"This flows swiftly south until it meets the flood of Gyoll, which then runs more slowly to Nessus, and at last to the southern sea. No fugitive can be found in the maze of Nessus who does not wish it, for there are streets and courts and tenements there without number, and all the faces of all lands are seen a hundred times over. If you could go there, dressed as you are now, without friends or money, would you do so?"

She nodded, one pale hand at her throat.

"There is no barrier to boats yet at the Capulus; Abdiesus knows he need not fear any attack made against the current there until midsummer. But you will have to shoot the arches, and you may drown. Even if you reach Nessus, you will have to work for your bread - wash for others, perhaps, or cook."

"I can dress hair and sew. Severian, I have heard that sometimes, as the last and most terrible torture, you tell your prisoner she will be freed. If that is what you're doing to me now, I beg you to stop. You've gone far enough."

"A caloyer does that, or some other religious functionary. No client would believe us. But I want to be certain there will be no foolishness of returning to your home or seeking a pardon from the archon."

"I am a fool," Cyriaca said. "But no. Not even such a fool as I am would do that, I swear."

We skirted the water's edge until we came to the stairs where the sentries stood to admit the archon's guests, and the little, brightly hued pleasure boats were moored. I told one of the soldiers we were going to try the river, and asked if we would have any difficulty hiring rowers to take us back upstream. He said we might leave the boat at the Capulus if we wished, and return in a fiacre. When he turned away to resume his conversation with his comrade, I pretended to inspect the boats, and slipped the painter of the one farthest from the torches of the guard post.

Dorcas said, "And so now you are going north as a fugitive, and I have taken your money."

"I won't need much, and I will get more." I stood up.

"Take back half at least." When I shook my head, she said, "Then take back two chrisos. I can whore, if worst comes to worst, or steal."

"If you steal, your hand will be struck off. And it is better that I strike off hands for my dinner than that you give your hands for yours."

I started to go, but she sprang out of bed and held my cloak. "Be careful, Severian. There is something - Hethor called it a salamander

 - loose in the city. Whatever it is, it burns its victims." I told her I had much more to fear from the archon's soldiers than from the salamander, and left before she could say more. But as I toiled up a narrow street on the western bank that my boatmen had assured me would lead to the cliff top, I wondered if I would not have more to fear from the cold of the mountains, and their wild beasts, than from either. I wondered too about Hethor, and how he had followed me so far into the north, and why. But more than I thought on any of those things, I thought about Dorcas, and what she had been to me, and I to her. It was to be a long time before I would so much as glimpse her again, and I believe that in some way I sensed that. Just as when I had first left the Citadel I had pulled up my hood so that the passersby might not observe my smiles, so now I hid my face to conceal the tears running down my cheeks. I had seen the reservoir that supplied the Vincula twice before by day, but never by night. It had appeared small then, a rectangular pond no larger than the foundation of a house and no deeper than a grave. Under the waning moon it seemed almost a lake, and might have been as deep as the cistern below the Bell Tower. It lay no more than a hundred paces from the wall that defended the western margin of Thrax. There were towers on that wall - one quite near the reservoir - and no doubt the garrisons had by that time been ordered to apprehend me if I tried to escape from the city. At intervals, as I had walked along the cliff, I had glimpsed the sentries who patrolled the wall; their lances were unkindled, but their crested helms showed against the stars, and sometimes faintly caught the light.

Now I crouched, looking out over the city and relying on my fuligin cloak and hood to deceive their eyes. The barred iron portcullises of the arches of the Capulus had been lowered - I could detect the roiling of the Acis where it battered against them. That removed all doubt: Cyriaca had been stopped - or more probably, simply seen and reported. Abdiesus might or might not make strenuous efforts to capture her; it seemed most probable to me that he would allow her to vanish, and so avoid drawing attention to her. But he would surely apprehend me if he could, and execute me as the traitor to his rule that I was.

From the water I looked to water again, from the rushing Acis to the still reservoir. I had the word for the sluice gate, and I used it. The ancient mechanism ground up as though moved by phantom slaves, and then the still waters rushed too, rushed faster than the raging Acis at the Capulus. Far below, the prisoners would hear their roar, and those nearest the entrance would see the white foam of the flood. In a moment those who stood would be up to their ankles in water, and those who had slept would be scrambling to their feet. In another moment, all would be waist deep; but they were chained in their places, and the weaker would be supported by the stronger -

none, I hoped, would drown. The clavigers at the entrance would leave their posts and hurry up the steep trail to the cliff top to see who had tampered with the reservoir there.

And as the last water drained away, I heard the stones dislodged by their feet rattling down the slope. I closed the sluice gate again and lowered myself into the slimy and nearly vertical passage that the water had just traversed. Here my progress would have been far easier if I had not been carrying Terminus Est. To brace my back against one side of that crooked, chimneylike pipe, I had to unsling her; yet I could not spare a hand to hold her. I put her baldric around my neck, let her blade and sheath hang down, and managed her weight as well as I could. Twice I slipped, but each time I was saved by a turn of the narrowing sluice; and at last, after so long a time that I was certain the clavigers would have returned, I saw the gleam of red torchlight and drew forth the Claw.

I was never to see it flame so bright again. It was blinding, and I carrying it upraised down the long tunnel of the Vincula, could only wonder that my hand was not reduced to ashes. No prisoner, I think, saw me. The Claw fascinated them as a lantern by night does the deer of the forest; they stood motionless, their mouths open, their raddled, bearded faces uplifted, their shadows behind them as sharp as silhouettes cut in metal and dark as fuligin.

At the very end of the tunnel, where the water ran out into the long, sloping sewer that carried it below the Capulus, were the weakest and most diseased prisoners; and it was there that I saw most clearly the strength the Claw lent them all. Men and women who had not stood straight in the memory of the oldest claviger now seemed tall and strong. I waved in salute to them, though I am sure none of them observed it. Then I put the Claw of the Conciliator back into its little pouch, and we were plunged into a night beside which the night of the surface of Urth would be day.

The rush of water had swept the sewer clean, and it was easier to descend than the sluice had been, for though it was narrower, it was less steep, and I could crawl rapidly down headforemost. There was a grill at the bottom; but as I had noted on one of my inspection tours, it was nearly rusted through.

CHAPTER THIRTEEN - INTO THE MOUNTAINS

SPRING HAD ENDED and summer begun when I crept away from the Capulus in the gray light, but even so it was never warm in the high lands except when the sun was near the zenith. Yet I did not dare to go into the valleys where the villages huddled, and all day I walked up, into the mountains, with my cloak furled across one shoulder to make it look as nearly as possible like the garment of an eclectic. I also dismounted the blade of Terminus Est and reassembled it without the guard, so that the sheathed sword seen from a distance would have the appearance of a staff. By noon the ground was all of stone, and so uneven that I did as much climbing as walking. Twice I saw the glint of armor far below me, and looking down beheld little parties of dimarchi cantering down trails most men could scarcely have persuaded themselves to walk, their scarlet military capes billowing behind them. I found no edible plants and sighted no game other than high soaring birds of prey. Had I seen any, I would have had no chance of taking it with my sword, and I possessed no other weapon.

All that sounds desperate enough, but the truth was that I was thrilled by the mountain views, the vast panorama of the empire of air. As children we have no appreciation of scenery because, having not yet stored similar scenes in our imagination, with their attendant emotions and circumstances, we perceive it without psychic depth. I now looked at the cloud-crowned summits with my view of Nessus from the nose cone of our Matachin Tower and my view of Thrax from the battlements of Acies Castle before me as well, and miserable though I was, I was ready to faint with pleasure. That night I spent huddled in the lee of a naked rock. I had not eaten since I had changed clothes in the Vincula, which now seemed weeks, if not years, before. In actuality, it had been only months since I had smuggled a worn kitchen knife to poor Thecla, and seen her blood seeping, a groping worm of crimson, from beneath her cell door.

I had chosen my stone well, at least. It blocked the wind, so that as long as I remained behind it I might almost have rested in the quiet, frigid air of some ice cave. A step or two to either side brought me into the full blast, so that I was chilled to the bone in a single frosty moment.

I slept for about a watch, I think, without any dreams that outlived my sleep, then woke with the impression - which was not a dream, but the sort of foundationless knowledge or pseudoknowledge that comes to us at times when we are weary and fearful - that Hethor was leaning over me. I seemed to feel his breath, stinking and icy cold, upon my face; his eyes, no longer dull, blazed into mine. When I was fully awake, I saw that the points of light I had taken for their pupils were in fact two stars, large and very bright in the thin, clean air.

I tried to sleep again, closing my eyes and forcing myself to remember the warmest and most comfortable places I had known: the journeyman's quarters I had been given in our tower, which had then seemed so palatial with their privacy and soft blankets after the apprentices' dormitory; the bed I had once shared with Baldanders, into which his broad back had projected heat like a stove's; Thecla's apartments in the House Absolute; the snug room in Saltus where I had lodged with Jonas.

Nothing helped. I could not sleep again, and yet I dared not to try to walk farther for fear that I would fall over some precipice in the dark. I spent the remainder of the night staring at the stars; it was the first time I had ever really experienced the majesty of the constellations, of which Master Malrubius had taught us when I was the smallest of the apprentices. How strange it is that the sky, which by day is a stationary ground on which the clouds are seen to move, by night becomes the backdrop for Urth's own motion, so that we feel her rolling beneath us as a sailor feels the running of the tide. That night the sense of this slow turning was so strong that I was almost giddy with its long, continued sweep.

Strong too was the feeling that the sky was a bottomless pit into which the universe might drop forever. I had heard people say that when they looked at the stars too long they grew terrified by the sensation of being drawn away. My own fear -  and I felt fear - was not centered on the remote suns, but rather on the yawning void; and at times I grew so frightened that I gripped the rock with my freezing fingers, for it seemed to me that I must fall off Urth. No doubt everyone feels some touch of this, since it is said that there exists no climate so mild that people will consent to sleep in unroofed houses.

I have already described how I woke thinking that Hethor's face (I suppose because Hethor had been much in my mind since I talked to Dorcas) was staring into mine, yet discovered when I opened my eyes that the face retained no detail except the two bright stars that had been its own. So it was with me at first when I tried to pick out the constellations, whose names I had often read, though I had only the most imperfect idea of the part of the sky in which each might be found. At first all the stars seemed a featureless mass of lights, however beautiful, like the sparks that fly upward from a fire. Soon, of course, I began to see that some were brighter than others, and that their colors were by no means uniform. Then, quite unexpectedly, when I had been staring at them for a long time, the shape of a peryton seemed to spring out as distinctly as if the bird's whole body had been powdered with the dust ground from diamonds. In a moment it was gone again, but it soon returned, and with it other shapes, some corresponding to constellations of which I had heard, others that were, I am afraid, entirely of my own imagining. An amphisbaena, or snake with a head at either end, was particularly distinct.

When these celestial animals burst into view, I was awed by their beauty. But when they became so strongly evident (as they quickly did) that I could no longer dismiss them by an act of will, I began to feel as frightened of them as I was of falling into that midnight abyss over which they writhed; yet this was not a simple physical and instinctive fear like the other, but rather a sort of philosophical horror at the thought of a cosmos in which rude pictures of beasts and monsters had been painted with flaming suns.

After I covered my head with my cloak, which I was forced to do lest I go mad, I fell to thinking of the worlds that circled those suns. All of us know they exist, many being mere endless plains of rock, others spheres of ice or of tindery hills where lava rivers flow, as is alleged of Abaddon; but many others being worlds more or less fair, and inhabited by creatures either descended from the human stock or at least not wholly different from ourselves. At first I thought of green skies, blue grass, and all the rest of the childish exotica apt to inflict the mind that conceives of other than Urthly worlds. But in time I tired of those puerile ideas, and began in their place to think of societies and ways of thought wholly different from our own, worlds in which all the people, knowing themselves descended from a single pair of colonists, treated one another as brothers and sisters, worlds where there was no currency but honor, so that everyone worked in order that he might be entitled to associate himself with some man or woman who had saved the community, worlds in which the long war between mankind and the beasts was pursued no more. With these thoughts came a hundred or more new ones - how justice might be meted out when all loved all, for example; how a beggar who retained nothing but his humanity might beg for honor, and the ways in which people who would kill no sentient animal might be shod and fed.
