We camp as the first lengthening of the shadows begins, gather some scrubby wood for our fire, pitch our tent. There is not much in the way of conversation. Sergeant is a crude, inarticulate man at best; Seeker is too tense and fretful to be pleasant company; Provisioner, who has grown burly and red-faced with the years, can be jovial enough after a drink or two, but he seems uncharacteristically moody and aloof tonight. So I am left to my own resources, and once we have finished our meal I walk out a short way into the night and stare, as I often do, at the glittering array of stars in this western sky of ours, wondering, as ever, whether each has its own collection of worlds, and whether those worlds are peopled, and what sort of lives the peoples of those worlds might lead. It is a perverse sort of amusement, I suppose: I who have spent half my life guarding a grim brick fort in this parched isolated outpost stare at the night sky and imagine the gleaming palaces and fragrant gardens of faraway worlds.

  We rise early, make a simple breakfast, ride on through a cutting wind toward those three far-off hills. This morning, though, the perspective changes quickly: suddenly the hills are much closer, and then they are upon us, and Seeker, excited now, guides us toward the pass between the southernmost hill and its neighbor. “I feel him just beyond!” he cries. For Seeker, the sense that he calls directionality is like a compass, pointing the way toward our foes. “Come! This is the way! Hurry! Hurry!”

  Nor has he led us wrongly this time. On the far side of the southernmost hill someone has built a little lean-to of twisted branches covered with a heaping of grass, no simple project in these stony ungenerous wastes. We draw our weapons and take up positions surrounding it, and Sergeant goes up to it and says, “You! Come out of there, and keep your hands in the air!”

  There is a sound of stirring from within. In a moment or two a man emerges.

  He has the classic enemy physiognomy: a short, stumpy body, sallow waxen skin, and heavy features with jutting cheekbones and icy blue eyes. At the sight of those eyes I feel an involuntary surge of anger, even hatred, for we of the Empire are a brown-eyed people and I have trained myself through many years to feel nothing but hostility for those whose eyes are blue.

  But these are not threatening eyes. Obviously the man had been asleep, and he is still making the journey back into wakefulness as he comes forth from his shelter, blinking, shaking his head. He is trembling, too. He is one man and we are four, and we have weapons drawn and he is unarmed, and he has been taken by surprise. It is an unfortunate way to start one’s day. I am amazed to find my anger giving way to something like pity.

  He is given little time to comprehend the gravity of his situation. “Bastard!” Sergeant says, and takes three strides forward. Swiftly he thrusts his knife into the man’s belly, withdraws it, strikes again, again.

  The blue eyes go wide with shock. I am shocked myself, in a different way, and the sudden cruel attack leaves me gasping with amazement.

  The stricken enemy staggers, clutches at his abdomen as though trying to hold back the torrent of blood, takes three or four tottering steps, and falls in a series of folding ripples. There is a convulsion or two, and then he is still, lying face downward.

  Sergeant kicks the entrance of the shelter open and peers within. “See if there’s anything useful in there,” he tells us.

  Still astounded, I say, “Why did you kill him so quickly?”

  “We came here to kill him.”

  “Perhaps. But he was unarmed. He probably would have given himself up peacefully.”

  “We came here to kill him,” Sergeant says again.

  “We might have interrogated him first, at least. That’s the usual procedure, isn’t it? Perhaps there are others of his kind somewhere close at hand.”

  “If there were any more of them around here,” Sergeant says scornfully, “Seeker would have told us, wouldn’t he have? Wouldn’t he have, Surveyor?”

  There is more that I would like to say, about how it might have been useful or at any rate interesting to discover why this man had chosen to make this risky pilgrimage to the edge of our territory. But there is no point in continuing the discussion, because Sergeant is too stupid to care what I have to say, and the man is already dead, besides.

  We knock the shelter apart and search it. Nothing much there: a few tools and weapons, a copper-plated religious emblem of the kind that our enemies worship, a portrait of a flat-faced blue-eyed woman who is, I suppose, the enemy’s wife or mother. It does not seem like the equipment of a spy. Even to an old soldier like me it is all very sad. He was a man like us, enemy though he was, and he died far from home. Yes, it has long been our task to kill these people before they can kill us. Certainly I have killed more than a few of them myself. But dying in battle is one thing; being slaughtered like a pig while still half asleep is something else again. Especially if your only purpose had been to surrender. Why else had this solitary man, this lonely and probably desperate man, crossed this unrelenting desert, if not to give himself up to us at the fort?

  I am softening with age, I suppose. Sergeant is right that it was our assignment to kill him: Captain had given us that order in the most explicit way. Bringing him back with us had never been part of the plan. We have no way of keeping prisoners at the fort. We have little enough food for ourselves, and guarding him would have posed a problem. He had had to die; his life was forfeit from the moment he ventured within the zone bordering on the fort. That he might have been lonely or desperate, that he had suffered in crossing this terrible desert and perhaps had hoped to win shelter at our fort, that he had had a wife or perhaps a mother whom he loved, all of that was irrelevant. It did not come as news to me that our enemies are human beings not all that different from us except in the color of their eyes and the texture of their skins. They are, nevertheless, our enemies. Long ago they set their hands against us in warfare, and until the day arrives when they put aside their dream of destroying what we of the Empire have built for ourselves, it is the duty of people like us to slay men like him. Sergeant had not been kind or gentle about it. But there is no kind or gentle way, really, to kill.

  The days that followed were extremely quiet ones. Without so much as a discussion of what had taken place in the desert we fell back into our routines: clean and polish this and that, repair whatever needs repair and still can be repaired, take our turns working in the fields alongside the river, wade in that shallow stream in quest of water-pigs for our table, tend the vats where we store the mash that becomes our beer, and so on, so forth, day in, day out. Of course I read a good deal, also. I have ever been a man for reading.

  We have nineteen books; all the others have been read to pieces, or their bindings have fallen apart in the dry air, or the volumes have simply been misplaced somewhere about the fort and never recovered. I have read all nineteen again and again, even though five of them are technical manuals covering areas that never were part of my skills and which are irrelevant now anyway. (There is no point in knowing how to repair our vehicles when the last of our fuel supply was exhausted five years ago.) One of my favorite books is The Saga of the Kings, which I have known since childhood, the familiar account, probably wholly mythical, of the Empire’s early history, the great charismatic leaders who built it, their heroic deeds, their inordinately long lifespans. There is a religious text too that I value, though I have grave doubts about the existence of the gods. But for me the choice volume of our library is the one called The Register of Strange Things Beyond the Ranges, a thousand-year-old account of the natural wonders to be found in the outer reaches of the Empire’s great expanse. Only half the book remains to us now—perhaps one of my comrades ripped pages out to use as kindling, once upon a time—but I cherish that half, and read it constantly, even though I know it virtually by heart by this time.

  Wendrit likes me to read to her. How much of what she hears she is capable of understanding, I have no idea: she is a simple soul, as all her people are. But I love the way she turns her big violet-hued eyes
toward me as I read, and sits in total attention.

  I read to her of the Gate of Ghosts, telling her of the customs shed there that spectral phantoms guard: “Ten men go out, nine men return.” I read to her of the Stones of Shao, two flat-sided slabs flanking a main highway that on a certain day every ten years would come crashing together, crushing any wayfarers who happened to be passing through just then, and of the bronze Pillars of King Mai, which hold the two stones by an incantation that forbids them ever to move again. I read to her of the Mountain of a Thousand Eyes, the granite face of which is pockmarked with glossy onyx boulders that gleam down upon passersby like stern black eyes. I tell her of the Forest of Cinnamon, and of the Grotto of Dreams, and of the Place of Galloping Clouds. Were such places real, or simply the fantasies of some ancient spinner of tall tales? How would I know, I who spent my childhood and youth at the capital, and have passed the rest of my years here at this remote desert fort, where there is nothing to be seen but sandy yellow soil, and twisted shrubs, and little scuttering scorpions that run before our feet? But the strange places described in The Register of Strange Things Beyond the Ranges have grown more real to me in these latter days than the capital itself, which has become in my mind a mere handful of vague and fragmentary impressions. So I read with conviction, and Wendrit listens in awe, and when I weary of the wonders of the Register I put it aside and take her hand and lead her to my bed, and caress her soft pale-green skin and kiss the tips of her small round breasts, and so we pass another night.

  In those quiet days that followed our foray I thought often of the man Sergeant had killed. In the days when we fought battles here I killed without compunction, five, ten, twenty men at a time, not exactly taking pleasure in it but certainly feeling no guilt. But the killing in those days was done at a decent distance, with rifles or heavy guns, for we still had ammunition then and our rifles and guns were still in good repair. It was necessary now in our forays against the occasional spies who approached the fort to kill with spears or knives, and to kill at close range feels less like a deed of warfare to me and more like murder.

  My mind went back easily to those battles of yesteryear: the sound of the sentry’s alarm, the first view of the dark line of enemy troops on the horizon, the rush to gather our weapons and start our vehicles. And out we would race through the portcullis to repel the invaders, rushing to take up our primary defensive formation, then advancing in even ranks that filled the entire gap in the hills, so that when the enemy entered that deadly funnel we could fall upon them and slaughter them. It was the same thing every time. They came; we responded; they perished. How far they must have traveled to meet their dismal deaths in our dreary desert! None of us had any real idea how far away the country of the enemy actually was, but we knew it had to be a great distance to the north and west, just as our own country is a great distance to the south and east. The frontier that our own outpost defends lies on the midpoint between one desert and another. Behind us is the almost infinite terrain of sparse settlements that eventually culminates in the glorious cities of the Empire. Before us are equally interminable wastes that gives way, eventually, to the enemy homeland itself. For one nation to attack the other, it must send its armies far across an uncharted and unfriendly nothingness. Which our enemy was willing to do, the gods only knew why, and again and again their armies came, and again and again we destroyed them in the fine frenzy of battle. That was a long time ago. We were not much more than boys then. But finally the marching armies came no more, and the only enemies we had to deal with were those few infrequent spies or perhaps stragglers whom Seeker pinpointed for us, and whom we went out and slew at close range with our knives and spears, looking into their frosty blue eyes as we robbed them of their lives.

  Seeker is in a bad way. He can go from one day to the next without saying a word. He still heads up to his watchtowers almost every morning, but he returns from his vigils in a black cloak of gloom and moves through our midst in complete silence. We know better than to approach him at such times, because, though he is a man of no great size and strength, he can break out in savage fury sometimes when his depressions are intruded upon. So we let him be; but as the days pass and his mood grows ever darker, we fear some sort of explosion.

  One afternoon I saw him speaking with Captain out on the rooftop terrace. It appeared that Captain had initiated the conversation, and that Seeker was answering Captain’s questions with the greatest reluctance, staring down at his boots as he spoke. But then Captain said something that caused Seeker to react with surprising animation, looking up, gesticulating. Captain shook his head. Seeker pounded his fists together. Captain made a gesture of dismissal and walked away.

  What they were saying to each other was beyond all guessing. And beyond all asking, too, for if anyone is more opaque than Seeker, it is Captain, and while it is at least possible at certain times to ask Seeker what is on his mind, making such an inquiry of Captain is inconceivable.

  In recent days Seeker has taken to drinking with us after dinner. That is a new thing for him. He has always disliked drinking. He says he despises the stuff we make that we call beer and wine and brandy. That is reasonable enough, because we make our beer from the niggardly sour grain of a weed that grows by the river, and we wrest our thin wine and our rough brandy from the bitter gray fruits of a different weed, and they are pitiful products indeed to anyone who remembers the foaming beers of the capital and the sweet vintages of our finest wine-producing districts. But we have long since exhausted the supplies of such things that we brought with us, and, of course, no replenishments from home ever come, and, since in this somber landscape there is comfort to be had from drinking, we drink what we can make. Not Seeker, no. Not until this week.

  Now he drinks, though, showing no sign of pleasure, but often extending his glass for another round. And at last one night when he has come back with his glass more than once, he breaks his long silence.

  “They are all gone,” he says, in a voice like the tolling of a cracked bell.

  “Who are?” Provisioner asks. “The scorpions? I saw three scorpions only yesterday.” Provisioner is well along in his cups, as usual. His reddened, jowly face creases in a broad toothy smile, as if he has uttered the cleverest of witticisms.

  “The enemy,” says Seeker. “The one we killed—he was the last one. There’s nobody left. Do you know how empty I feel, going up to the towers to listen, and hearing nothing? As if I’ve been hollowed out inside. Can you understand what sort of feeling that is? Can you? No, of course you can’t. What would any of you know?”

  He stares at us in agony. “The silence…the silence….”

  Nobody seems to know how quite to respond to that, so we say nothing. And Seeker helps himself to yet another jigger of brandy, and full measure at that. This is alarming. The sight of Seeker drinking like this is as strange as the sight of a torrential downpour of rain would be.

  Engineer, who is probably the calmest and most reasonable of us, says, “Ah, man, can you not be a bit patient? I know you want to do your task. But more of them will come. Sooner or later, there’ll be another, and another after that. Two weeks, three, six, who knows? But they’ll come. You’ve been through spells like this before.”

  “No. This is different,” says Seeker sullenly. “But what would you know?”

  “Easy,” Engineer says, laying his strong hand across the back of Seeker’s frail wrist. “Go easy, man. What do you mean, ‘this is different?’”

  Carefully, making a visible effort at self-control, Seeker says, “All the other times when we’ve gone several weeks between incursions, I’ve always felt a low inner hum, a kind of subliminal static, a barely perceptible mental pressure, that tells me there are at least a few enemies out there somewhere, a hundred miles away, five hundred, a thousand. It’s just a kind of quiet buzz. It doesn’t give me any directionality. But it’s there, and sooner or later the signal becomes stronger, and then I know that a couple of them are getting clos
e to us, and then I get directionality and I can lead us to them, and we go out and kill them. It’s been that way for years, ever since the real battles stopped. But now I don’t get anything. Not a thing. It’s absolutely silent in my head. Which means that either I’ve lost my power entirely, or else there aren’t any enemies left within a thousand miles or more.”

  “And which is it that you think is so?”

  Seeker scans us all with a haggard look. “That there are no enemies out there any more. Which means that it is pointless to remain here. We should pack up, go home, make some sort of new lives for ourselves within the Empire itself. And yet we have to stay, in case they come. I must stay, because this is the only task that I know how to perform. What sort of new life could I make for myself back there? I never had a life. This is my life. So my choice is to stay here to no purpose, performing a task that does not need to be performed any longer, or to return home to no existence. Do you see my predicament?” He is shivering. He reaches for the brandy, pours yet another drink with a trembling hand, hastily downs it, coughs, shudders, lets his head drop to the tabletop. We can hear him sobbing.

  That night marks the beginning of the debate among us. Seeker’s breakdown has brought into the open something that has been on my own mind for some weeks now, and which Armorer, Weaponsmaster, Quartermaster, and even dull-witted Sergeant have been pondering also, each in his own very different way.

  The fact is unanswerable that the frequency of enemy incursions has lessened greatly in the past two years, and when they do come, every five or six or ten weeks apart, they no longer come in bands of a dozen or so, but in twos or threes. This last man whom Sergeant slew by the three little hills had come alone. Armorer has voiced quite openly his notion that just as our own numbers have dwindled to next to nothing over the years, the enemy confronting us in this desert must have suffered great attrition too, and, like us, has had no reinforcement from the home country, so that only a handful of our foes remain—or, perhaps, as Seeker now believes, none at all. If that is true, says Armorer, who is a wry and practical man, why do we not close up shop and seek some new occupation for ourselves in some happier region of the Empire?
