The Crystal Variation (2 page)

So they had returned from wherever it was they had gone, sowing world-eaters, robot armor, and destruction as they came. . . .

It had been a big war—the First Phase, they called it, fought well before his time—and the after-effects spread over generations. That those refusing the initial offer of
sheriekas
guidance had supposed they’d won the war rather than a battle meant . . . It meant that Jela was here, fighting a battle centuries later . . . and that there was no pretense from the enemy, now, of benevolent oversight.

Jela blinked against the glare, pulling his mind back from its ramble. There was a real danger, with your Generalist, of feeding them so much info they got lost in their own thoughts, and never came out again.

He couldn’t afford that—not here. Not yet. He had time, he had duty. All he needed to do was get off this planet, back to a base and . . .

His timer shook silently against his wrist. Water.

He leaned into the warm boulder and dug into the left leg pouch, fingers counting over the sealed bulbs. Ten. That meant that there were still ten in the right leg pouch. He always drew first from the left, ever since the fight where he’d broken his right leg.

The leg ached in sympathy with the thought, as it sometimes did, and M. Jela Granthor’s Guard, Generalist, finished his water, uncurled himself, stretched, and danced several fight moves to bring up his attention level. Feeling considerably refreshed—his was a resilient Strain—he moved around the boulder, heading down.

Behind him, his shadow was flung back across a day’s walk or more as he strode across the ridge, but there was no one there to notice.

FROM ORBIT
it had seemed clear that something . . . unusual . . . had been at work on the world, and that a good deal of time and energy had been spent in this, the last of the river valleys likely to have retained life under the onslaught of meteor-storms and radiation bursts. After concluding that his vessel would not in fact leave the surface in its current state, there’d been little left to do but sit and hope—or explore the structures on either side of the river. Being a Generalist—and an M—he’d naturally opted for exploration.

Moments after stepping around the boulder and moving on his way, he realized that, somehow, he was not exactly where he thought he should be. He was not overlooking the valley that led to the tip of the former river delta, but was instead on the rim of a side valley.

Curiosity drove him to check his position against the satellite sensors—and he sighed. Gone, or down to three and all but one on the wrong side of the planet at the moment. They hadn’t had time to get the things into stationary orbits.

“Can’t triangulate without a triangle . . .”

The breeze took his voice along with it and rewarded him a moment later with an echo.

He laughed mirthlessly. Well, at least
that
ranging system worked. It was, alas, a system he’d never learned to use, though he’d been told that on certain worlds the experts could say a song across a snowy mountain range and tell, from the echoes, distance as well as the safety of an ice pack.

Ice pack
. Now there was a dangerous thought! Truth was that this world used to have an ice pack, but what it had now for all its trouble were two meteor-scarred polar regions and a star with so dangerously and preternaturally active a surface that it could be a candidate for a nova in a million years or so. His ship’s geologist had speculated that in the height of planetary winter—five hundred or so local days hence, when the planet was nearly a third more distant from its star—there might be enough cold to accumulate a water snow to some significant depth—say as deep as his boots—on the northern plains and cap.

Checking the magnetic compass for north he saw a nervously twittering display as the field fluctuated, and he wondered if there’d be another round of ghostly electric coronas lighting the night sky.

As he walked across the rocky ridge, anger built. Within historical record—perhaps as recently as two thousand Common Years—this world has been a candidate for open air colonization. In the meantime? In the meantime, the
sheriekas
conceived and mounted a bombardment of the inner system, setting robots to work in the outer debris clouds and targeting both the star and this world.

Kill. Destroy. Make life, human, animal, any—already improbable enough—impossible . . .

The
sheriekas
did this wherever they could, as if life itself was anathema. Overt signs of
sheriekas
action were an indication that a planet or a system held something worthwhile . . .

And so here was Jela—perhaps the first human to set foot on the planet, perhaps the last—trying to understand what was
here
that so needed destroying, what was
here
that the
sheriekas
hated enough to focus their considerable destructive energies upon.

It wasn’t useful to be angry at the enemy when the enemy wasn’t to hand. He sighed, called to mind the breathing exercises and exercised, dutifully. Eventually, he was rewarded with calm, and his pace smoothed out of the inefficient angry stride to a proper soldier’s ground-eating lope.

Suddenly, he walked in near darkness, then out again as the defile he’d entered widened. In time of snow or rain this would have been a dangerous place. It was as convenient a walkway as any, now that the plants were killed off or gone subsurface, now that the animals, if there had been any, were long extinct.

After some time he found himself more in the dark than otherwise, saw the start of a flickering glow in the sky to the north, and stopped his march to take stock. Underfoot was windblown silt. Soft enough to sleep on.

He ran through his ration list mentally, pulled out a night-pack, selected his water, and camped on the spot. Overhead the sky flickered green fire until well after he went to sleep.

THE FOOTING
had become treacherous and Jela half-regretted his decision to travel with light-pack. The dangle-cord he carried was barely three times his height and it might have been easier to get through the more canyon-like terrain with the long rope. On the other hand, he was moving faster than he would have with the full pack, and he’d have had no more rations anyway . . .

Now that he was below the ridges rather than walking them, he found the grit and breeze not quite so bad, though the occasional eddy of wind might still scour his face with its burden. Too, not being constantly in the direct rays of the local star helped, though that might be a problem again as it approached mid-day. For the moment, though, he was making time, and was in pretty good shape.

Rations now. Rations were becoming an issue. It was true that his rations were designed to let him work longer on less, and it was equally true that
he’d
been designed—or at least gene-selected—to get by on less food than most people ate, and to be more efficient in his use of water. Unfortunately, it was also true that he did require
some
food,
some
water,
some
sleep, and
some
shelter—or he, like most people in similarly deprived circumstances, would die.

Bad design, that dying bit, he thought—but no, that was what the
sheriekas
had thought to conquer—and perhaps had conquered. No one seemed to know that for sure. Meanwhile, he—Generalist Jela—had been designed with human care, and he approved of much of the design. He could see and hear better than average, for instance, his reaction times were fast and refined—and he was far stronger for his size than almost anyone.

It was this last bit of design work that had gotten his leg broken, despite it, too, being stronger than average. He just couldn’t hold the weight of six large men on it at once. He’d gone over that fight in his mind many times, and with several fighting instructors. He’d done everything right—just sometimes, no matter what, you were going to lose.

He was rambling again. Deliberately, he brought his attention back to the job at hand. The next moment or two would bring him to the mouth of the canyon and into the valley proper; soon he should have sight of the structures he’d spotted on his recon runs.

The possibility that they were flood control devices had been suggested by the ship’s geologists, as well as the idea that they were “cabinets” for some kind of energy generating stations that needed to be able to survive both flood and ice. Dams—for water conservation? Even the idea that they were the remains of housing had been suggested . . .

His stomach grumbled, protesting the lack of wake-up rations. He figured he’d be hungry for awhile. No reason to break that next pack open quite yet.

He slogged on, cap shading his eyes, watching for the first sign of the—

There! There was one!

It was silted in, of course, and beyond it another—but the form of it, the details of it, the stubs—

He ran—a hundred paces or so it was to the nearest—put his hand on it—

Laughed then, and shook his head.

And laughed some more, because he didn’t want to cry. . .

THE TREES
had been magnificent. Their crowns must have reached above the canyon rim in spots, and together they may have shaded the valley below from the direct light of the local star. An entire ecosystem had no doubt depended upon them. No wonder the ship’s geologists had thought them constructs from orbit . . .

What remained was still impressive. The base diameter of the downed trunk he touched was easily six or seven times his own height and he hesitated to guess how long a board might have been sawn from its length.

The shadow caught his attention then as light began filling the area in earnest.

It was time to move downstream. If there was water left at all, it would most likely be at the ancient headwaters—too far by days for him to reach—or downstream. Downstream, he might make in time for it to matter.

HE WALKED,
because he’d chosen to explore, and explore he would. At night, he stopped when his augmented vision blurred, camping where he stood. He went to short rations, cut them in half, and in half again, stinting on water as much as he dared. So far, the rescue transponder had guided no one to his position—friend or foe.

So, he walked, and he strove to be alert, spending part of the time analyzing his surroundings, part watching the sky, and part in an on-going argument with himself—an argument he was losing.

“Not going to do it, I bet. They can’t make me!”

“Will, can.”

“Won’t, can’t.”

The argument concerned the growing fashion among the newer troops of putting their ID markers on their face. Fashion was something he didn’t deal with all that much, and besides, he felt that a commander should be making these kinds of decisions, not a troop. And yet, he had to own it was convenient to be able to tell at a glance which unit, rank, and specialty defined a particular soldier.

“Shouldn’t!”

He’d said this loudly—definitively—just before Tree Number Sixty-four, and it was while using the base of that tree as shade—and checking the angle of its fall—that the position locator in his pocket chuckled briefly.

He grabbed the unit, watching the power-light—but there, that was silly. Unless things improved pretty soon the unit’s power would outlast him by quite some number of years. After all, it had been three days—four?—since he’d last had heard that sound . . .

Live now, the sensor showed him to be somewhat closer to the pre-marked goal than he had expected; the map roughed in by the original orbital photos showed that he’d managed to miss an early valley entrance—likely by refusing to walk quite as boldly as he might have into the teeth of the gritty breeze—and had thus saved himself a half-day or more of trudging down a much longer hillside.

The big question was becoming “saved” for what? There were no signs of life that was still alive; nor of water. The trees—

Maybe the trees
were
worth the walk, after all. There was a theory growing in his head—that he’d come in part looking for great works, and he’d found great works. In the days he’d been walking with the trees he’d found evidence of purpose far beyond the probability of happy accident.

For one thing, in places—not random places but specific kinds of places—the trees had fallen across the ancient watercourse, high ground to high ground, just where there was no marching forward to the ocean on that bank. They seemed to have preferred the left bank—which was generally wider, when it existed at all—and they sometimes seemed to have rested from their march and made a small grove, while at other times they’d hurried, stringing a long line of solitary trees.

Too, they were getting smaller. It saddened him, but the later trees . . . sigh.

Sloppy thinking. He didn’t have dated evidence. For all he factually knew, the first tree he had encountered was the youngest, not the eldest. And yet he persisted in believing that the trees had marched from the high ground down to the sea, and with purpose. And what other purpose could they have but to live—and by continuing to live fight the purpose of the
sheriekas
?

“As long as there is life in the Spiral Arm, especially intelligent, organized life, the
sheriekas
will not easily reach their goal!” The memory-voice rang in his ears, for the moment obscuring the sound of the wind.

That had been . . . who had it been, after all?

Song-woman.

Right.

Jela closed his eyes, saw the small troop of them standing on a hilltop like so many ancient savages, singing, singing, singing.

He’d been part of a survey team then, too, his very first, and he’d laughed at their belief that they were fighting some space-borne invader by standing there singing, singing in the light and long into the night.

In the morning, there had been three fewer of the singers, and word eventually came down from the frontier that three
sheriekas
world-eaters had simply vanished from tracking—gone, poof!

The timer on his arm went off. He reached for a water bulb . . . and stopped before his hand got close to the pocket. Not yet. He’d been waiting a little bit longer of late, and longer still if he could. There wasn’t a whole lot of water left and he’d stopped counting. That he was in the valley helped, since the cutting wind—though noisier—was much less in evidence here among the fallen trees at river height.
