I said, "I understand."

"Twice before members of the guild have been dispatched to outlying towns, though whether those were such cases as this the chronicles do not say. Nevertheless, they furnish a precedent now, and an escape from the maze. You are to go to Thrax, Severian. I have prepared a letter that will introduce you to the archon and his magistrates. It describes you as highly skilled in our mystery. For such a place, it will not be a falsehood." I nodded, being already resigned to what I was to do. Yet while I sat there, maintaining the expressionless face of a journeyman whose only will is to obey, a new shame burned in me. Though it was not so hot as the one for the disgrace I had brought upon the guild, still it was fresher, and hurt the more because I had not yet grown accustomed to the sickness of it as I had the other. It was this: that I was glad to go - that my feet already longed for the feel of grass, my eyes for strange sights, my lungs for the new, clear air of far, unmanned places.

I asked Master Palaemon where the town of Thrax might be.

"Down Gyoll," he said. "Near the sea." Then he stopped as old men will, and said, "No, no, what am I thinking of? Up Gyoll, of course," and for me hundreds of leagues of marching waves, and the sand, and the seabirds' crying all faded away. Master Palaemon took a map from his cabinet and unrolled it for me, bending over it until the lens by which he saw such things nearly touched the parchment. "There," he said, and showed me a dot on the margin of the young river, at the lower cataracts. "If you had funds you might travel by boat. As it is, you must walk."

"I understand," I said, and though I remembered the thin piece of gold Vodalus had given me, safe in its hiding place, I knew I could not take advantage of whatever wealth it might represent. It was the guild's will to cast me out with no more money than a young journeyman might be expected to possess, and for prudence's sake as well as honor's, so I must go.

Yet I knew it was unfair. If I had not glimpsed the woman with the heart-shaped face and earned that small gold coin, it is more than possible I would never have carried the knife to Thecla and forfeited my place in the guild. In a sense, that coin had bought my life.

Very well - I would leave my old life behind me . . .

"Severian!" Master Palaemon exclaimed. "You are not listening to me. You were never an inattentive pupil in our classes."

"I'm sorry. I was thinking about a great many things."

"No doubt." For the first time he really smiled, and for an instant looked his old self, the Master Palaemon of my boyhood. "Yet I was giving you such good advice for your journey. Now you must do without it, but doubtless you would have forgotten every-thing anyway. You know of the roads?"

"I know they must not be used. Nothing more."

"The Autarch Maruthas closed them. That was when I was your age. Travel encouraged sedition, and he wished goods to enter and leave the city by the river, where they might be easily taxed. The law has remained in force since, and there is a redoubt, so I've heard, every fifty leagues. Still the roads remain. Though they are in poor repair, it is said some use them by night."

"I see," I said. Closed or not, the roads might make for an easier passage than traveling across the countryside as the law demanded.

"I doubt you do. I mean to warn you against them. They are patrolled by uhlans under orders to kill anyone found upon them, and since they have permission to loot the bodies of those they slay, they are not much inclined to ask excuses."

"I understand," I told him, and in private wondered how he came to know so much of travel.

"Good. The day is half spent now. If you like, you may sleep here tonight and depart in the morning."

"Sleep in my cell, you mean."

He nodded. Though I knew he could scarcely see my face, I felt that something in him was studying me.

"I will leave now, then." I tried to think of what I would have to do before I turned my back on our tower forever; nothing came to me, yet it seemed there must surely be something. "May I have a watch in which to prepare? When the time is up, I will go."

"That's easily granted. But before you leave, I want you to return here - I have something to give you. Will you do it?"

"Of course, Master, if you want me to."

"And Severian, be careful. There are many in the guild who are your friends who wish this had never happened. But there are others who feel you have betrayed our trust and deserve agony and death."

"Thank you, Master," I said. "The second group is correct." My few possessions were already in my cell. I bundled them together and found the whole bundle so small I could put it in the sabretache hanging from my belt. Moved by love, and regret for what had been, I went to Thecla's cell. It was empty still. Her blood had been scrubbed from the floor, but a wide, dark spot of blood-rust had etched the metal. Her clothing was gone, and her cosmetics. The four books I had carried to her a year before remained, stacked with others on the littIe table. I could not resist the temptation to take one; there were so many in the library that they would never miss a single volume. My hand had stretched forth before I realized I did not know which to choose. The book of heraldry was the most beautiful, but it was too large by far to carry about the country. The book of theology was the smallest of all, but the brown book was hardly larger. In the end it was that I took, with its tales from vanished worlds.

I climbed the stair of our tower then, past the storeroom to the gun room where the siege pieces lounged in cradles of pure force. Then higher still to the room of the glass roof, with its gray screens and strangely contorted chairs, and up a slender ladder until I stood on the slippery panes themselves, where my presence scattered blackbirds across the sky like flecks of soot and our fuligin pennon streamed and snapped from the staff over my head.

Below me the Old Yard seemed small and even cramped, but infinitely comfortable and homey. The breach in the curtain wall was greater than I had ever realized, though to either side of it the Red Tower and the Bear Tower still stood proud and strong. Nearest our own, the witches' tower was slender, dark, and tall; for a moment the wind blew a snatch of their wild laughter to me and I felt the old fear, though we of the torturers have always been on the most friendly terms with the witches, our sisters.

Beyond the wall, the great necropolis rolled down the long slope toward Gyoll, whose waters I could glimpse between the half-rotted buildings on its banks. Across the flood of the river the rounded dome of the khan seemed no more than a pebble, the city about it an expanse of many-colored sand trodden by the master torturers of old.

I saw a caique, with high, sharp prow and stem, and a bellying sail, making south with the dark current; and against my will I followed it for a time - to the delta and the swamps, and at last to the flashing sea where that great beast Abaia, carried from the farther shores of the universe in anteglacial days, wallows until the moment comes for him and his kind to devour the continents. Then I abandoned all thoughts of the south and her ice-choked sea and turned north to the mountains and the rising of the river. For a long time (I do not know how long, though the sun seemed in a new place when I took notice of its position again) I looked to the north. The mountains I could see with my mind's eye, but not with the body's: only the rolling expanse of the city with its million roofs. And to tell the truth, the great silver columns of the Keep and its surrounding spires blocked half my view. Yet I cared nothing for them, and indeed hardly saw them. North lay the House Absolute and the cataracts, and Thrax, City of Windowless Rooms. North lay the wide pampas, a hundred trackless forests, and the rotting jungles at the waist of the world. When I had thought on all those things until I was half mad, I came down to Master Palaemon's study again and told him I was ready to depart.
