Tom Godwin - Space Prison

A lone prowler came on the eleventh night following the wall’s completion. It came silently, in the dead of night, and it learned how to reach in and tear apart the leather lashings that held the pointed stakes in place and then jerk the stakes out of their sockets. It was seen as it was removing the third stake—which would have made a large enough opening for it to come through—and shot. It fell back and managed to escape into the woods, although staggering and bleeding.

The next night the stockade was attacked by dozens of prowlers who simultaneously began removing the pointed stakes in the same manner employed by the prowler of the night before. Their attack was turned back with heavy losses on both sides and with a dismayingly large expenditure of precious ammunition.

There could be no doubt about how the band of prowlers had learned to remove the stakes: the prowler of the night before had told them before it died. It was doubtful that the prowlers had a spoken language, but they had some means of communication. They worked together and they were highly intelligent, probably about halfway between dog and man.

The prowlers were going to be an enemy even more formidable than Prentiss had thought.

The missing stakes were replaced the next day and the others were tied down more securely. Once again the camp was prowler proof—but only for so long as armed guards patrolled inside the walls to kill attacking prowlers during the short time it would take them to remove the stakes.

The hunting parties suffered unusually heavy losses from prowler attacks that day and that evening, as the guards patrolled inside the walls, Lake said to Prentiss:

"The prowlers are so damnably persistent. It isn’t that they’re hungry—they don’t kill us to eat us. They don’t have any reason to kill us—they just hate us."

"They have a reason," Prentiss said. "They’re doing the same thing we’re doing: fighting for survival."

Lake’s pale brows lifted in question.

"The prowlers are the rulers of Ragnarok," Prentiss said. "They fought their way up here, as men did on Earth, until they’re master of every creature on their world. Even of the unicorns and swamp crawlers. But now we’ve come and they’re intelligent enough to know that we’re accustomed to being the dominant species, ourselves.

"There can’t be two dominant species on the same world—and they know it. Men or prowlers—in the end one is going to have to go down before the other."

"I suppose you’re right," Lake said. He looked at the guards, a fourth of them already reduced to bows and arrows that they had not yet had time to learn how to use. "If we win the battle for supremacy it will be a long fight, maybe over a period of centuries. And if the prowlers win—it may all be over within a year or two."

The giant blue star that was the other component of Ragnarok’s binary grew swiftly in size as it preceded the yellow sun farther each morning. When summer came the blue star would be a sun as hot as the yellow sun and Ragnarok would be between them. The yellow sun would burn the land by day and the blue sun would sear it by the night that would not be night. Then would come the brief fall, followed by the long, frozen winter when the yellow sun would shine pale and cold, far to the south, and the blue sun would be a star again, two hundred and fifty million miles away and invisible behind the cold yellow sun.

The Hell Fever lessened with the completion of the shelters but it still killed each day. Chiara and his helpers worked with unfaltering determination to find a cure for it but the cure, if there was one, eluded them. The graves in the cemetery were forty long by forty wide and more were added each day. To all the fact became grimly obvious: they were swiftly dying out and they had yet to face Ragnarok at its worst.

The old survival instincts asserted themselves and there were marriages among the younger ones. One of the first to marry was Julia.

She stopped to talk to Prentiss one evening. She still wore the red skirt, now faded and patched, but her face was tired and thoughtful and no longer bold.

"Is it true, John," she asked, "that only a few of us might be able to have children here and that most of us who tried to have children in this gravity would die for it?"

"It’s true," he said. "But you already knew that when you married."

"Yes … I knew it." There was a little silence. "All my life I’ve had fun and done as I pleased. The human race didn’t need me and we both knew it. But now—none of us can be apart from the others or be afraid of anything. If we’re selfish and afraid there will come a time when the last of us will die and there will be nothing on Ragnarok to show we were ever here.

"I don’t want it to end like that. I want there to be children, to live after we’re gone. So I’m going to try to have a child. I’m not afraid and I won’t be."

When he did not reply at once she said, almost self-consciously, "Coming from me that all sounds a little silly, I suppose."

"It sounds wise and splendid, Julia," he said, "and it’s what I thought you were going to say."

Full spring came and the vegetation burst into leaf and bud and bloom, quickly, for its growth instincts knew in their mindless way how short was the time to grow and reproduce before the brown death of summer came. The prowlers were suddenly gone one day, to follow the spring north, and for a week men could walk and work outside the stockade without the protection of armed guards.

Then the new peril appeared, the one they had not expected: the unicorns.

The stockade wall was a blue-black rectangle behind them and the blue star burned with the brilliance of a dozen moons, lighting the woods in blue shadow and azure light. Prentiss and the hunter walked a little in front of the two riflemen, winding to keep in the starlit glades.

"It was on the other side of the next grove of trees," the hunter said in a low voice. "Fred was getting ready to bring in the rest of the woods goat. He shouldn’t have been more than ten minutes behind me—and it’s been over an hour."

They rounded the grove of trees. At first it seemed there was nothing before them but the empty, grassy glade. Then they saw it lying on the ground no more than twenty feet in front of them.

It was—it had been—a man. He was broken and stamped into hideous shapelessness and something had torn off his arms.

For a moment there was dead silence, then the hunter whispered, "What did that?"

The answer came in a savage, squealing scream and the pound of cloven hooves. A formless shadow beside the trees materialized into a monstrous charging bulk; a thing like a gigantic gray bull, eight feet tall at the shoulders, with the tusked, snarling head of a boar and the starlight glinting along the curving, vicious length of its single horn.

"Unicorn!" Prentiss said, and jerked up his rifle.

The rifles cracked in a ragged volley. The unicorn squealed in fury and struck the hunter, catching him on its horn and hurling him thirty feet. One of the riflemen went down under the unicorn’s hooves, his cry ending almost as soon as it began.

The unicorn ripped the sod in deep furrows as it whirled back to Prentiss and the remaining rifleman; not turning in the manner of four-footed beasts of Earth but rearing and spinning on its hind feet. It towered above them as it whirled, the tip of its horn fifteen feet above the ground and its hooves swinging around like great clubs.

Prentiss shot again, his sights on what he hoped would be a vital area, and the rifleman shot an instant later.

The shots went true. The unicorn’s swing brought it on around but it collapsed, falling to the ground with jarring heaviness.
