Within ten minutes the divisions had been made, and the Radiant People had entered the aircars and, outside the laboratory, risen free of the Earth, and turned, each in its proper direction, for the Gens of its assignment. The Sarkas and Jaska watched them go. There remained but one aircar, standing outside on half a dozen of those grim tentacles, with two tentacles swinging free, undulating to and fro like serpents. Harnessed electricity actuating the tentacles--cars and tentacles subservient to the cubes. The aircars safely on their way, Sarka stepped to the Master Beryl, tuned it down to normal speed, and signalled the Spokesmen of the Gens. "The Moon and Mars are in alliance against us, and Dalis has allied himself and his Gens with the ruler of the Moon! I don't know yet what form the attack will take, but know this: that the safety of the world, of all its people, rests in your hands, and that the war into which we are going is potentially more vast than expected when this venture began, and more devastating than the fight with the aircars of the Moon! Coming to you, in aircars which we managed to take from the Moon-people, are such of the people of the Gens of Dalis as were able to return with me. Question them, gather all the information you can about them, and through them keep control of the cubes which pilot the aircars, for in the cubes, I believe, lies the secret of our possible victory in the fight to come!" * * * * * Sarka scarcely knew why he had spoken the last sentence. It was as though something deep within him had risen up, commanded him to speak, and deeper yet, far back in his consciousness, was a mental picture of the devastation he had witnessed on his flight above the area that had once housed the Gens of Dalis. For in that ghastly area, he believed, was embodied an idea greater than mere wanton destruction, just as there was an idea back of the fiery lights from Mars greater than mere display. Somehow the two were allied, and Sarka believed that, between the blue column, and the fiery lights from Mars, the fate of the world rested. He could, he believed, by manipulation of the Beryls that yet remained, maneuver the world away from that blue column--which on the Earth was invisible. But to have done so would have thwarted the very purpose for which this mad voyage had been begun. The world had been started on its mad journey into space for the purpose of attacking and colonizing the Moon and Mars. The Moon had been colonized by the Gens of Dalis, already in potential revolt against the Earth. Mars was next, and by forcing the Earth into close proximity to Mars the people of the Moon had played into the hands of Earth-people--if the people of Earth were capable of carrying out the program of expansion originally proposed by Sarka!
