He too was reared by the torturers, I think. He too was sent forth to Thrax. He too fled Thrax, and though he did not carry the Claw of the Conciliator, he must have been drawn to the fighting in the north - no doubt he hoped to escape the archon by hiding himself among the army. How he encountered the Autarch there I cannot say; but encounter him he did, and so, even as I, he (who in the final sense was and is myself) became Autarch in turn and sailed beyond the candles of night. Then those who walk the corridors walked back to the time when he was young, and my own story - as I have given it here in so many pages - began.

The second thing is this. He was not returned to his own time but became himself a walker of the corridors. I know now the identity of the man called the Head of Day, and why Hildegrin, who was too near, perished when we met, and why the witches fled. I know too in whose mausoleum I tarried as a child, that little building of stone with its rose, its fountain, and its flying ship all graven. I have disturbed my own tomb, and now I go to lie in it.

When Drotte, Roche, Eata, and I returned to the Citadel, I received urgent messages from Father Inire and from the House Absolute, and yet 1 lingered. I asked the castellan for a map. After much searching he produced one, large and old, cracked in many places. It showed the curtain wall whole, but the names of the towers were not the names I knew - or that the castellan knew, for that matter - and there were towers on that map that are not in the Citadel, and towers in the Citadel that were not on that map.

I ordered a flier then, and for half a day soared among the towers. No doubt I saw the place I sought many times, but if so I did not recognize it.

At last, with a bright and unfailing lamp, I went down into our oubliette once more, down flight after flight of steps until I had reached the lowest level. What is it, I wonder, that has given so great a power to preserve the past to underground places? One of the bowls in which I had carried soup to Triskele was there still. (Triskele, who had stirred back to life beneath my hand two years before I bore the Claw.) I followed Triskele's footprints once more, as I had when still an apprentice, to the forgotten opening, and from there my own into the dark maze of tunnels.

Now in the steady light of my lamp I saw where I had lost the track, running straight on when Triskele had turned aside. I was tempted then to follow him instead of myself, so that I might see where he had emerged, and in that way perhaps discover who it was who had befriended him and to whom he used to return after greeting me, sometimes, in the byways of the Citadel. Possibly when I come back to Urth I shall do so, if indeed I do come back.

But once again, I did not turn aside. I followed the boy-man I had been, down a straight corridor floored with mud and pierced at rare intervals with forbidding vents and doors. The Severian I pursued wore ill-fitting shoes with run-down heels and worn soles; when I turned and flashed my light behind me, I observed that though the Severian who pursued him had excellent boots, his steps were of unequal length and the toe of one foot dragged at each. I thought, One Severian had good boots, the other good legs. And I laughed to myself, wondering who should come here in afteryears, and whether he would guess that the same feet left both tracks.

To what use these tunnels were once put, I cannot say. Several times I saw stairs that had once descended farther still, but always they led to dark, calm water. I found a skeleton, its bones scattered by the running feet of Severian, but it was only a skeleton, and told me nothing. In places there was writing on the walls, writing in faded orange or sturdy black; but it was in a character I could not read, as unintelligible as the scrawlings of the rats in Master Ultan's library. A few of the rooms into which I looked held walls in which there had once ticked a thousand or more clocks of various kinds, and though all were dead now, their chimes silenced and their hands corroded at hours that would never come again, I thought them good omens for one who sought the Atrium of Time.

And at last I found it. The little spot of sunshine was just as I had remembered it. No doubt I acted foolishly, but I extinguished my lamp and stood for a moment in the dark, looking at it. All was silence, and its bright, uneven square seemed at least as mysterious as it had before.

I had feared I would have difficulty in squeezing through its narrow crevice, but if the present Severian was somewhat larger of bone, he was also leaner, so that when I had worked my shoulders through the rest followed easily enough.

The snow I recalled was gone, but a chill had come into the air to say that it would soon return. A few dead leaves, which must have been carried in some updraft very high indeed, had come to rest here among the dying roses. The tilted dials still cast their crazy shadows, useless as the dead clocks beneath them, though not so unmoving. The carven animals stared at them, unwinking still.

I crossed to the door and tapped on it. The timorous old woman who had served us appeared, and I, stepping into that musty room in which I had warmed myself before, told her to bring Valeria to me. She hurried away, but before she was out of sight, something had wakened in the time-worn walls, its disembodied voices, hundred-tongued, demanding that Valeria report to some antiquely titled personage who I realized with a start must be myself.

Here my pen shall halt, reader, though I do not. I have carried you from gate to gate - from the locked and fog-shrouded gate of the necropolis of Nessus to that cloud-racked gate we call the sky, the gate that shall lead me, as I hope, beyond the nearer stars.

My pen halts, though I do not. Reader, you will walk no more with me. It is time we both take up our lives.

To this account, I, Severian the Lame, Autarch, do set my hand in what shall be called the last year of the old sun.
