WHEN I HEARD the footsteps, I had risen and drawn my sword, and I waited in a shadow for what seemed a watch at least, though it was no doubt much less. Twice more I heard them, quick and soft, yet somehow suggestive of a large man — a powerful man hurrying, almost running, light-footed and athletic.

Here the stars were in all their glory; as bright as they must be seen by the sailors whose ports they are, when they go aloft to spread the golden gauze that would wrap a continent. I could see the motionless guardsmen almost as if by day, and the buildings around me, bathed in the many-colored lights of ten thousand suns. We think with horror of the frozen plains of Dis, the outermost companion of our sun — but of how many suns are we the outermost companion? To the people of Dis (if such exist) it is all one long, starry night.

Several times, standing there under the stars, I nearly slept; and at the borders of sleep I worried about the boy, thinking that I had probably awakened him when I rose and wondering where I should find food for him when the sun could be seen again. After such thoughts, the memory of his death would come to my mind as night had come to the mountain, a wave of blackness and despair. I knew then how Dorcas had felt when Jolenta died. There had been no sexual play between the boy and me, as I believe there had at some time been between Dorcas and Jolenta; but then it had never been their fleshly love that had aroused my jealousy. The depth of my feeling for the boy had been as great as Dorcas’s for Jolenta, surely (and surely greater far than Jolenta’s for Dorcas). If Dorcas had known of it, she would have been as jealous as I had sometimes been, I thought, if only she had loved me as I had loved her.

At last, when I heard the footsteps no longer, I concealed myself as well as I could and lay down and slept. I half expected I would not wake from that sleep, or that I would wake with a knife at my throat, but no such thing happened. Dreaming of water, I slept well past the dawn and woke alone, cold and stiff in every limb.

I cared nothing then for the secret of the footsteps, or the guardsmen, or the ring, or for anything else in that accursed place. My only wish was to leave it, and as quickly as possible; and I was delighted — though I could not have explained why — when I found that I would not have to repass the circular building on my way to the northwestern side of the mountain.

There have been many times when I have felt I have gone mad, for I have had many great adventures, and the greatest adventures are those that act most strongly upon our minds. So it was then. A man, larger than I and far broader of shoulder, stepped from between the feet of a cataphract, and it was as though one of the monstrous constellations of the night sky had fallen to Urth and clothed itself in the flesh of humankind. For the man had two heads, like an ogre in some forgotten tale in The Wonders of Urth and Sky.

Instinctively, I put my hand on the sword hilt at my shoulder. One of the heads laughed; I think it was the only laughter I was ever to hear at the baring of that great blade.

“Why are you alarmed?” he called. “I see you are as well equipped as I am. What is your friend’s name?”

Even in my surprise, I admired his boldness. “She is Terminus Est,” I said, and I turned the sword so he could see the writing on the steel.

“ ‘This is the place of parting.’ Very good. Very good indeed, and particularly good that it should be read here and now, because this time will truly be a line between old and new such as the world has not seen. My own friend’s name is Piaton, which I fear means nothing much. He is an inferior servant to that you have, though perhaps a better steed.”

Hearing its name, the other head opened wide its eyes, which had been half closed, and rolled them. Its mouth moved as though to speak, but no sound emerged. I thought it a species of idiot.

“But now you may put up your weapon. As you see, I am unarmed, though already beheaded, and in any case, I mean you no hurt.”

He raised his hands as he spoke, and turned to one side and then the other, so that I might see that he was entirely naked, something that was already clear enough.

I asked, “Are you perhaps the son of the dead man I saw in the round building back there?”

I had sheathed Terminus Est as I spoke, and he took a step nearer, saying, “Not at all. I am the man himself.”

Dorcas rose in my thoughts as if through the brown waters of the Lake of Birds, and I felt again her dead hand clutch mine. Before I knew that I was speaking, I blurted, “I restored you to life?”

“Say rather that your coming awakened me. You thought me dead when I was only dry. I drank, and as you see, I live again. To drink is to live, to be bathed in water is to have a new birth.”

“If what you tell me is true, it is wonderful. But I am too much in need of water myself to think much about it now. You say that you have drunk, and the way you say it implies at least that you’re friendly toward me. Prove it, please. I haven’t eaten or drunk for a long time.”

The head that spoke smiled. “You have the most marvelous way of falling in with whatever I plan — there is an appropriateness about you, even to your clothing, that I find delightful. I was just about to suggest that we go where there is food and drink in plenty. Follow me.”

At that time, I think I would have followed anyone who promised me water anywhere. Since then I have tried to convince myself that I went out of curiosity, or because I hoped to learn the secret of the great cataphracts; but when I recall those moments and search my mind as it was then, I find nothing other than despair and thirst. The waterfall above Casdoe’s house wove its silver columns before my eyes, and I remembered the Vatic Fountain of the House Absolute, and the rush of water from the cliff top in Thrax when I opened the sluice gate to flood the Vincula.

The two-headed man walked before me as if he were confident I would follow him, and equally confident that I would not attack him. When we rounded a corner, I realized for the first time that I had not been, as I had thought, on one of the radiating streets that led to the circular building. It stood before us now. A door — though it was not the one through which little Severian and I had passed — was open as before, and we entered.

“Here,” the head that spoke said. “Get in.”

The thing toward which he gestured was like a boat, and padded everywhere within as the nenuphar boat in the Autarch’s garden had been; yet it floated not on water but in air. When I touched the gunwale, the boat rocked and bobbed beneath my hand, though the motion was almost too small to be seen. I said, “This must be a flyer. I’ve never seen one so close before.”

“If a flyer were a swallow, this would be — I don’t know — a sparrow, perhaps. Or a mole, or the toy bird that children strike with paddles to make it fly back and forth between them. Courtesy, I fear, demands that you enter first. I assure you there is no danger.”

Still, I hung back. There seemed something so mysterious about that vessel that for the moment I could not bring myself to set foot in it. I said, “I come from Nessus and from the eastern bank of Gyoll, and we were taught there that the place of honor in any craft is to be the last to enter and the first to leave.”

“Precisely,” the head that spoke replied, and before I realized what was happening, the two-headed man seized me about the waist and tossed me into the boat as I might have tossed the boy. It dipped and rolled under the impact of my body, and a moment later yawed violently as the two-headed man sprang in beside me. “You didn’t think, I hope, that you were to take precedence over me?”
