"Of course not. But the time isn't ripe yet. We'll have to wait till we know what it's all about."
They were outside then, on the palace roof, and Pegrani motioned them to a railed-in runway that circled its edge. High overhead was the shadowy blackness of the copper shell that enclosed the satellite. Huge latticed columns, line upon line of them, stretched off into the distance as far as the eye could follow; enormous white metal supports that carried the immense weight of the covering which retained the dense and humid atmosphere. Myriads of tiny blue-white suns there seemed to be, stretching off between the columns, carried on thick cables and radiating the artificial daylight of the interior. Hot, damp odors wafted across the roof, the odors of decayed vegetation.
Most amazing of all, were the dwellings. In orderly rows like the columns, they were flat topped cylindrical things that reminded Blaine of nothing so much as the tanks of an oil refinery back home. And the space between was overgrown with dense tropical vegetation, tangled and matted and shooting transparent tubular stems up to a height of a hundred feet or more where they sprouted great spherical growths that looked like enormous sponges. Of a sickly, pale green hue, these growths overran everything; climbed the columns and were lost in the shadows above the multitude of lights. The big sponge-like blossoms expanded and contracted rhythmically. Breathing, they were, like living things. Specially cultivated plant life to assist in maintaining the oxygen supply balance by decomposition of carbon dioxide. A marvelous artificial world!
"The streets and moving ways are in tunnels beneath the soil," Pegrani was explaining. "What lies before you is the city of Ilen-dar, capital city of the empire, and like all other cities of Antrid, it is self-sustaining. The vegetation is inedible, all of our food is synthetic and highly concentrated. You were fed by intravenous injection while under the influence of the language machines. Our heat and power is obtained from the internal fires of Antrid, and, alas, these are being exhausted with great rapidity. Our shortage of power is becoming acute, and again our peoples are facing extinction."
That explained their need for the k-metal. It came to Blaine in a flash that Antrid was in sore straits and that this expedition to Earth had more back of it than had been revealed. Even with the supply of k-metal Antazzo had stolen, they could not carry on forever.
A screaming object went hurtling through the blackness over their heads. Something, a vehicle of enormous size with rows of lighted ports on the under side, that roared its way under the roof of copper and was gone in an instant.
"One of our monorail cars," Pegrani told them: "a complete system interconnects all cities and divisions. They are capable of circling the globe in a day of your time."
Their familiarity with conditions on Earth was astonishing. Probably Antazzo was but one of many spies who had been sent to the inner planets. Pegrani discussed the speed in their own terms.
