We approached that part of the city where the Citadel stands -

which is southern but not the southernmost - under sail and by day. I watched the sun-gilt eastern bank with great care, and had the captain land me on those slimy steps where I had once swum and fought. I hoped to pass through the necropolis gate and so enter the Citadel through the breach in the curtain wall that was near the Matachin Tower; but the gate was closed and locked, and no convenient party of volunteers arrived to admit me. Thus I was forced instead to walk many chains along the margin of the necropolis, and several more along the curtain wall to the barbican. There I encountered a numerous guard who carried me before their officer, who, when I told him I was a torturer, supposed me to be one of those wretches that, most often at the onset of winter, seek to gain admission to the guild. He decided (very properly, had he been correct) to have me whipped; and to prevent it I was forced to break the thumbs of two of his men, and then demand while I held him in the way called the kitten and ball that he take me to his superior, the castellan.

I admit I was somewhat awed at the thought of this official, whom I had seldom so much as seen in all the years I had been an apprentice in the fortress he commanded. I found him an old soldier, silver-haired and as lame as I. The officer stammered out his accusations while I stood by: I had assaulted and insulted (not true) his person, maimed two of his men, and so on. When he had finished, the castellan looked from me to him and back again, dismissed him, and offered me a seat.

"You are unarmed," he said. His voice was hoarse but soft, as though he had strained it shouting commands.

I admitted that I was.

"But you have seen fighting, and you have been in the jungle north of the mountains, where no battle has been since they turned our flank by crossing the Uroboros."

"That's true," I said. "But how can you know?"

"That wound in your thigh came from one of their spears. I've seen enough to recognize them. The beam flashed up through the muscle, reflected by the bone. You might have been up a tree and been stuck by a hastarus on the ground, I suppose, but the most likely thing is that you were mounted and charging infantry. Not a cataphract, or they wouldn't have got you so easily. The demilances?"

"Only the light irregulars."

"You'll have to tell me about that later, because you're a city man from your accent, and they're eclectics and suchlike for the most part. You have a double scar on your foot too, white and clean, with the marks half a span apart. That was a blood bat's bite, and they don't come that large except in the true jungle at the waist of the world. How did you get there?"

"Our flier crashed. I was taken prisoner."

"And escaped?"

In a moment more I would have been forced to talk of Agia and the green man, and of my journey from the jungle to the mouth of Gyoll, and those were high matters which I did not wish to disclose thus casually. Instead of an answer, I pronounced the words of authority applicable to the Citadel and its castellan. Because he was lame, I would have had him remain seated if I could; but he sprang to his feet and saluted, then dropped to his knees to kiss my hand. He was thus, though he could not have known it, the first to pay me homage, a distinction that entitles him to a private audience once a year - an audience he has not yet requested and perhaps never will.

For me to proceed now, clothed as I was, was impossible. The old castellan would have died of a stroke had I demanded it, and he was so concerned for my safety that any incognito would have been accompanied by at least a platoon of lurking halberdiers. I soon found myself arrayed in lapis lazuli jazerant, cothurni, and a stephane, the whole set off by an ebony baculus and a voluminous damassin cape embroidered with rotting pearls. All these things were inde-scribably ancient, having been taken from a store preserved from the period when the Citadel was the residence of the autarchs.

Thus in place of entering our tower, as I had intended, in the same cloak in which I had left it, I returned as an unrecognizable being in ceremonial fancy dress, skeletally thin, lame, and hideously scarred. It was with this appearance that I entered Master Palaemon's study, and I am certain I must almost have frightened him to death, since he had been told only a few moments before that the Autarch was in the Citadel and wished to converse with him.

He seemed to me to have aged a great deal while I was gone. Perhaps it was simply that I recalled him not as he was when I was exiled, but as I had seen him in our little classroom when I was a boy. Still, I like to think he was concerned for me, and it is not really so unlikely that he was: I had always been his best pupil and his favorite; it was his vote, beyond doubt, that had countered Master Gurloes's and saved my life; he had given me his sword. But whether he had worried much or little, his face seemed more deeply lined than it had been; and his scant hair, which I had thought gray, was now of that yellow hue seen in old ivory. He knelt and kissed my fingers, and was more than a little surprised when I helped him to rise and told him to seat himself behind his table again.

"You are too kind, Autarch," he said. Then, using an old formula,

"Your mercy extends from sun to Sun."

"Do you not recall us?"

"Were you confined here?" He peered at me through the curious arrangement of lenses that alone permitted him to see at all, and I decided that his vision, exhausted long before I was born on the faded ink of the records of the guild, must have deteriorated further.

"You have suffered torment, I see. But it is too crude, I hope, for our work."

"It was not your doing," I said, touching the scars on my cheek.

"Nevertheless, we were confined for a time in the oubliette beneath this tower." He sighed - an old man's shallow breath - and looked down at the gray litter of his papers. When he spoke I could not hear the words, and had to ask him to repeat them.

"It has come," he said. "I knew it would, but I hoped to be dead and forgotten. Will you dismiss us, Autarch? Or put us to some other task?"

"We have not yet decided what we will do with you and the guild you serve."

"It will not avail. If I offend you, Autarch, I ask your indulgence for my age... but still it will not avail. You will find in the end that you require men to do what we do. You may call it healing, if you wish. That has been done often. Or ritual, that has been done too. But you will find the thing itself grows more terrible in its disguise. Will you imprison those undeserving of death? You will find them a mighty army in chains. You will discover that you hold prisoners whose escape would be a catastrophe, and that you need servants who will wreak justice on those who have caused scores to die in agony. Who else will do that?"

"No one will wreak such justice as you. You say our mercy extends from sun to Sun, and we hope it is so. By our mercy we will grant even the foulest a quick death. Not because we pity them, but because it is intolerable that good men should spend a lifetime dispensing pain."

His head came up and the lenses flashed. For the only time in all the years I had known him, I was able to see the youth he had been. "It must be done by good men. You are badly advised, Autarch! What is intolerable is that it should be done by bad men." I smiled. His face, as I had seen it then, had recalled something I had thrust from my mind months before. It was that this guild was my family, and all the home I should ever have. I would never find a friend in the world if I could not find friends here. "Between us, Master," I told him, "we have decided it should not be done at all." He did not reply, and I saw from his expression that he had not even heard what I had said. He had been listening instead to my voice, and doubt and joy flickered over his worn, old face like shadow and firelight.

"Yes," I said. "It is Severian," and while he was struggling to regain possession of himself, I went to the door and got my sabretache, which I had ordered one of the officers of my guard to bring. I had wrapped it in what had been my fuligin guild cloak, now faded to mere rusty black. Spreading the cloak over Master Palaemon's table, I opened the sabretache and poured out its contents. "This is all we have brought back," I said.

He smiled as he used to in the schoolroom when he had caught me out in some minor matter. "That and the throne? Will you tell me about it?"

And so I did. It took a long while, and more than once my protectors rapped at the door to ascertain that I was unharmed, and at last I had a meal brought in to us; and when the pheasant was mere bones and the cakes were eaten and the wine drunk, we were still talking. It was then that I conceived the idea that has at last borne fruit in this record of my life. I had originally intended to begin it at the day I left our tower and to end it when I returned. But I soon saw that though such a construction would indeed supply the symmetry so valued by artists, it would be impossible for anyone to understand my adventures without knowing something of my adolescence. In the same way, some elements of my story would remain incomplete if I did not extend it (as I propose to do) a few days beyond my return. Perhaps I have contrived for someone The Book of Gold. Indeed, it may be that all my wanderings have been no more than a contrivance of the librarians to recruit their numbers; but perhaps even that is too much to hope.

CHAPTER THIRTY-FOUR - THE KEY TO THE UNIVERSE

When he had heard everything, Master Palaemon went to my little heap of possessions and took up the grip, pommel, and silver guard that were all that remained of Terminus Est. "She was a good sword," he said. "Nearly I gave you your death, but she was a good sword."

"We were always proud to bear her, and never found reason to complain of her."

He sighed, and the breath seemed to catch in his throat. "She is gone. It is the blade that is the sword, not the sword furniture. The guild will preserve these somewhere, with your cloak and sabretache, because they have belonged to you. When you and I have been dead for centuries, old men like me will point them out to the apprentices. It's a pity we haven't the blade too. I used her for many years before you came to the guild, and never thought she would be destroyed fighting some diabolical weapon." He put down the opal pommel and frowned at me. "What's troubling you? I've seen men wince less when their eyes were torn out."

"There are many kinds of diabolical weapons, as you call them, that steel cannot withstand. We saw something of them when we were in Orithyia. And there are tens of thousands of our soldiers there holding them off with firework lances and javelins, and swords less well forged than Terminus Est. They succeed in so far as they do because the energy weapons of the Ascians are not numerous, and they are few because the Ascians lack the sources of power needed to produce them. What will happen if Urth is granted a New Sun?

Won't the Ascians be better able to use its energy than we can?"

"Perhaps that may be," Master Palaemon acknowledged.

"We have been thinking with the autarchs who have gone before us

 - our guild brothers, as it were, in a new guild. Master Malrubius said that only our predecessor has dared the test in modern times. When we touch the minds of the others, we often find that they have refused it because they felt our enemies, who have retained so much more of the ancient sciences, would gain a greater advantage. Is it not possible they were right?"

Master Palaemon thought a long time before he answered. "I cannot say. You believe me wise because I taught you once, but I have not been north, as you have. You have seen armies of Ascians, and I have never seen one. You flatter me by asking my opinion. Still -

from all you've said, they are rigid, cast hard in their ways. I would guess that very few among them think much."

I shrugged. "That is true in any aggregate, Master. But as you say, it is possibly more true among them. And what you call their rigidity is terrible - a deadness that surpasses belief. Individually they seem men and women, but together they are like a machine of wood and stone."

Master Palaemon rose and went to the port and looked out upon the thronging towers. "We are too rigid here," he said. "Too rigid in our guild, too rigid in the Citadel. It tells me a great deal that you, who were educated here, saw them as you did; they must be inflexible indeed. I think it may be that despite their science, which may amount to less than you suppose, the people of the Commonwealth will be better able to turn new circumstances to their benefit."

"We are not flexible or inflexible," I said. "Except for an unusually good memory, we are only an ordinary man."

"No, no!" Master Palaemon struck his table, and again the lenses flashed. "You are an extraordinary man in an ordinary time. When you were a little apprentice, I beat you once or twice - you will recall that, I know. But even when I beat you, I knew you would become an extraordinary personage, the greatest master our guild would ever have. And you will be a master. Even if you destroy our guild, we will elect you!"

"We have already told you we mean to reform the guild, not destroy it. We're not even sure we're competent to do that. You respect us because we've moved to the highest place. But we reached it by chance, and know it. Our predecessor reached it by chance too, and the minds he brought to us, which we touch only faintly even now, are not, with one or two exceptions, those of genius. Most are only common men and women, sailors and artisans, farmwives and wantons. Most of the rest are eccentric second-rate scholars of the sort Thecla used to laugh at."

"You have not just moved into the highest place," Master Palaemon said, "you have become it. You are the state."

"We are not. The state is everyone else - you, the castellan, those officers outside. We are the people, the Commonwealth." I had not known it myself until I spoke.

I picked up the brown book. "We are going to keep this. It was one of the good things, like your sword. The writing of books shall be encouraged again. There are no pockets in these clothes; but perhaps it will do good if we are seen to carry it when we leave."
