It was cold and silent. Not a birdsound. Not an insect, though there were flowers enough in the open brush. Then the sun rose and so did I, setting off into the depths of the trees, going east but one-third south.

At first there was a morning breeze, but then that died, and the leaves hung absolutely still. Birds were rare, and when I saw any they were as if asleep in high branches, motionless. No small animals moved underfoot, and I wondered if this were the secret of Ku Kuei-- that nothing but plants lived here.

I could not see the sun, and so marked my direction by noting the trees that went in a line, correcting now and then. East and one-third south, I said again and again, trying not to hear it in the woman's voice-- why did I grieve for her, whom I did not know?

I walked for hours and hours, it seemed, and still it was only morning from the vague direction of the brightest light, where I supposed the sun must be. Paths ran left and right, but I followed again the voice of the old woman in my memory, saying, "Follow no paths."

I became hungry. I chewed on mutton. I found berries and ate them, but not the white ones.

At last my legs were so weary I couldn't set one in front of the other, and yet it was still day. I didn't understand my tiredness. In my training I had often been required to walk briskly from sunrise to sunset, until I could do it with little strain. Was there, then, some element in the forest air, some drug that weakened me? Or had the healing of all my recent wounds taken more from me than I expected?

I didn't know. I set down the pack beside a tree and slept without waking, long and hard.

So long that when I awoke it was daylight again, and I got up and pushed on.

Again a day of walking, then weariness while the sun was still high. This time I forced myself to go on, farther and farther, until I became a machine. I was alert enough to avoid entangling roots, to pick my way through thick places, to scramble over rocks, to slide carefully down the slopes of hollows and ravines, then clamber up the other side, but I was so numb with the effort just to stay awake that I wan't conscious of any of this, not really; an obstacle was forgotten the moment it was out of view. I felt as if I had been walking for days, and yet the sun was still high.

At first my weariness in so short a time made me feel a deep dread, that the complex of symptoms that marked a radical regenerative included a kind of general dystrophy-- but that couldn't be it, for I had found the strength to go on and on, hadn't I? I wasn't weakening, for surely I had covered some ground, at least. But perhaps rads were plagued with the sudden onset of bouts of almost uncontrollable sleepiness. Yet I was controlling it, wasn't I? And the rads in the pens, while they moved with the languor of despair, did not seem to sleep more often than other men, or at least no one ever said they did.

Then I had a thought that comforted me a little-- that the strange thing that was happening to me might not be a product of the condition of my own body, but rather might arise from the mysterious forest of Ku Kuei. Couldn't it be that the forests exuded some chemical that caused weariness? Or perhaps only the illusion of weariness. Or perhaps a whole complex of debilitating drugs in the air, causing hallucinations, distorting my sense of time, making me long to sleep with as much desperation as a man longs for water after three days without a drink.

That would explain why Ku Kuei had become such a feared and hated place. What if a man could wander in here and find his sense of time so distorted that he thought he had wandered miles in only a few minutes? Overcome with weariness, he might sleep twenty-four hours, then rise again, walk a few more meters, and fall down thinking he had done a day's labor. In only a short time the cumulative effect of all these chemicals could become fatal, either directly, by poisoning the man, or indirectly, by causing him to sleep until he dies of dehydration.

No wonder there were so few wild animals here. Perhaps a few birds acclimated to the poisonous air, some insects whose brains were too small even to be affected. But this would explain why nothing was heard from the Family of Ku Kuei almost from the hour they entered this wood three thousand years before.

Now here I was, caught up in the same natural defenses of this forest, and just as unlikely to win my way to freedom. My sentence had been death after all, not just exile. My flesh would be consumed by the bacteria and small insects of the forest floor; my bones would bleach and, after decades, crumble. I would then become part of the planet we called Treason, contributing to it the only metal that this soil would ever hold, the metal of men's souls. Was mine a soft and yielding element? Or would I be a hard place in the forest floor? Would roots soak up from me a metal that would lend vigor to their massive trunks?

These were my thoughts as I struggled to keep myself awake. For a time I think I even dreamed as I walked on, imagining myself to be one of a thousand trees marching forth to do combat with the dangerous black soldiers of Nkumai. And such was my madness that I even saw myself waving vast branches to sweep the swordsmen of Mueller from their feet, then grinding them into powder with my irresistible roots.

I came, to myself again, and thought more soberly-- though perhaps just as madly-- of what this poisonous forest might imply. It made me realize that in three thousand years of life on this world, all we of Mueller had ever thought about was how to get away, how to earn such vast quantities of iron that we might someday build a spaceship and escape. Other Families had spent their efforts trying to convince their Ambassador that they had repented of their ancestors' rebelliousness and wished to be returned from exile-- after all, they said in a thousand different missives, we are but the eightieth great grandchildren of those who once threatened your pleasant Republic. But all such wheedling letters were returned torn to shreds. Whoever was on the other end of the Ambassador, controlling it, had not learned forgiveness in three thousand years. It made me wonder if perhaps our ancestors' crimes were not in fact far more terrible than they claimed. After all, the only histories we possessed told their version of what happened, and in their accounts they were completely innocent. But aren't all monstrous criminals innocent in their own eyes? Don't all their victims somehow deserve to die, in their imagination, at least?

Why in all these years had we kept our gaze starward, hoping to escape this world, and so learned almost nothing of the secrets that it held? Before we came it had been studied only enough to learn two things: First, that it was habitable-- that, small as it was, Treason was massive enough to maintain us at about a third the gravity of the world where humans had evolved, so we would be strong, could run bounding across the prairies and among the giant trees; and the basic chemicals of life were close enough to ours that while we couldn't profitably eat the native animals, we and our animals could eat enough of the native plants to sustain ourselves, so sending us here was truly exile, and not a sentence of death. And, second, that so little metal was close enough to the surface that it wasn't even worth trying to extract it. It was a worthless world. A world that did not contain within it the material we could use to build a ladder outward to the stars.

But was it truly worthless, just because it couldn't let us build starships? This world was one of the rare ones that had given rise to life. Did we even understand why life arose here at all? Was it really enough to know that we could eat the plant life? Had we no curiosity about the differences between the native life and the chemistry of our own bodies? We had learned enough about ourselves to create monsters like me, but we hadn't learned enough about this world to truly say we lived here. Yet on the eastern border of Mueller there was a place where the very trees had learned enough about us to make a lone wanderer die of dreams beneath their shadow.
