The Cold Equations

by Tom Godwin

  But when the broth was prepared, and cooled enough, the pups could not eat it. He tried making it weaker, tried it mixed with corn and herb soup, tried corn and herb soups alone. They could eat nothing he prepared for them.

  When gray daylight entered the room he had tried everything possible and had failed. He sat wearily in his chair and watched them, defeated. They were no longer crying in their hunger and when he touched them they did not move as they had done before.

  They would be dead before the day was over and the only chance men had ever had to have prowlers as their friends and allies would be gone.

  The first rays of sunrise were coming into the room, revealing fully the frail thinness of the pups, when there was a step outside and Julia's voice:

  "Father?"

  "Come in, Julia," he said, not moving.

  She entered, still a pale shadow of the reckless girl who had fought a unicorn, even though she was slowly regaining her normal health. She carried young Johnny in one arm, in her other hand his little bottle of milk. Johnny was hungry—there was never quite enough milk for him—but he was not crying. Ragnarok children did not cry . . .

  She saw the pups and her eyes went wide.

  "Prowlers—baby prowlers! Where did you get them?"

  He told her and she went to them, to look down at them and say, "If you and their father hadn't helped each other that day they wouldn't be here, nor you, nor I, nor Johnny—none of us in this room."

  "They won't live out the day," he said. "They have to have milk—and there isn't any."

  She reached down to touch them and they seemed to sense that she was something different. They stirred, making tiny whimpering sounds and trying to move their heads to nuzzle at her fingers.

  Compassion came to her face, like a soft light.

  "They're so young," she said. "So terribly young to have to die . . ."

  She looked at Johnny and at the little bottle that held his too-small morning ration of milk.

  "Johnny—Johnny—" Her words were almost a whisper. "You're hungry—but we can't let them die. And someday, for this, they will fight for your life."

  She sat on the bed and placed the pups in her lap beside Johnny. She lifted a little black head with gentle fingers and a little pink mouth ceased whimpering as it found the nipple of Johnny's bottle.

  Johnny's gray eyes darkened with the storm of approaching protest. Then the other pup touched his hand, crying in its hunger, and the protest faded as surprise and something like sudden understanding came into his eyes.

  Julia withdrew the bottle from the first pup and transferred it to the second one. Its crying ceased and Johnny leaned forward to touch it again, and the one beside it.

  He made his decision with an approving sound and leaned back against his mother's shoulder, patiently awaiting his own turn and their presence accepted as though they had been born his brother and sister.

  * * *

  The golden light of the new day shone on them, on his daughter and grandson and the prowler pups, and in it he saw the bright omen for the future.

  His own role was nearing its end but he had seen the people of Ragnarok conquer their environment in so far as Big Winter would ever let it be conquered. The last generation was being born, the generation that would meet the Gerns, and now they would have their final ally. Perhaps it would be Johnny who led them on that day, as the omen seemed to prophesy.

  He was the son of a line of leaders, born to a mother who had fought and killed a unicorn. He had gone hungry to share what little he had with the young of Ragnarok's most proud and savage species and Fenrir and Sigyn would fight beside him on the day he led the forces of the hell-world in the battle with the Gerns who thought they were gods.

  Could the Gerns hope to have a leader to match?

  Part 5

  John Humbolt, leader, stood on the wide stockade wall and watched the lowering sun touch the western horizon—far south of where it had set when he was a child. Big Summer was over and now, in the year two hundred, they were already three years into Big Fall. The Craigs had been impassable with snow for five years and the country at the north end of the plateau, where the iron had been found, had been buried under never-melting snow and growing glaciers for twenty years.

  There came the soft tinkling of ceramic bells as the herd of milk goats came down off the hills. Two children were following and six prowlers walked with them, to protect them from wild unicorns.

  There were not many of the goats. Each year the winters were longer, requiring the stocking of a larger supply of hay. The time would come when the summers would be so short and the winters so long that they could not keep goats at all. And by then, when Big Winter had closed in on them, the summer seasons would be too short for the growing of the orange corn. They would have nothing left but the hunting.

  They had, he knew, reached and passed the zenith of the development of their environment. From a low of forty-nine men, women and children in dark caves they had risen to a town of six thousand. For a few years they had had a way of life that was almost a civilization but the inevitable decline was already under way. The years of frozen sterility of Big Winter were coming and no amount of determination or ingenuity could alter them. Six thousand would have to live by hunting—and one hundred, in the first Big Winter, had found barely enough game.

  They would have to migrate in one of two different ways: they could go to the south as nomad hunters—or they could go to other, fairer worlds in ships they took from the Gerns.

  The choice was very easy to make and they were almost ready.

  In the workshop at the farther edge of town the hyperspace transmitter was nearing completion. The little smelter was waiting to receive the lathe and other iron and steel and turn them into the castings for the generator. Their weapons were ready, the mockers were trained, the prowlers were waiting. And in the massive corral beyond town forty half-tame unicorns trampled the ground and hated the world, wanting to kill something. They had learned to be afraid of Ragnarok men but they would not be afraid to kill Gerns . . .

  The children with the goats reached the stockade and two of the prowlers, Fenrir and Sigyn, turned to see him standing on the wall. He made a little motion with his hand and they came running, to leap up beside him on the ten-foot-high wall.

  "So you've been checking up on how well the young ones guard the children?" he asked.

  Sigyn lolled out her tongue and her white teeth grinned at him in answer. Fenrir, always the grimmer of the two, made a sound in his throat in reply.

  Prowlers developed something like a telepathic rapport with their masters and could sense their thoughts and understand relatively complex instructions. Their intelligence was greater, and of a far more mature order, than that of the little mockers but their vocal cords were not capable of making the sounds necessary for speech.

  He rested his hands on their shoulders, where their ebony fur was frosted with gray. Age had not yet affected their quick, flowing movement but they were getting old—they were only a few weeks short of his own age. He could not remember when they had not been with him . . .

  Sometimes it seemed to him he could remember those hungry days when he and Fenrir and Sigyn shared together in his mother's lap—but it was probably only his imagination from having heard the story told so often. But he could remember for certain when he was learning to walk and Fenrir and Sigyn, full grown then, walked tall and black beside him. He could remember playing with Sigyn's pups and he could remember Sigyn watching over them all, sometimes giving her pups a bath and his face a washing with equal disregard for their and his protests. Above all he could remember the times when he was almost grown; the wild, free days when he and Fenrir and Sigyn had roamed the mountains together. With a bow and a knife and two prowlers beside him he had felt that there was nothing on Ragnarok that they could not conquer; that there was nothing in the universe they could not defy together . . .

  * * *

  There was a flicker of
black movement and a young messenger prowler came running from the direction of the council hall, a speckle-faced mocker clinging to its back. It leaped up on the wall beside him and the mocker, one that had been trained to remember and repeat messages verbatim, took a breath so deep that its cheeks bulged out. It spoke, in a quick rush like a child that is afraid it might forget some of the words:

  "You will please come to the council hall to lead the discussion regarding the last preparations for the meeting with the Gerns. The transmitter is complete."

  * * *

  The lathe was torn down the next day and the smelter began to roar with its forced draft. Excitement and anticipation ran through the town like a fever. It would take perhaps twenty days to build the generator, working day and night so that not an hour of time would be lost, forty days for the signal to reach Athena, and forty days for the Gern cruiser to reach Ragnarok—

  In one hundred days the Gerns would be there!

  The men who would engage in the fight for the cruiser quit trimming their beards. Later, when it was time for the Gerns to appear, they would discard their woolen garments for ones of goat skin. The Gerns would regard them as primitive inferiors at best and it might be of advantage to heighten the impression. It would make the awakening of the Gerns a little more shocking.

  An underground passage, leading from the town to the concealment of the woods in the distance, had long ago been dug. Through it the women and children would go when the Gerns arrived.

  There was a level area of ground, just beyond the south wall of town, where the cruiser would be almost certain to land. The town had been built with that thought in mind. Woods were not far from both sides of the landing site and unicorn corrals were hidden in them. From the corrals would come the rear flanking attack against the Gerns.

  The prowlers, of course, would be scattered among all the forces.

  * * *

  The generator was completed and installed on the nineteenth night. Charley Craig, a giant of a man whose red beard gave him a genially murderous appearance, opened the valve of the water pipe. The new wooden turbine stirred and belts and pulleys began to spin. The generator hummed, the needles of the dials climbed, flickered, and steadied.

  Norman Lake looked from them to Humbolt, his pale gray eyes coldly satisfied. "Full output," he said. "We have the power we need this time."

  Jim Chiara was at the transmitter and they waited while he threw switches and studied dials. Every component of the transmitter had been tested but they had not had the power to test the complete assembly.

  "That's it," he said at last, looking up at them. "She's ready, after almost two hundred years of wanting her."

  Humbolt wondered what the signal should be and saw no reason why it should not be the same one that had been sent out with such hope a hundred and sixty-five years ago.

  "All right, Jim," he said. "Let the Gerns know we're waiting for them—make it 'Ragnarok calling' again."

  The transmitter key rattled and the all-wave signal that the Gerns could not fail to receive went out at a velocity of five light-years a day:

  Ragnarok calling—Ragnarok calling—Ragnarok calling—

  It was the longest summer Humbolt had ever experienced. He was not alone in his impatience—among all of them the restlessness flamed higher as the slow days dragged by, making it almost impossible to go about their routine duties. The gentle mockers sensed the anticipation of their masters for the coming battle and they became nervous and apprehensive. The prowlers sensed it and they paced about the town in the dark of night; watching, listening, on ceaseless guard against the mysterious enemy their masters waited for. Even the unicorns seemed to sense what was coming and they rumbled and squealed in their corrals at night, red-eyed with the lust for blood and sometimes attacking the log walls with blows that shook the ground.

  The interminable days went their slow succession and summer gave way to fall. The hundredth day dawned, cold and gray with the approach of winter; the day of the Gerns.

  But no cruiser came that day, nor the next.

  He stood again on the stockade wall in the evening of the third day, Fenrir and Sigyn beside him. He listened for the first dim, distant sound of the Gern cruiser and heard only the moaning of the wind around him.

  Winter was coming. Always, on Ragnarok, winter was coming or the brown death of summer. Ragnarok was a harsh and barren prison, and no amount of desire could ever make it otherwise. Only the coming of a Gern cruiser could ever offer them the bloody, violent opportunity to regain their freedom.

  But what if the cruiser never came?

  It was a thought too dark and hopeless to be held. They were not asking a large favor of fate, after two hundred years of striving for it; only the chance to challenge the Gern Empire with bows and knives . . .

  Fenrir stiffened, the fur lifting on his shoulders and a muted growl coming from him. Then Humbolt heard the first whisper of sound; a faint, faraway roaring that was not the wind.

  He watched and listened and the sound came swiftly nearer, rising in pitch and swelling in volume. Then it broke through the clouds, tall and black and beautifully deadly. It rode down on its rockets of flame, filling the valley with its thunder, and his heart hammered with exultation.

  It had come—the cruiser had come!

  He turned and dropped the ten feet to the ground inside the stockade. The warning signal was being sounded from the center of town; a unicorn horn that gave out the call they had used in the practice alarms. Already the women and children would be hurrying along the tunnels that led to the temporary safety of the woods beyond town. The Gerns might use their turret blasters to destroy the town and all in it before the night was over. There was no way of knowing what might happen before it ended. But whatever it was, it would be the action they had all been wanting.

  He ran to where the others would be gathering, Fenrir and Sigyn loping beside him and the horn ringing wild and savage and triumphant as it announced the end of two centuries of waiting.

  * * *

  The cruiser settled to earth in the area where it had been expected to land, towering high above the town with its turret blasters looking down upon the houses.

  Charley Craig and Norman Lake were waiting for him on the high steps of his own house in the center of town where the elevation gave them a good view of the ship yet where the fringes of the canopy would conceal them from the ship's scanners. They were heavily armed, their prowlers beside them and their mockers on their shoulders.

  Elsewhere, under the connected rows of concealing canopies, armed men were hurrying to their prearranged stations. Most of them were accompanied by prowlers, bristling and snarling as they looked at the alien ship. A few men were deliberately making themselves visible not far away, going about unimportant tasks with only occasional and carefully disinterested glances toward the ship. They were the bait, to lure the first detachment into the center of town . . .

  "Well?" Normal Lake asked, his pale eyes restless with his hunger for violence. "There's our ship—when do we take her?"

  "Just as soon as we get them outside it," he said. "We'll use the plan we first had—wait until they send a full force to rescue the first detachment and then hit them with everything we have."

  His black, white-nosed mocker was standing in the open doorway and watching the hurrying men and prowlers with worried interest: Tip, the great-great-great-great grandson of the mocker that had died with Howard Lake north of the plateau. He reached down to pick him up and set him on his shoulder, and said:

  "Jim?"

  "The longbows are ready," Tip's treble imitation of Jim Chiara's voice answered. "We'll black out their searchlights when the time comes."

  "Andy?" he asked.

  "The last of us for this section are coming in now," Andy Taylor answered.

  He made his check of all the subleaders, then looked up to the roof to ask, "All set, Jimmy?"

  Jimmy Stevens' grinning face appeared over the edge. "Ten crossbows
are cocked and waiting up here. Bring us our targets."

  They waited, while the evening deepened into near-dusk. Then the airlock of the cruiser slid open and thirteen Gerns emerged, the one leading them wearing the resplendent uniform of a subcommander.

  "There they come," he said to Lake and Craig. "It looks like we'll be able to trap them in here and force the commander to send out a full-sized force. We'll all attack at the sound of the horn and if you can hit their rear flanks hard enough with the unicorns to give us a chance to split them from this end some of us should make it to the ship before they realize up in the control room that they should close the airlocks.

  "Now"—he looked at the Gerns who were coming straight toward the stockade wall, ignoring the gate to their right—"you'd better be on your way. We'll meet again before long in the ship."

  Fenrir and Sigyn looked from the advancing Gerns to him with question in their eyes after Lake and Craig were gone, Fenrir growling restlessly.
