Around us there swarmed all the myriads of inbound ships that filled the descension-lane, drawn from every quarter of the Galaxy toward Canopus, the center and capital of our universe. Long cargo-ships from far Spica there were, laden with all the strange merchandise of that sun's circling worlds; luxurious passenger-liners from Regulus and Altair, filled with tourists eager for their first sight of great Canopus; swift little boats from the thronging suns and worlds of the great Hercules cluster; battered tramps which owned no sun as home, but cruised eternally through the Galaxy, carrying chance cargoes from star to star; and here and there among the swarms of alien ships a human-manned craft from our own distant little solar system. All these and a myriad others raced smoothly beside and around us as we shot down toward the mighty world beneath.
Swiftly, though, the traffic about us branched away and thinned as we dropped nearer to the planet's surface. Beneath the light of the immense white sun above, its landscape lay clearly revealed, a far-sweeping panorama of smoothly sloping plains and valleys, parklike in its alternation of lawn and forest. Here and there on the surface of this world sprawled its shining cities, over whose streets and towers our cruiser sped as we flashed on. Then, far ahead, a single mighty gleaming spire became visible against the distant horizon, growing as we sped on toward it into a colossal tower all of two thousand feet square at its base, and which aspired into the radiant sunlight for fully ten thousand feet. On each side of it there branched away a curving line of smaller buildings, huge enough in themselves but dwarfed to toylike dimensions by the looming grandeur of the stupendous tower. And it was down toward the smooth sward at the tower's base that our ship was slanting now, for this was the seat of the great Council of Suns itself.
Down we sped toward the mighty structure's base, down over the great buildings on either side which housed the different departments of the Galaxy's government, down until our ship had come smoothly to rest on the ground a hundred feet from the tower itself. Then the ship's hull-door was clanging open, and a moment later I had stepped onto the ground outside and was striding across the smooth sward toward the mighty tower. Through its high-arched doorway I passed, and down the tremendous corridor inside toward the huge doors at its end, which automatically slid smoothly sidewise as I approached. The next moment I had passed through them and stood in the Hall of the Council itself.
Involuntarily, as always, I paused on entering, so breath-taking was the immensity of the place. A single vast circular room, with a diameter of near two thousand feet, it covered almost all the mighty tower's first floor. From the edge of the great circle the room's floor sloped gently down toward its center, like a vast shallow bowl, and at the center stood the small black platform of the Council Chief. Out from that platform back clear to the great room's towering walls were ranged the countless rows of seats, just filling now with the great Council's thousands of members.
Beings there were among those thousands from every peopled sun in all the Galaxy's hosts, drawn here like myself each to represent his star in this great Council which ruled our universe. Creatures there were utterly weird and alien in appearance, natives of the whirling worlds of the Galaxy's farthest stars—creatures from Aldebaran, turtle-men of the amphibian races of that star; fur-covered and slow-moving beings from the planets of dying Betelgeuse; great octopus-creatures from mighty Vega; invertebrate insect-men from the races of Procyon; strange, dark-winged bat-folk from the weird worlds of Deneb; these, and a thousand others, were gathered in that vast assemblage, forms utterly different from each other physically, but able to mix and understand each other on the common plane of intelligence.
Within another moment I had passed down the broad aisle and had slipped into my own seat, and now I saw that on the black platform at the room's center there stood silent the Council Chief. A strange enough figure he made, for he was of the races of Canopus, natives of this giant star-system, a great, unhuman head with no body and with but a single staring eye, carrying himself on tiny, pipe-stem limbs. Silently he stood there, contemplating the gathering members. Within another minute all had taken their seats, and then a sudden hush swept over them as the Council Chief stepped forward and began to speak, in the tongue that has become universal throughout the Galaxy, his strange, high voice carried to every end of the vast room by the great amplifiers which make every whisper in it clearly heard.
"Members of the Council," he said, "I have called this meeting, have summoned you here to Canopus, each from his native star, because I have to place before you a matter of the utmost importance. I have summoned you here because there has risen to face us the most vital problem that has yet confronted us in our government of the Galaxy—the greatest and most terrible danger, in fact, that has ever threatened our universe!
"Other dangers, other problems, have faced us in the past, and all these we have overcome, by massing all our knowledge and science, have ruled with more and more power over the inanimate matter of our universe, our Galaxy. We have saved planets and their peoples from extinction, by shifting them from dying old suns to flaming new ones. We have succeeded in breaking up and annihilating some of the great comets whose headlong flights were carrying destruction across the Galaxy. We have even dared to change the course of suns, to prevent collisions between them that would have annihilated their circling worlds. It might seem, indeed, that we, the massed peoples of the Galaxy, have risen to such power that all things in it are subject to our will, obedient to our commands. But we have not. One thing alone in the Galaxy remains beyond our power to change or alter, one thing beside which all our power and our science are as nothing. And that is the nebula.
"A nebula is the vastest thing in all our universe, and the most mysterious. A gigantic mass of glowing gas that stretches across countless billions of miles of space, its mighty bulk flames in the heavens like a universe of fire. Beside its vast dimensions all the suns of the Galaxy are but as sparks beside a great, consuming blaze. Here and there in our Galaxy lie these mighty mysteries, these flaming nebulæ, and mightiest of all is that one which we call the Orion Nebula, that gigantic globe of flaming gas which measures light-years in diameter, burning in giant splendor at the Galaxy's heart. We know that the great nebula is growing slowly smaller, that through the eons it contracts to form new blazing stars, but what its constitution may be, what mysteries it may hide, has never been known, since it would be annihilation for any ship to approach too near to its fiery splendor, and all our interstellar traffic has detoured always far around its flaming mass. Because of that inaccessibility no large attention has ever been paid to the great nebula, nor would there be now, had not something been discovered but now by our scientists regarding it which seems to herald the end of our universe.
