Chapter 6: 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?”
