<passage>:
Are you going to tell me now, or do you propose to waste a few hours of my time first?" "There is no mystery," Ravdin said softly. "We stayed behind to plead for peace." his face tired. "I might have known. Peace! Where have your people gone?" Ravdin met him eye for eye. "I can't say." The Hunter laughed. "Let's be precise, you don't Jungle-land spreading out to the horizon. Miles ahead was the bright circle of the landing field and the sparkling glow of the city beyond. Ravdin peered to the north of the city, hoping to Dana's voice was sharp. "We're telling you the truth. We want peace, nothing more. This constant hunting and running is senseless, exhausting to both of us. We want to make peace A bell chimed softly in his ear. Ravdin forced his attention back to the landing operation. He was still numb and shaken catch a glimpse of the concert before his ship was swallowed excited, too eager to be home, for his mind was still reeling from the fearful discovery of his journey. The station was completely empty as Ravdin walked down anticipating his return, would not be at the concert. Riding the shuttle over the edges of Jungle-land toward the shining bright beauty of the city, Ravdin settled back, trying to clear his mind of the shock and horror he had encountered desperately to reach into the heart of it, to become part of it. Ravdin and Dana stood there, trancelike, staring transfixed at the gleaming center of light, forcing their joined minds to create the crashing, majestic chords as the song lifted from the body frozen in mid-air, and then, abruptly, she was gone, leaving only the barest flickering image of her fiery hair. The music slowed, singing softly, and Ravdin could see the old man waiting in the room. Nehmon rose, his gaunt face and Ravdin and Dana. His voice was a raging storm of bitterness drowning out the dying strains of the music. "Spies! You thought you could steal my mind away, make Nehmon sighed wearily. "No one that we know." He came," he said sadly. "We can run away." The bright street below the oval window was empty and quiet. Not a breath of air stirred in the city. Ravdin stared out in bitter silence. "Yes, we can run away. Just as we always have before. After we have worked so hard, accomplished so trailed off to silence. He stared at Nehmon, seeking in the old Nehmon and his people "I know. How well I know." "Yet now the Hunters come again, and again we must run away." Ravdin stared at the old man, his eyes suddenly bright. "Nehmon, when I saw those ships I began thinking." "I've spent many years thinking, my son." "Not what I've been thinking." Ravdin sat down, clasping his hands in excitement. "The Hunters come and we run away, Nehmon. Think about that for a moment. We run, and we run, and we run. From what? We run from the Hunters. They're hunting us "Animals fight. We do not. We fought once, like animals, and now we must run from the Hunters who continue to fight like animals. So be it. Let the Hunters fight." Ravdin shook his head. "Do you mean that the Hunters are not men like us?" he said. "That's what you're saying, that on the polished pavement as the people passed slowly, their voices carrying a hint of puzzled uneasiness. "The concert's over!" Ravdin walked to the window, feeling a chill pass through him. "So soon, I wonder why?" Eagerly he searched the faces passing in the street for Dana's face, afraid ." Ravdin turned away from his bride. "Tell her," he said to the old man. Dana looked at them, her gray eyes widening in horror. "The Hunters! They've found us?" Ravdin nodded wordlessly. Her hands trembled as she sat down, and there were tears leave now. Not when we've come so far." Ravdin nodded. "That's the trouble. They come closer every time. This time they will catch us. Or the next time, or the next. And that will be the end of everything for us, unless we running from." There was a startled silence. The girl's breath came in a gasp and her eyes widened as his words sank home. "Ravdin," anyone ever seen a Hunter?" Ravdin's hand trembled. "I—I don't know. None of us living now, no. It's been too long since they last actually found Dana's face glowed with excitement, alive with new vitality, new hope. "Ravdin, can't you see? They might have changed. Nehmon's voice broke in, almost harshly, as he faced the excited pair. "The Hunters don't have concerts," he said grimly. "You're deluding yourself, Dana. They laugh at our Nehmon met her steady eyes, read the strength and determination changed, you wouldn't stand a chance. You'd never come back, Dana." "But she's right all the same," Ravdin said softly. "You're wrong, my lord. We can't continue this way if we're to survive. Sometime our people must contact them, find the link that was once between us, and forge it strong again. We could do it, Dana and I." "I could forbid you to go." To run away. In the darkness of secrecy, to be gone, without a trace, without symbol or vestige of their presence, leaving only the scorched circle of land for the jungle to reclaim, In the rounded room of his house, Lord Nehmon dispatched would not be shaken. The day was almost gone as the last ships began to fill. Nehmon turned to Ravdin and Dana, his face lined and tired. "You'll have to go soon," he said. "The city will be burned, of course, as always. You'll be left with food, and with weapons against the jungle. The Hunters will know that we've been here, but they'll not know when, nor where we have gone." He paused. "It will be up to you to see that they don't learn." Dana shook her head. "We'll tell them nothing, unless it's safe for them to know." "They'll question you, even torture you." the Hunters, under an iron heel of militarism, of government for the perpetuation of government, split farther and farther from them. It was an ever-widening split as the Hunters sneered and ridiculed, and then grew to hate Ravdin's people for all the things the Hunters were losing: peace, love, happiness. Ravdin knew of his people's slowly dawning awareness count-down." "We will be safe, outside the city." Dana gripped her husband's hand, trying to transmit to him some part of her strength and confidence. "Wish us the best, Nehmon. If a link They were squat, misshapen vessels, circling down like vultures, hissing, screeching, landing with a grinding crash in the tall thicket near the place where the city had stood. Ravdin's signal had guided them in, and the Hunters had seen them, dull eyes, weapons strapped to their trim uniforms. The Hunters had blinked at them, unbelieving, with their weapons held at ready. Ravdin and Dana were seized and led to the flagship. As they approached it, their hearts sank and they clasped hands to bolster their failing hope. The leader of the Hunters looked up from his desk as they his eyes on them for a long moment. Finally he said, "Well?" Ravdin glanced briefly at Dana's white face. His voice seemed weak and high-pitched in comparison to the Hunter's baritone. "You are the leader of the Hunters?"
