The button went down on the control again. The air was suddenly thin and bitingly cold as they looked down on a world torn with war, where a hundred ships shaped like half-disks and unlike anything Duke had seen were mixed up in some maneuver. The button was pushed again, and this time there was a world below that had a port busy with similar ships, not fighting now. A third press brought them onto the surface of a heavy world that seemed to be composed of solid buildings and factories, where the ships were being outfitted with incomprehensible goods. A thing like a pipe-stem man looked up from a series of operations, made a waving motion to them, and abruptly disappeared. "Did you really think we could be the only adult race in the universe?" Flannery asked. "You're looking at the Allr, the closest cultural gestalt to us, and somewhere near our level. Now--" Something squamous perched on a rock on what seemed to be a barren world. Before it floated bright points of light that were obviously replicas of planets, with tiny lines of light between them, and a shuttling of glints along the lines. The thing seemed to look at them, briefly. A tentacle whipped up and touched Flannery, who sat with his hands off the control box. Without its use, they were abruptly back in their office. Flannery shivered, and there was strain on his face, while Duke felt his mind freeze slowly, as if with physical cold. The director cleared his throat. "Or maybe we should look at more routine things, though you might consider that we have to get ready for the day when our advancing culture touches on other cultures. Because we can't put it off forever." This time, they were in a building, like a crude shed, and there were men there, standing in front of a creature that seemed like a human in armor--but chitinous armor that was part of him. The alien suddenly turned, though Duke could now see that they were in a section behind one-way glass. Nevertheless, it seemed to sense them. Abruptly, something began pulling at his mind, as if his thoughts were being drained. Flannery hit the button again. "Telepathic race, and very immature," he said, and there was worry in his voice. "Thank God, the only one we've found, and out of our immediate line of advance." There were other scenes. A human being who walked endlessly three feet off the floor, fighting against some barrier that wasn't there, with his face frozen in fear, while creatures that seemed to be metallic moved about. "He found something while working on one of our paradynamic problems," Flannery said. "He transported himself there and has been exactly like that ever since--three years, now. So far, our desk-jockeys here haven't been able to discover exactly what line he was working on, but they're trying!" They were back in the office, and the director laid the control box on the big panel and cut off the power. He swung back to face Duke, his face tired.
