"There," he said, "beyond the top of the arrowhead, is where we were going when the Gerns stopped us a hundred and twenty years ago and left us to die on Ragnarok. It’s so far that Athena’s sun can’t be seen from here, so far that it will be another hundred and fifteen years before our first signal gets there. Why is it, then, that you and all the other groups of children have to learn such things as history, physics, the Gern language, and the way to fire a Gern blaster?"
The hand of every child went up. West selected eight-year-old Clifton Humbolt. "Tell us, Clifton," he said.
"Because," Clifton answered, "a Gern cruiser might pass by a few light-years out at any time and pick up our signals. So we have to know all we can about them and how to fight them because there aren’t very many of us yet."
"The Gerns will come to kill us," little Marie Chiara said, her dark eyes large and earnest. "They’ll come to kill us and to make slaves out of the ones they don’t kill, like they did with the others a long time ago. They’re awful mean and awful smart and we have to be smarter than they are."
Howard looked again at the Athena constellation, thinking, I hope they come just as soon as I’m old enough to fight them, or even tonight….
"Teacher," he asked, "how would a Gern cruiser look if it came tonight? Would it come from the Athena arrowhead?"
"It probably would," West answered. "You would see its rocket blast, like a bright trail of fire——"
A bright trail of fire burst suddenly into being, coming from the constellation of Athena and lighting up the woods and hills and their startled faces as it arced down toward them.
"It’s them!" a treble voice exclaimed and there was a quick flurry of movement as Howard and the other older children shoved the younger children behind them.
Then the light vanished, leaving a dimming glow where it had been.
"Only a meteor," West said. He looked at the line of older children who were standing protectingly in front of the younger ones, rocks in their hands with which to ward off the Gerns, and he smiled in the way he had when he was pleased with them.
Howard watched the meteor trail fade swiftly into invisibility and felt his heartbeats slow from the first wild thrill to gray disappointment. Only a meteor….
But someday he might be leader and by then, surely, the Gerns would come. If not, he would find some way to make them come.
Ten years later Howard Lake was leader. There were three hundred and fifty of them then and Big Spring was on its way to becoming Big Summer. The snow was gone from the southern end of the plateau and once again game migrated up the valleys east of the caves.
There were many things to be done now that Big Winter was past and they could have the chance to do them. They needed a larger pottery kiln, a larger workshop with a wooden lathe, more diamonds to make cutting wheels, more quartz crystals to make binoculars and microscopes. They could again explore the field of inorganic chemistry, even though results in the past had produced nothing of value, and they could, within a few years, resume the metal prospecting up the plateau—the most important project of all.
Their weapons seemed to be as perfect as was possible but when the Gerns came they would need some quick and certain means of communication between the various units that would fight the Gerns. A leader who could not communicate with his forces and coordinate their actions would be helpless. And they had on Ragnarok a form of communication, if trained, that the Gerns could not detect or interfere with electronically: the mockers.
The Craigs were still white and impassable with snow that summer but the snow was receding higher each year. Five years later, in the summer of one hundred and thirty-five, the Craigs were passable for a few weeks.
Lake led a party of eight over them and down into the chasm. They took with them two small cages, constructed of wood and glass and made airtight with the strong medusabush glue. Each cage was equipped with a simple air pump and a pressure gauge.
They brought back two pairs of mockers as interested and trusting captives, together with a supply of the orange corn and a large amount of diamonds. The mockers, in their pressure-maintained cages, were not even aware of the increase in elevation as they were carried over the high summit of the Craigs.
To Lake and the men with him the climb back up the long, steep slope of the mountain was a stiff climb to make in one day but no more than that. It was hard to believe that it had taken Humbolt and Barber almost three days to climb it and that Barber had died in the attempt. It reminded him of the old crossbows that Humbolt and the others had used. They were thin, with a light pull, such as the present generation boys used. It must have required courage for the old ones to dare unicorn attacks with bows so thin that only the small area behind the unicorn’s jaws was vulnerable to their arrows….
When the caves were reached, a very gradual reduction of pressure in the mocker cages was started; one that would cover a period of weeks. One pair of mockers survived and had two young ones that fall. The young mockers, like the first generation of Ragnarok-born children of many years before, were more adapted to their environment than their parents were.
The orange corn was planted, using an adaptation method somewhat similar to that used with the mockers. It might have worked had the orange corn not required such a long period of time in which to reach maturity. When winter came only a few grains had formed.
They were saved for next year’s seeds, to continue the slow adaptation process.
By the fifth year the youngest generation of mockers was well adapted to the elevation of the caves but for a susceptibility to a quickly fatal form of pneumonia which made it necessary to keep them from exposing themselves to the cold or to any sudden changes of temperature.
Their intelligence was surprising and they seemed to be partially receptive to human thoughts, as Bill Humbolt had written. By the end of the fifteenth year their training had reached such a stage of perfection that a mocker would transmit or not transmit with only the unspoken thought of its master to tell it which it should be. In addition, they would transmit the message to whichever mocker their master’s thought directed. Presumably all mockers received the message but only the mocker to whom it was addressed would repeat it aloud.
They had their method of communication. They had their automatic crossbows for quick, close fighting, and their long range longbows. They were fully adapted to the 1.5 gravity and their reflexes were almost like those of prowlers—Ragnarok had long ago separated the quick from the dead.
There were eight hundred and nineteen of them that year, in the early spring of one hundred and fifty, and they were ready and impatient for the coming of the Gerns.
Then the transmitter, which had been in operation again for many years, failed one day.
George Craig had finished checking it when Lake arrived. He looked up from his instruments, remarkably similar in appearance to a sketch of the old George Ord—a resemblance that had been passed down to him by his mother—and said:
"The entire circuit is either gone or ready to go. It’s already operated for a lot longer than it should have."
"It doesn’t matter," Lake said. "It’s served its purpose. We won’t rebuild it.
"
George watched him questioningly.
"It’s served its purpose," he said again. "It didn’t let us forget that the Gerns will come again. But that isn’t enough, now. The first signal won’t reach Athena until the year two thirty-five. It will be the dead of Big Winter again then. They’ll have to fight the Gerns with bows and arrows that the cold will make as brittle as glass. They won’t have a chance."
