Astounding Stories of Super-Science, November, 1930

"How do you suppose we'll make ourselves understood to the people of Europa?" asked Carr, when they had swung around the great orb of Jupiter and were headed toward the satellite.

"Shouldn't have any trouble, Carr. Believe me, to a people who have progressed to the point of sending mental messages over five hundred miles of space, it'll be a cinch, understanding our simple mental processes. Bet they'll read our every thought."

"That's right. But the language. Proper names and all that. Can't get those over with thought waves."

"No, but I'll bet they'll have some way of solving that too. You wait and see."

Carr lighted a cigar and inhaled deeply as he gazed from one of the ports. He'd never felt better in his life. Always had liked Martian tobacco, too. Wondered what they'd do when the supply ran out. One thing they couldn't produce synthetically. The disc of the satellite loomed near and it shone with a warmly inviting light. Almost red, like the color of Mars, it was. Sort of golden, rather. Anyway, he wondered what awaited them there. This was a great life, this roaming in space, unhampered by laws or conventions. The Nomad was well named.

"Wonder what they'll think of our yarn," he said.

"And me. I wonder, too, what that ungodly thing was back there. The thing that is now the grave of some of their people. And what the golden sphere was doing so far from home. It's a mystery."

They had gone over the same ground a hundred times and had not reached a satisfactory conclusion. But perhaps they'd learn more in the city of golden domes.

"Another thing," said Carr, "that's puzzled me. Why is it that Europa has not been discovered before this; that it's inhabited, I mean?"

"Rocket ships couldn't carry enough fuel. Besides, our astronomers've always told us that the outer planets were too cold; too far from the sun."

"That is something to think about. Maybe we'll not be able to stand the low temperature; thin atmosphere; low surface gravity."

"We've our insulated suits and the oxygen helmets for the first two objections. The G-rays'll hold us down in any gravity. But we'll see mighty soon. We're here."

They had entered the atmosphere as they talked and the Nomad was approaching the surface in a long glide with repulsion full on. It was daytime on the side they neared. Pale daylight, but revealing. The great ball that was Jupiter hung low on the horizon, its misty outline faintly visible against the deep green of the sky.

_______________________

The surface over which they skimmed was patchworked with farm-lands and crisscrossed by gleaming ribbons. Roadways! It was like the voice-vision records of the ancient days on Mars and Terra before their peoples had taken to the air. Here was a body where a person could get out in the open; next to nature. They crossed a lake of calm green water fringed by golden sands. At its far side a village spread out beneath them and was gone; a village of broad pavements and circular dwellings with flat rooms, each with its square of ground. A golden, mountain range loomed in the background; vanished beneath them. More fields and roads. Everywhere there were yellows and reds and the silver sheen of the roads. No green save that of the darkening sky and the waters of the streams and ponds. It was a most inviting panorama.

Occasionally they passed a vessel of the air – strange flapping-winged craft that soared and darted like huge birds. Once one of them approached so closely they could see its occupants, seemingly a people similar to the Venusians, small of stature and slender.

"How in time are we to find this city of golden domes?" Carr ejaculated.

As if in answer to his question there came a startling command, another of the mental messages.

"Halt!" it conveyed to their mind. "Continue not into our country until we have communed with you."

Obediently Mado brought up the nose of the Nomad and slowed her down to a gradual stop. They hovered at an altitude of about four thousand feet, both straining their ears as if listening for actual speech.

"It is well," continued the message. "Your thoughts are good. You come from afar seeking the city of golden domes. Proceed now and a fleet of our vessels will meet you and guide you to our city."

"Now wouldn't that jar you?" whispered Carr. "Just try to get away with anything on this world."

Mado laughed as he started the generators of the propelling energy. "I'd hate to have a wife of Europa," he commented. "No sitting-up-with-sick-friend story could get by with her!"

CHAPTER V

The City of Golden Domes

With the Nomad cruising slowly over the surface of the peaceful satellite, Mado sampled the atmosphere through a tube which was provided for that purpose. The pressure was low, as they had expected; about twenty inches of mercury in the altitude at which they drifted. But the oxygen content was fairly high and the impurities negligible. A strange element was somewhat in evidence, though Mado's analysis showed this to be present in but minute quantity. They opened the ports and drew their first breath of the atmosphere of Europa.

"Good air, Carr." Mado was sniffing at one of the ports. "A bit rare for you, but I think you'll get along with it. Temperature of forty-five degrees. That's not so bad. The strangest thing is the gravity. This body isn't much more than two thousand miles in diameter, yet its gravity is about the same as on Venus – seven eighths of that of Terra. Must have a huge nickel-iron core."

"Yes. It'll be a cinch for me. But you, you big lummox – it's the G-ray for you as long as we're here."

"Uh-huh. You get all the breaks, don't you?"

Carr laughed. He was becoming anxious to land. "What sort of a reception do you suppose we'll get?" he said.

"Not bad, from the tone of that last message. And here they come, Carr. Look – a dozen of them. A royal reception, so far."

Suddenly they were in the midst of a flock of great birds; birds that flapped their golden wings to rise, then soared and circled like the gulls of the terrestrial oceans. And these mechanical birds were fast. Carr and Mado watched in fascination as they strung out in V formation and led the way in the direction of the setting sun. Six, seven hundred miles an hour the Nomad's indicator showed, as they swung in behind these ships of Europa.

_______________________

They crossed a large body of water, a lake of fully five hundred miles in width. More country then, hardly populated now and with but few of the gleaming roadways. The sun had set, but there was scarcely any diminution of the light for the great ball that was Jupiter reflected a brilliance of far greater intensity than that of the full Moon on a clear Terrestrial night. A marvelous sight the gigantic body presented, with its alternate belts of gray-blue and red and dazzling white. And it hung so low and huge in the heavens that it seemed one had but to stretch forth a hand to touch its bright surface.

Another mountain range loomed close and was gone. On its far side there stretched the desolate wastes of a desert, a barren plain that extended in all directions to the horizon. Wind-swept, it was and menacing beneath them. Europa was not all as they had first seen it.

A glimmer of brightness appeared at the horizon. The fleet was reducing speed and soon they saw that their journey was nearly over. At the far edge of the desert the bright spot resolved itself into the outlines of a city, the city of golden domes. Cones they looked like, rather, with rounded tops and fluted walls. The mental message had conveyed the most fitting description possible without words or picture.

The landing was over so quickly that they had but confused impressions of their reception. A great square in the heart of the city, crowded with people. Swooping maneuvers of hundreds of the bird-like ships. An open space for their arrival. The platform where a committee awaited them. The king, or at least he seemed to be king. The sea of upturned faces, staring eyes.

_______________________

Mado fidgeted and opened his mouth to voice a protest but Carr nudged him into silence. The king had risen from his seat in the circle on the platform and was about to address them. There was no repetition of the telepathic means of communication.

"Welcome, travelers from the inner planets," said the king. He spoke Cos perfectly! "Cardos, emperor of the body you call Europa, salutes you. Our scientists have recorded your thoughts with their psycho-ray apparatus and have learned that you have a message for us, a message we fear is not pleasant. Am I correct?"

Carr stared at the soft-voiced monarch of this remarkable land. It was incredible that he spoke in the universal language of the inner planets!

"Your Highness," he replied, "is correct. We have a message. But it amazes us that you are familiar with our language."

"That we shall explain later. Meanwhile – the message!"

"The message," Carr said, "is not pleasant. A golden sphere out in space. Helpless in the clutches of a nameless monster, a vast creature of jellylike substance but possessed of enormous destructive energy. A mental message to our vessel warning us away and bidding us to come here; to tell you of their fate. We escaped and here we are."

The face of Cardos paled. He reached for an egg-shaped crystal that reposed on the table; spoke rapidly into its shimmering depths. Hidden amplifiers carried his voice throughout the square in booming tones. It was a strange tongue he spoke, with many gutturals and sibilants. A groan came up from the assembled multitude.

Cardos tossed the crystal to the table with a resigned gesture, then tottered and swayed. Instant confusion reigned in the square and the emperor was assisted from the platform by two of his retainers. They never saw him again.

_______________________

One of the counsellors, a middle-aged man with graying russet hair and large gray eyes set in a perfectly smooth countenance, stepped from the platform and grasped the two adventurers as the confusion in the square increased to an uproar.

"Come," he whispered, in excellent Cos; "I'll explain all to you in the quiet of my own apartments. I am Detis, a scientist, and my home is close by."

Gently he clung to them as the larger men forced their way between the milling groups of excited Europans. No one gave them much attention. All seemed to be overcome with grief. A terrible disaster, this loss of the golden sphere must be!

They were out of the square and in one of the broad streets. The fluted sides of the unpointed cones shone softly golden on all sides. Alike in every respect were these dwellings of the people of Europa, and strangely attractive in the light of the mother planet.

Not a word was spoken when they reached the abode of their guide. They entered an elaborate hall and were whisked upward in an automatic elevator. Detis ushered them into his apartment when they alighted. He smiled gravely at their looks of wonder as they cast eyes on the maze of apparatus before them. It was a laboratory rather than a living room in which they stood.

Detis led them to an adjoining room where he bid them be seated. They exchanged wondering glances as their host paced the floor vigorously before speaking further.

"Friends," he finally blurted, "I hope you'll excuse my emotion but the news you brought is a terrible blow to me as to all Europa. Carli, our prince, beloved son of Cardos, was commander of the ship you reported lost. We deeply mourn his loss."

_______________________

Carr and Mado waited in respectful silence while their host made effort to control his feelings.

"Now," he said, after a moment, "I can talk. You have many questions to ask, I know. So have I. But first I must tell you that Carli's was an expedition to your own worlds. A grave danger hangs over them and he was sent to warn them. He has been lost. Our only space-ship capable of making the journey also is lost. Six Martian years were required to build it, so I fear the warning will never reach your people. Already the time draws near."

"A grave danger?" asked Mado. "What sort of a danger?"

"War! Utter destruction! Conquest by the most warlike and ambitious people in the solar system."

"Not the people of Europa?" asked Carr.

"Indeed not. There is another inhabited satellite of Jupiter, next farthest from the mother planet. Ganymede, you call it. It is from there that these conquerors are to set forth."

"Many of them?" inquired Mado.

"Two million or so. They're prepared to send an army of more than a tenth of that number on the first expedition."

"A mere handful!" Carr was contemptuous.

"True, but they are armed with the most terrible of weapons. Your people are utterly unprepared and, unless warned, will be driven from their cities and left in the deserts to perish of hunger and exposure. This is a real danger."

"Something in it, Carr, if what he says is true. We've no arms nor warriors. Haven't had for two centuries. You know it as well as I do."

"Bah! Overnight we could have a million armed and ready to fight them off."

_______________________

Detis raised his hand. "You offend me," he said gravely. "I have told you this in good faith and you reward me with disbelief and boastful talk. Your enemies are more powerful than you think, and your own people utterly defenceless against them."

"I'm sorry," Carr apologized, "and I'll listen to all you have to say. Surely your prince has not given his life in vain." He was ashamed before this scientist of Europa.

A tinkling feminine voice from the next room called something in the Europan tongue.

Detis raised his head proudly and his frown softened at the sound of dainty footsteps. His voice was a caress as he replied.

A vision of feminine loveliness stood framed in the doorway and the visitors rose hastily from their seats. Carr gazed into eyes of the deepest blue he had ever seen. Small in stature though this girl of Europa was – not more than five feet tall – she had the form of a goddess and the face of an angel. He was flushing to the roots of his hair. Could feel it spread. What an ass he was anyway! Anyone'd think he'd never seen a woman in all his thirty-five years!

"My daughter, Ora, gentlemen," said Detis.

The girl's eyes had widened as she looked at the huge Martian with the funny black box on his back. They dropped demurely when turned to those of the handsome Terrestrial.

"Oh," she said, in Cos, "I didn't know you had callers."

CHAPTER VI

Vlor-urdin

The time passed quickly in Pala-dar, city of the golden domes. Detis spent many hours in the laboratory with his two visitors and the fair Ora was usually at his side. She was an efficient helper to her father and a gracious hostess to the guests.

The amazement of the visitors grew apace as the wonders of Europan science were revealed to them. They sat by the hour at the illuminated screen of the rulden, that remarkable astronomical instrument which brought the surfaces of distant celestial bodies within a few feet of their eyes, and the sounds of the streets and the jungles to their ears. It was no longer a mystery how the language of Cos had become so familiar to these people.

They learned of the origin of the races that inhabited Europa and Ganymede. Ages before, it was necessary for the peoples of the then thickly populated Jupiter to cast about for new homes due to the cooling of the surface of that planet. Life was becoming unbearable. In those days there were two dominant races on the mother body, a gentle and peaceful people of great scientific accomplishment and a race of savage brutes who, while very clever with their hands, were of lesser mental strength and of a quarrelsome and fighting disposition.

Toward the last the population of both main countries was reduced to but a few survivors, and the intelligent race had discovered a means of traversing space and was prepared to leave the planet for the more livable satellite – Europa. Learning of these plans, the others made a treaty of perpetual peace as a price for their passage to another satellite – Ganymede. The migration began and the two satellites were settled by the separate bands of pioneers and their new lives begun.

_______________________

The perpetual treaty had not been broken since, but the energies of the warlike descendants of those first settlers of Ganymede were expended in casting about for new fields to conquer. Through the ages they cast increasingly covetous eyes on those inner planets, Mars, Terra and Venus. Not having the advantage of the Rulden, they knew of these bodies only what could be seen through their own crude optical instruments and what they had learned by word of mouth from certain renegade Europans they were able to bribe.

While their neighbors of the smaller satellite were engaged in peaceful pursuits, tilling the soil and making excellent homes for themselves, the dwellers on Ganymede were fashioning instruments of warfare and building a fleet of space-ships to carry them to their intended victims. It was a religion with them; they could think of nothing else. An unscrupulous scientist of Europa sold himself to them several generations previously and it was this scientist who had made the plans for their space-fliers and had contrived the deadly weapons with which they were armed. He likewise taught them the language of Cos and it now was spoken universally throughout Ganymede in anticipation of the glorious days of conquest.

"You honestly believe them able to do this?" asked Carr, still skeptical after two days of discussion.

"I know it as a certainty," Detis replied solemnly. "It is only during the past generation we have learned of the completeness and awfulness of their preparations. Your people can not combat their sound-ray. With it they can remain outside the vision of those on the surface and set the tall buildings of your cities in harmonic vibrations that will bring them down in ruins about the ears of the populace."

_______________________

"There'll be nothing left for them to take if they destroy all our cities: nowhere for them to live. I don't get it."

"Only a few will be destroyed completely, to terrify the rest of the inhabitants of your worlds. Others will be depopulated by means of vibrations that will kill off the citizens without harming the cities themselves – vibrations which are capable of blanketing a large area and raising the body temperature of all living things therein to a point where death will ensue in a very few minutes. Other vibrations will paralyze all electrical equipment on the planet and make it impossible for your ships of the air to set out to give battle, even were they properly armed."

"Looks bad, Carr," said Mado glumly.

"It does that. We've got to go back and carry the warning."

"I fear it is too late," said Detis. "Much time will be needed in which to develop a defense and surely it can not be done within the three isini before they set forth – about four of your days."

"They leave that soon?" Carr was taken aback.

"Yes, with their one hundred and twenty vessels; forty to each of your three planets; seventeen hundred men to a vessel."

Carr jumped to his feet. "By the heat devils of Mercury!" he roared, "well go to their lousy little satellite and find a way to prevent it!"

_______________________

Ora gazed at his flushed face with unconcealed admiration.

"You're crazy!" exploded Mado. "What can we do with the Nomad?"

"Her D-ray can do plenty of damage."

"Yes, but they'd have us down before we could account for five of their vessels. It's no use, I tell you."

But Carr was stubborn. "We'll pay them a call anyway. I'll bet we can dope out some way of putting it over on them. Are you game?"

"Of course I'm game. I'll go anywhere you will. But it's a fool idea just the same."

"Maybe so. Maybe not. Anyway – let's go."

"Just a moment, gentlemen," Detis interposed. "How about me?"

Carr stared at him and saw that his eyes shone with excitement. "Why, I believe you'd like to go with us!" he exclaimed admiringly.

"I would, indeed."

"Come on then. We're off." He was impatient to be gone.

Detis busied himself with a small apparatus that folded into a compact case, explaining that it was one that might prove useful. Ora left the room but quickly returned. She too carried a small case, and she had donned a snug fitting leather garment that covered her from neck to knees.

"What's this?" demanded Carr. "Surely Miss Ora does not intend to come with us?"

"She never leaves my side," said Detis proudly.

"Nothing doing!" Carr stated emphatically. "There'll be plenty of danger on this trip. Well have no woman along – least of all your charming daughter."

_______________________

Mado was leaving everything to his friend, but he grinned in anticipation when he saw the look of anger on the girl's face.

She stamped her little foot and faced Carr valiantly. "See here, Mr. Carr Parker!" she stormed. "I'm no weakling. I'm the daughter of my father and where he goes I go. You'll take me or I'll never speak to you again."

Carr flushed. He was accustomed to his own way in most things and entirely unused to the ways of the gentler sex. He could have shaken the little vixen! But now she was standing before him and there was something in those great blue eyes besides anger; something that set his heart pounding madly.

"All right!" he agreed desperately, "have your own way."

He turned on his heel and strode to the door. Giving in to this slip of a girl! What a fool he was! But it would be great at that to have her along in the Nomad.

They found the public square deserted, the gilded dwellings hung with somber colors in mourning for Carli. Ora and Detis were very quiet and preoccupied when they entered the Nomad. The five isini of lamentation for the young prince had not yet passed.

The two Europans were delighted with the appointments and mechanisms of the little vessel from Mars. They investigated every nook and cranny of its interior during the journey and were voluble in their praise of its inventor and builder. Neither had ever set foot in a space-flier and each was seized with a longing to explore space with these two strangers from the inner planets. They would make a couple of good vagabonds along with Mado and himself, Carr thought as they expressed their feelings. But there was more serious business at hand. They were nearing Ganymede.

"Where'll we land, Detis?" Mado called from the control cabin.

"Vlor-urdin. That is their chief city. I'll guide you to the location."

_______________________

They took up their places at the ports and scanned the surface of the satellite as Mado dropped the ship into its atmosphere. A far different scene was presented than on Europa. The land was seamed and scarred, the colors of the foliage somber. Grays and browns predominated and the jungles seemed impenetrable. A river swung into view and its waters were black as the deepest night, its flow sluggish. A rank mist hung over the surface.

"The river of Charis!" exclaimed Detis. "Follow it, Mado. No, the other direction. There! It leads directly to Vlor-urdin."

By good chance they had entered the atmosphere at a point not far from their destination. In less than an hour by the Nomad's chronometer the towers of Vlor-urdin were sighted.

It was a larger city than Pala-dar and of vastly different appearance. A hollow square of squat buildings enclosed the vast workshops and storage space of the fleet of war vessels. Their huge spherical bulks rose from their cradles in tier after tier that stretched as far as the eye could reach when the Nomad had dropped to a level but slightly above the tips of the highest spires. The spires were everywhere, decorative towers at the corners of the squat buildings. Everything was black, the vessels of the fleet, the squat buildings and the spires of Vlor-urdin. Death was in the air. Rank vapor drifted in through the opened ports. There was silence in the city below them and silence in the Nomad.

Ora shuddered and drew closer to him. Carr was aware of her nearness and a lump rose in his throat. A horrible fear assailed him. Fear for the safety of the dainty Europan at his side. He found her hand; covered it protectingly with his own.
