahead.
At first I could see nothing, and then slowly became aware of a feeble glow of light in the heavens ahead, an area of strange, subdued light which stretched across the whole sky, it seemed, yet which was so dim as to be hardly visible to our straining eyes. But swiftly, as we watched it, it intensified, strengthened, taking shape as a mighty circle of pale luminescence which filled almost all the heavens ahead. I gave a low-voiced order to the pilot which reduced our speed still further, but even so the light grew visibly stronger as we sped on.
"Light!" whispered Hurus Hol. "Light on a dark star! It's impossible-and yet-"
And now, in obedience to another order, our ship began to slant sharply up toward the mighty circle's upper limb, followed by the half-hundred ships behind us. And as we lifted higher and higher the circle changed before our eyes into a sphere-a tremendous, faintly glowing sphere of size inconceivable, filling the heavens with its vast bulk, feebly luminous like the ghost of some mighty sun, rushing through space to meet us as we sped up and over it. And now at last we were over it, sweeping above it with our little fleet at a height of a half-million miles, contemplating in awed silence the titanic dimensions of the faint-glowing sphere beneath us. For in spite of our great height above it, the vast globe stretched from horizon to horizon beneath us, a single smooth, vastly curving surface, shining with the dim, unfamiliar light whose source we could not guess. It was not the light of fire, or glowing gases, for the sun below was truly a dead one, vast in size as it was. It was a cold light, a faint but steady phosphorescence like no other light I had ever seen, a feeble white glow which stretched from horizon to horizon of the mighty world beneath. Dumfoundedly we stared down toward it, and then, at a signal to the pilot, our ship began to drop smoothly downward, trailed by our forty-odd followers behind. Down, down, we sped, slower and slower, until we suddenly started as there came from outside the ship a highpitched hissing shriek.
"Air!" I cried. "This dark star has an atmosphere! And that light upon it-see!" And I flung a pointing hand toward the surface of the giant world below. For as we dropped swiftly down toward that world we saw at last that the faint light which illuminated it was not artificial light, or reflected light, but light inherent in itself, since all the surface of the mighty sphere glowed with the same phosphorescent light, its plains and hills and valleys alike feebly luminous, with the soft, dim luminosity of radio-active minerals. A shining world, a world glowing eternally with cold white light, a luminous, titanic sphere that rushed through the darkness of infinite space like some pale gigantic moon. And upon the surface of the glowing plains beneath us rose dense and twisted masses of dark leafless vegetation, distorted tree-growths and tangles of low shrubs that were all of deepest black in color, springing out of that glowing soil and twisting blackly and grotesquely above its feeble light, stretching away over plain and hill and valley like the monstrous landscape of some undreamed-of hell!
And now, as our ship slanted down across the surface of the glowing sphere, there gleamed ahead a deepening of that glow, a concentration of that feeble light which grew stronger as we raced on toward it. And it was a city! A city whose mighty buildings were each a truncated pyramid in shape, towering into the air for thousands upon thousands of feet, a city whose every building and street and square glowed with the same faint white light as the ground upon which they stood, a metropolis out of nightmare, the darkness of which was dispelled only by the light of its own great glowing structures and streets. Far away stretched the mass of these structures, a luminous mass which covered square mile upon square mile of the surface of this glowing world, and far beyond them there lifted into the dusky air the shining towers and pyramids of still other cities.
We straightened, trembling, turning toward each other with white faces. And then, before any could speak, Dal Nara had whirled to the window and uttered a hoarse shout. "Look!" she cried, and pointed down and outward toward the titanic, glowing buildings of the city ahead; for from their truncated summits were rising suddenly a swarm of long black shapes, a horde of long black cones which were racing straight up toward us.
I shouted an order to the pilot, and instantly our ship was turning and slanting sharply upward, while around us our cruisers sped up with us. Then, from beneath, there sped up toward us a shining little cylinder of metal which struck a cruiser racing beside our own. It exploded instantly into a great flare of blinding light, enveloping the cruiser it had struck, and then the light had vanished, while with it had vanished the ship it had enveloped. And from the cones beneath and beyond there leapt toward us other of the metal cylinders, striking our ships now by the dozens, flaring and vanishing with them in great, silent explosions of light.
"Etheric bombs!" I cried. "And our ship is the only battle-cruiser-the rest have no weapons!"
I turned, cried another order, and in obedience to it our own cruiser halted suddenly and then dipped downward, racing straight into the ascending swarm of attacking cones. Down we flashed, down, down, and toward us sprang a score of the metal cylinders, grazing along our sides. And then, from the sides of our own downward-swooping ship there sprang out brilliant shafts of green light, the deadly de-cohesion ray of the ships of the Federation Fleet. It struck a score of the cones beneath and they flamed with green light for an instant and then flew into pieces, spilling downward in a great shower of tiny fragments as the cohesion of their particles was destroyed by the deadly ray. And now our cruiser had crashed down through the swarm of them and was driving down toward the luminous plain below, then turning and racing sharply upward again while from all the air around us the black cones swarmed to the attack.
Up, up, we sped, and now I saw that our blow had been struck in vain, for the last of our ships above were vanishing beneath the flares of the etheric bombs. One only of our cruisers remained, racing up toward the zenith in headlong flight with a score of the great cones in hot pursuit. A moment only I glimpsed this, and then we had turned once more and were again diving down upon the attacking cones, while all around us the etheric bombs filled the air with the silent, exploding flares. Again as we swooped downward our green rays cut paths of annihilation across the swarming cones beneath; and then I heard a cry from Hurus Hol, whirled to the window and glimpsed above us a single great cone that was diving headlong down toward us in a resistless, ramming swoop. I shouted to the pilot, sprang to the controls, but was too late to ward off that deadly blow. There was a great crash at the rear of our cruiser; it spun dizzily for a moment in midair, and then was tumbling crazily downward like a falling stone toward the glowing plain a score of miles below.
