"The people of the other three cities settled down contentedly enough in Kom, and each people built their own type of dwelling, cube or sphere or cylinder. And all mixed, intermarried, and mingled in race, with the exception of the Kanlars, the people of the cylinders. These still held apart, though unobtrusively. "And as the years went by, the scientists of Kom came to more and more wisdom. They found ways to strengthen their own bodies, so that they lived for great stretches of time, as we do yet. They sent their explorers out to other planets, they cast their vision out to the farthest stars. They learned to create life, and they learned to conquer death, almost. The flight of the soul from the body they could not control, for there is a wisdom above man's, but the body itself they could retain as moving and lifelike as in life itself, though soulless. "It seemed, indeed, that no other steps of wisdom remained up which to climb. And then, without the knowledge of the other people, the Kanlar scientists set themselves to conquer the secret of time. Unable to find a way of controlling time themselves, of moving in it at will, they created a monstrous, undreamed-of thing, a thing of shapeless, inchoate body, which was yet living, and which could transform itself, at will, into mists and vapors, and in that gaseous form could travel at will through time. And this thing the Kanlars made, setting in it three orbs of light that were its organs of sense and its seat of intelligence, and this thing is the same that you now call the Raider. "This, indeed, happened in my own lifetime, a scant score of years ago. And when the Kanlars brought their creation before the supreme council of Kom, I was a member of that council. "They explained the power of their creation, they showed its life, its intelligence. And they proposed to the council a plan which possession of the Raider made possible. "They pointed out that since the Raider could travel at will through time, it could whirl back into the past, or into the future, and seize people from every age, bringing them back to our own time to be our slaves. Always there had been none but free people in our cities, nor were slaves needed, since nearly all of our work was done by machinery, yet such was the evil plan of the Kanlars. "The council rejected the plan in horror. And it also warned the Kanlars that unless they destroyed the thing they had made, the council would hunt it out and destroy it itself. The Kanlars left in rage, and took with them the Raider, but later they promised to destroy it within a certain period of time, saying that they desired to study it further before doing so.
