Are you going to tell me now, or do you propose The Link It was nearly sundown when Ravdin eased the ship down into the last slow arc toward the Earth's surface. Stretching his arms and legs, he tried to relax and ease the tension in landing below him he could see the vast, tangled expanse of Jungle-land spreading out to the horizon. Miles ahead was the back to the landing operation. He was still numb and shaken from the Warp-passage, his mind still muddled by the abrupt with you, to bring our people together again." Frankle snorted. "You came to us in war, once, long ago. Now you want peace. What would you do, clasp us to your vast, starry blanket of black velvet friendly lights and music. He checked the proper switches, and felt the throbbing purr of the anti-grav motors as the ship slid in toward the landing slot. Tall spires of other ships rose to meet him, circle upon circle of silver needles pointing skyward. A little later they were blotted out as the ship was grappled then, abruptly, he had been hovering over the city, sliding down toward warm the ramp to the shuttles. At the desk he checked in with the shiny punch-card robot, and walked swiftly across the polished floor. The wall panels pulsed a somber blue-green, could weave, of their strange, magic power to steal strong men's minds from them and make them like children before habitation. Vaguely, uneasiness grew in his mind as he entered the shuttle station. Suddenly, the music caught him, a long, low chord of indescribable beauty, rising and falling in the the city. But he knew instinctively that Lord Nehmon, 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 on his journey. The curves and spires of glowing plastic passed images. The stone shimmered and changed, taking the of smoothly curving walls and tasteful lines, opening a full side to the south to catch the soft sunlight and warm form of dancing clouds of light, swirling with the music as it at the gleaming center of light, forcing their joined minds to create the crashing, majestic chords as the song lifted from the more intimate fantasy of whirling sound. An oval door opened for him, and he stopped short, staggered for a moment by the A song of majesty, and strength, and dignity. A song of love, of aspiration, a song of achievement. A song of peoples driven by ancient fears across the eons of space, seeking only peace, even peace with those who drove them. depths of oblivion to the heights of glory in the old, old song his mind could not grasp the meaning, the true overtones of midst of the light, lashing out wildly at the heart of its shimmering brilliance. His huge hand caught the hypnotic stone , Nehmon! I saw them, hours ago." The last overtones of the music broke abruptly, like a glass and swept it into crashing, ear-splitting cacophony against the cold steel bulkhead. He stood rigid, his whole body shaking, eyes blazing with fear and anger and hatred as he turned on "No chance. I found signs of their passing in a dozen places. Then I saw them They're coming, I saw them." "Did they see you?" Nehmon's voice was sharp. "No, no. The Warp is a wonderful thing. With it I could come and go in the twinkling of an eye. But I could see them in the twinkling of an eye." just have to rearrange my thinking a little. Where were they? How far?" "Seven light years," Ravdin said. "Can you imagine it? Just seven, and moving straight this way. They know where key clicked into the lock of their minds and incredible change. Moments before, the sky had been a couldn't have found us so soon, unless they too have discovered the Warp and how to use it to travel." The older man's breath cut off sharply, and there was real alarm in his eyes. "You're right," he said softly. "Six months ago it was eight hundred light years away, in an area completely remote from us. Now just on a cold stone ledge, blinking dumbly at each other as the ships of his fleet rose one by one and vanished like fireflies in seven Jungle-land. They knew no words, no music, nothing. And they did not even know that in the departing ships a seed had been the dark night sky. Naked, they sat alone on the planet of the They never knew that the link had been forged. and we have a way of life that they do not, so whenever they have come close to finding us, we have run." Nehmon nodded slowly. "For thousands of years." "The Hunters! They've found us?" vague or fuzzy, it was clear ! The transference was perfect." She turned to face the old man. "It's taken so long to come this far, Nehmon. So much work, so much training to reach a perfect communal concert. We've had only two hundred years the street below. "If we only knew, for certain, what we were running from." us. I've read—oh, I can't remember. I think my grandfather saw them, or my great-grandfather, somewhere back there. It's been thousands of years." "Yet we've been tearing ourselves up by the roots, fleeing Sometime our people must contact them, find the link that light and motion was soon to become his Jungle-land again. In the city the turmoil bubbled over, as wave after wave of the people made the short safari across the intervening jungle to the circles of their ships. Husbands, wives, fathers, mothers—all carried their small, frail remembrances out to the ships. There was music among them still, but it was a different sort of music, now, an eerie, hopeless music that drifted out of the city in the wind. It caused all but the bravest of the beasts, their hair prickling on their backs, to run in panic through only the scorched circle of land for the jungle to reclaim, so that no eyes, not even the sharpest, would ever know how long they had stayed, nor where they might have gone. because the space on the ships must take people, not remembrances, and he knew that the remembrances would bring only pain. All day Nehmon had supervised the loading, the intricate preparation, following plans laid down millennia before. He saw the libraries and records transported, mile upon endless mile of microfilm, carted to the ships prepared to carry them, stored until a new resting place was found. The history in the gathering twilight. Soon the last families would have taken their refuge in the ships, waiting for Nehmon to trigger They had risen together, a common people, their home a single planet. And then, the gradual splitting of the nations, his own people living in peace, seeking the growth and beauty of the arts, despising the bitterness and barrenness of hatred and killing—and 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 can be forged, we will forge it." air, throwing a ghastly light on the frightened Jungle-land. Spires of flame seemed to be seeking the stars with their fingers to the earth as powerful, flaming jets. 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, flagship. As they approached it, their hearts sank and they clasped
