But though there may be nothing to see, that does not mean that there is nothing out there. The entire universe is out there. If we could see it while we are traveling across the special space that is heaven we would find it flattened and curved, so that we had the illusion of viewing everything at once, all the far-flung galaxies back to the beginning of time. This is the Great Open, the totality of the continuum. Our external screens show it to us in simulated form, because we need occasional assurance that it is there.

  A starship rides along the mighty lines of force which cross that immense void like the lines of the compass rose on an ancient mariner’s map. When we starwalk, we ride those same lines, and we are held by them, sealed fast to the ship that is carrying us onward through heaven. We seem to step forth into space; we seem to look down on the ship, on the stars, on all the worlds of heaven. For the moment we become little starships flying along beside the great one that is our mother. It is magic; it is illusion; but it is magic that so closely approaches what we perceive as reality that there is no way to measure the difference, which means that in effect there is no difference.

  “Ready?” I asked Vox.

  “Absolutely.”

  Still I hesitated.

  “Are you sure?”

  “Go on,” she said impatiently. “Do it!”

  I put the jack to my spine myself. Banquo did the matching of impedances. If he were going to discover the passenger I carried, this would be the moment. But he showed no sign that anything was amiss. He queried me; I gave him the signal to proceed; there was a moment of sharp warmth at the back of my neck as my neural matrix, and Vox’s traveling with it, rushed out through Banquo and hurtled downward toward its merger with the soul of the ship.

  We were seized and drawn in and engulfed by the vast force that is the ship. As the coils of the engine caught us we were spun around and around, hurled from vector to vector, mercilessly stretched, distended by an unimaginable flux. And then there was a brightness all about us, a brightness that cried out in heaven with a mighty clamor. We were outside the ship. We were starwalking.

  “Oh,” she said. A little soft cry, a muted gasp of wonder.

  The blazing mantle of the ship lay upon the darkness of heaven like a white shadow. That great cone of cold fiery light reached far out in front of us, arching awesomely toward heaven’s vault, and behind us it extended beyond the limits of our sight. The slender tapering outline of the ship was clearly visible within it, the needle and its Eye, all ten kilometers of it easily apparent to us in a single glance.

  And there were the stars. And there were the worlds of heaven.

  The effect of the stardrive is to collapse the dimensions, each one in upon the other. Thus inordinate spaces are diminished and the galaxy may be spanned by human voyagers. There is no logic, no linearity of sequence, to heaven as it appears to our eyes. Wherever we look we see the universe bent back upon itself, revealing its entirety in an infinite series of infinite segments of itself. Any sector of stars contains all stars. Any demarcation of time encompasses all of time past and time to come. What we behold is altogether beyond our understanding, which is exactly as it should be; for what we are given, when we look through the Eye of the ship at the naked heavens, is a god’s-eye view of the universe. And we are not gods.

  “What are we seeing?” Vox murmured within me.

  I tried to tell her. I showed her how to define her relative position so there would be an up and a down for her, a backward, a forward, a flow of time and event from beginning to end. I pointed out the arbitrary coordinate axes by which we locate ourselves in this fundamentally incomprehensible arena. I found known stars for her, and known worlds, and showed them to her.

  She understood nothing. She was entirely lost.

  I told her that there was no shame in that.

  I told her that I had been just as bewildered, when I was undergoing my training in the simulator. That everyone was; and that no one, not even if he spent a thousand years aboard the starships that plied the routes of heaven, could ever come to anything more than a set of crude equivalents and approximations of understanding what starwalking shows us. Attaining actual understanding itself is beyond the best of us.

  I could feel her struggling to encompass the impact of all that rose and wheeled and soared before us. Her mind was agile, though still only half-formed, and I sensed her working out her own system of explanations and assumptions, her analogies, her equivalencies. I gave her no more help. It was best for her to do these things by herself; and in any case I had no more help to give.

  I had my own astonishment and bewilderment to deal with, on this my second starwalk in heaven.

  Once more I looked down upon the myriad worlds turning in their orbits. I could see them easily, the little bright globes rotating in the huge night of the Great Open: red worlds, blue worlds, green ones, some turning their full faces to me, some showing mere slivers of a crescent. How they cleaved to their appointed tracks! How they clung to their parent stars!

  I remembered that other time, only a few virtual days before, when I had felt such compassion for them, such sorrow. Knowing that they were condemned forever to follow the same path about the same star, a hopeless bondage, a meaningless retracing of a perpetual route. In their own eyes they might be footloose wanderers, but to me they had seemed the most pitiful of slaves. And so I had grieved for the worlds of heaven; but now, to my surprise, I felt no pity, only a kind of love. There was no reason to be sad for them. They were what they were, and there was a supreme rightness in those fixed orbits and their obedient movements along them. They were content with being what they were. If they were loosed even a moment from that bondage, such chaos would arise in the universe as could never be contained. Those circling worlds are the foundations upon which all else is built; they know that and they take pride in it; they are loyal to their tasks and we must honor them for their devotion to their duty. And with honor comes love.

  This must be Vox speaking within me, I told myself.

  I had never thought such thoughts. Love the planets in their orbits? What kind of notion was that? Perhaps no stranger than my earlier notion of pitying them because they weren’t starships; but that thought had arisen from the spontaneous depths of my own spirit and it had seemed to make a kind of sense to me. Now it had given way to a wholly other view.

  I loved the worlds that moved before me and yet did not move, in the great night of heaven.

  I loved the strange fugitive girl within me who beheld those worlds and loved them for their immobility.

  I felt her seize me now, taking me impatiently onward, outward, into the depths of heaven. She understood now; she knew how it was done. And she was far more daring than ever I would have allowed me to be. Together we walked the stars. Not only walked but plunged and swooped and soared, traveling among them like gods. Their hot breath singed us. Their throbbing brightness thundered at us. Their serene movements boomed a mighty music at us. On and on we went, hand in hand, Vox leading, I letting her draw me, deeper and deeper into the shining abyss that was the universe. Until at last we halted, floating in mid-cosmos, the ship nowhere to be seen, only the two of us surrounded by a shield of suns.

  In that moment a sweeping ecstasy filled my soul. I felt all eternity within my grasp. No, that puts it the wrong way around and makes it seem that I was seized by delusions of imperial grandeur, which was not at all the case. What I felt was myself within the grasp of all eternity, enfolded in the loving embrace of a complete and perfect cosmos in which nothing was out of place, or ever could be.

  It is this that we go starwalking to attain. This sense of belonging, this sense of being contained in the divine perfection of the universe.

  When it comes, there is no telling what effect it will have; but inner change is what it usually brings. I had come away from my first starwalk unaware of any transformation; but within three days I had impulsively opened myself to a wandering phantom, violating not only regulations
but the nature of my own character as I understood it. I have always, as I think I have said, been an intensely private man. Even though I had given Vox refuge, I had been relieved and grateful that her mind and mine had remained separate entities within our shared brain.

  Now I did what I could to break down whatever boundary remained between us.

  I hadn’t let her know anything, so far, of my life before going to heaven. I had met her occasional questions with coy evasions, with half-truths, with blunt refusals. It was the way I had always been with everyone, a habit of secrecy, an unwillingness to reveal myself. I had been even more secretive, perhaps, with Vox than with all the others, because of the very closeness of her mind to mine. As though I feared that by giving her any interior knowledge of me I was opening the way for her to take me over entirely, to absorb me into her own vigorous, undisciplined soul.

  But now I offered my past to her in a joyous rush. We began to make our way slowly backward from that apocalyptic place at the center of everything; and as we hovered on the breast of the Great Open, drifting between the darkness and the brilliance of the light that the ship created, I told her everything about myself that I had been holding back.

  I suppose they were mere trivial things, though to me they were all so highly charged with meaning. I told her the name of my home planet. I let her see it, the sea the color of lead, the sky the color of smoke. I showed her the sparse and scrubby gray headlands behind our house, where I would go running for hours by myself, a tall slender boy pounding tirelessly across the crackling sands as though demons were pursuing him.

  I showed her everything: the somber child, the troubled youth, the wary, overcautious young man. The playmates who remained forever strangers, the friends whose voices were drowned in hollow babbling echoes, the lovers whose love seemed without substance or meaning. I told her of my feeling that I was the only one alive in the world, that everyone about me was some sort of artificial being full of gears and wires. Or that the world was only a flat colorless dream in which I somehow had become trapped, but from which I would eventually awaken into the true world of light and color and richness of texture. Or that I might not be human at all, but had been abandoned in the human galaxy by creatures of another form entirely, who would return for me some day far in the future.

  I was lighthearted as I told her these things, and she received them lightly. She knew them for what they were—not symptoms of madness, but only the bleak fantasies of a lonely child, seeking to make sense out of an incomprehensible universe in which he felt himself to be a stranger and afraid.

  “But you escaped,” she said. “You found a place where you belonged!”

  “Yes,” I said. “I escaped.”

  And I told her of the day when I had seen a sudden light in the sky. My first thought then had been that my true parents had come back for me; my second, that it was some comet passing by. That light was a starship of heaven that had come to worldward in our system. And as I looked upward through the darkness on that day long ago, straining to catch a glimpse of the shoreships that were going up to it bearing cargo and passengers to be taken from our world to some unknowable place at the other end of the galaxy, I realized that that starship was my true home. I realized that the Service was my destiny.

  And so it came to pass, I said, that I left my world behind, and my name, and my life, such as it had been, to enter the company of those who sail between the stars. I let her know that this was my first voyage, explaining that it is the peculiar custom of the Service to test all new officers by placing them in command at once. She asked me if I had found happiness here; and I said, quickly, Yes, I had, and then I said a moment later, Not yet, not yet, but I see at least the possibility of it.

  She was quiet for a time. We watched the worlds turning and the stars like blazing spikes of color racing toward their far-off destinations, and the fiery white light of the ship itself streaming in the firmament as if it were the blood of some alien god. The thought came to me of all that I was risking by hiding her like this within me. I brushed it aside. This was neither the place nor the moment for doubt or fear or misgiving.

  Then she said, “I’m glad you told me all that, Adam.”

  “Yes. I am too.”

  “I could feel it from the start, what sort of person you were. But I needed to hear it in your own words, your own thoughts. It’s just like I’ve been saying. You and I, we’re two of a kind. Square pegs in a world of round holes. You ran away to the Service and I ran away to a new life in somebody else’s body.”

  I realized that Vox wasn’t speaking of my body, but of the new one that waited for her on Cul-de-Sac.

  And I realized too that there was one thing about herself that she had never shared with me, which was the nature of the flaw in her old body that had caused her to discard it. If I knew her more fully, I thought, I could love her more deeply: imperfections and all, which is the way of love. But she had shied away from telling me that, and I had never pressed her on it. Now, out here under the cool gleam of heaven, surely we had moved into a place of total trust, of complete union of soul.

  I said, “Let me see you, Vox.”

  “See me? How could you—”

  “Give me an image of yourself. You’re too abstract for me this way. Vox. A voice. Only a voice. You talk to me, you live within me, and I still don’t have the slightest idea what you look like.”

  “That’s how I want it to be.”

  “Won’t you show me how you look?”

  “I won’t look like anything. I’m a matrix. I’m nothing but electricity.”

  “I understand that. I mean how you looked before. Your old self, the one you left behind on Kansas Four.”

  She made no reply.

  I thought she was hesitating, deciding; but some time went by, and still I heard nothing from her. What came from her was silence, only silence, a silence that had crashed down between us like a steel curtain.

  “Vox?”

  Nothing.

  Where was she hiding? What had I done?

  “What’s the matter? Is it the thing I asked you?”

  No answer.

  “It’s all right, Vox. Forget about it. It isn’t important at all. You don’t have to show me anything you don’t want to show me.”

  Nothing. Silence.

  “Vox? Vox?”

  The worlds and stars wheeled in chaos before me. The light of the ship roared up and down the spectrum from end to end. In growing panic I sought for her and found no trace of her presence within me. Nothing. Nothing.

  “Are you all right?” came another voice. Banquo, from inside the ship. “I’m getting some pretty wild signals. You’d better come in. You’ve been out there long enough as it is.”

  Vox was gone. I had crossed some uncrossable boundary and I had frightened her away.

  Numbly I gave Banquo the signal, and he brought me back inside.

  13.

  Alone, I made my way upward level by level through the darkness and mystery of the ship, toward the Eye. The crash of silence went on and on, like the falling of some colossal wave on an endless shore. I missed Vox terribly. I had never known such complete solitude as I felt now. I had not realized how accustomed I had become to her being there, nor what impact her leaving would have on me. In just those few days of giving her sanctuary, it had somehow come to seem to me that to house two souls within one brain was the normal condition of mankind, and that to be alone in one’s skull as I was now was a shameful thing.

  As I neared the place where Crew Deck narrows into the curve of the Eye a slender figure stepped without warning from the shadows.

  “Captain.”

  My mind was full of the loss of Vox and he caught me unawares. I jumped back, badly startled.

  “For the love of God, man!”

  “It’s just me. Bulgar. Don’t be so scared, Captain. It’s only Bulgar.”

  “Let me be,” I said, and brusquely beckoned him away.

  “No. Wai
t, Captain. Please, wait.”

  He clutched at my arm, holding me as I tried to go. I halted and turned toward him, trembling with anger and surprise.

  Bulgar, Roacher’s jackmate, was a gentle, soft-voiced little man, wide-mouthed, olive-skinned, with huge sad eyes. He and Roacher had sailed the skies of Heaven together since before I was born. They complemented each other. Where Roacher was small and hard, like fruit that has been left to dry in the sun for a hundred years, his jackmate Bulgar was small and tender, with a plump, succulent look about him. Together they seemed complete, an unassailable whole: I could readily imagine them lying together in their bunk, each jacked to the other, one person in two bodies, linked more intimately even than Vox and I had been.

  With an effort I recovered my poise. Tightly I said, “What is it, Bulgar?”

  “Can we talk a minute, Captain?”

  “We are talking. What do you want with me?”

  “That loose matrix, sir.”

  My reaction must have been stronger than he was expecting. His eyes went wide and he took a step or two back from me.

  Moistening his lips, he said, “We were wondering, Captain—wondering how the search is going—whether you had any idea where the matrix might be—”

  I said stiffly, “Who’s we, Bulgar?”

  “The men. Roacher. Me. Some of the others. Mainly Roacher, sir.”

  “Ah. So Roacher wants to know where the matrix is.”

  The little man moved closer. I saw him staring deep into me as though searching for Vox behind the mask of my carefully expressionless face. Did he know? Did they all? I wanted to cry out, She’s not there any more, she’s gone, she left me, she ran off into space. But apparently what was troubling Roacher and his shipmates was something other than the possibility that Vox had taken refuge with me.
