utensils, such as kettles and pails, but most were completely empty, revealing no signs of life or use at all.
After I emerged from one of these caves, I was surprised to see my tarn across the pit, his head tilted to one side, as if puzzled. He then reached his beak out to an apparently blank wall and withdrew it, repeating this three or four times, and then began to walk back and forth, snapping his wings impatiently.
I raced across the pit. I began to examine the wall with fierce closeness. I scrutinized every inch and ran my hands carefully over every portion of its smooth surface. Nothing was revealed to my eyes or to my touch, but there was the almost imperceptible odor of tarn spoor.
For several minutes I examined the blank wall, sure that it held the secret of Marlenus's entrance into the city. Then, in frustration, I backed slowly away, hoping to see some lever or perhaps some suspicious crevice higher in the escarpment, something that might play its role in opening the passage I was sure lay hidden somewhere behind that seemingly solid mass of stone. Yet no lever, handle, or device of any kind revealed itself.
I widened my search, wandering about the walls, but they seemed sheer, impenetrable. There seemed to be no place in which a lever or handle might be concealed. Then, with a shout of anger at my stupidity, I ran to the shallow cistern in the center of the pit and fell on my stomach before the chill, foul water. I thrust my hand into the slimy water, desperately examining the bottom.
My hand clutched a valve, and I turned it fiercely as far as it would go. At the same time from the escarpment came a smooth, rolling sound as a great weight was effortlessly balanced and lifted by hydraulic means. To my amazement, I saw that an immense opening had appeared in the wall. An enormous slab, perhaps fifty, feet square, had slid upward and backward, revealing a great, dim, squarish tunnel beyond, a tunnel large enough for a flying tarn. I seized the tam reins and drew the beast into the opening. Inside the door I saw another valve, corresponding to the one hidden under the water of the cistern. Turning it, I closed the great gate behind me, thinking it wise to protect the secret of the tunnel as long as possible.
Inside, the tunnel, though dim, was not altogether dark, being lit by domelike, wire-protected energy bulbs, spaced in pairs every hundred yards or so. These bulbs, invented more than a century ago by the Caste of Builders, produce a clear, soft light for years without replacement. I mounted the tarn, who was visibly uneasy in this strange environment. Without much success, by hand and voice, I tried to soothe the beast's apprehensions. Perhaps I spoke as much for my. own benefit as his. The first time I hauled on the one-strap, the bird would not move; the second time he lifted into flight, almost immediately scraping the ceiling of the tunnel with his wings, protesting shrilly. My helmet protected me as my head was roughly dragged against the granite of the ceiling. Then, to my pleasure, instead of alighting, the tam dropped a few feet down from the ceiling and began to streak through the tunnel, the energy bulbs flashing past me to form in my wake a gleaming chain of light.
The end of the tunnel widened into a vast chamber, lit by hundreds of energy bulbs. In this chamber, though empty of human beings, was a monstrous tam cot, in which some twenty gigantic, half-starved taros huddled separately on the tarn perches. As soon as they saw us, they lifted their heads, as if out of their shoulders, and regarded us with fierce attention. The floor of the tam cot was littered with the bones of perhaps two dozen tarns. I reasoned that the taros must be those of the men of Marlenus, left in the tarn cot when he entered the city. He had been cut off. Left without care for weeks, the tares had had nothing to feed upon but one another. They were wild now, crazed by hunger into uncontrollable predators.
Perhaps I could use them.
Somehow I must liberate Marlenus. I knew that when I entered the palace my presence would be inexplicable to the guardsmen and that I would not long be able to pass myself off as a herald of Pa-Kur, certainly not when it became clear that it was my intention to depart with Marlenus. Therefore, impossible though it might seem, I must devise some plan to scatter or overcome his besiegers. As I pondered, the fragments of a plan took form in my mind. Surely I was now beneath the Central Cylinder, and the embattled Marlenus and his men were somewhere above me, sealed off by the guardsmen of Ar. At the top of a broad series of stairs I saw the door that must lead to the Central Cylinder and noted with satisfaction that its dimensions were large enough to permit the passage of a tarn. Fortunately, almost at the foot of the stairs lay one of the gates of the taro cot.
I took my taro-goad and dismounted. I climbed the stairs that led to the portal into the cylinder, turned the valve, and as soon as the portal began to move, raced down to the tarn cot and swung open that barred gate which lay nearest the foot of the stairs. I stood back, partly shielding myself with the gate. In less than a few seconds the first of the scraggy tarns had lit on the floor of the cot and poked his ugly head through the door. His eyes blazed as he saw me. To him, I was food, something to be killed and eaten. He stalked toward me, around the gate. I struck at him with the taro-goad, but the instrument seemed to have no effect. The darting beak lunged at me again and again; the great claws grasped. The taro-goad was tom from my hand.
In that instant a great black shape hurtled into the fray, and the tarn had met his match. Ripping savagely with his steel-shod talons, slashing with his scimitar like beak, my sable war tam in a matter of seconds left the attacking tam a shuddering heap of feathers. With one of the great steel-shod talons on the body of his fallen foe, my tarn emitted the challenge scream of his kind. The other tarns, poking out of the tarn cot, seemed to hesitate and then to notice the open door into the cylinder.
At that moment, to his own misfortune, a passing guardsman of Ar discovered the opened door that had mysteriously appeared in the wall of the first floor of the Central Cylinder. He stood framed for a moment in the doorway and shouted, a shout half of discovery, half of mortal fear. One of the starved tarns, with a leap and stroke of his wings, lunged upward, catching the man in his beak. The man screamed horribly. Another taro reached the portal and tried to pull the body from the beak of its possessor.
There was another shout from within, and several more guardsmen rushed to the opening. Immediately the hunger-wild tarns surged upward, eager for flesh. The tarns, all of them, entered the cylinder, the palace of Marlenus. In the great hall I could hear the fearful noise of unnatural carnage, the screams of the men, the screams of the tarns, the hiss of arrows. the wild blows of wings and talons. I heard someone shout, a weird, terrified cry, 'Taros!' An alarm bar, a hollow metal tube struck by hammers, began to ring in frenzy.
In two or three minutes I led my own tam up the stairs and through the opening. I was sick at the sight that confronted me. Some fifteen tarns were feeding on the remains of a dozen or so guardsmen, detaching and devouring limbs. Several tams were dead; some were flopping about awkwardly on the marble floor, pierced by arrows. There were no living guardsmen in sight. Those who had survived had fled from the room, per haps up the long, wide, circling stairwell that climbed the inside of the cylinder.
Leaving my tarn below, I climbed the stairs, my sword drawn. When I reached that portion of the stairwell adjoining the upper floors, devoted to the private use of the Ubar, I saw some twenty or thirty guardsmen, behind them a barricade of tile and taro wire which they had erected. It was not simply that my sword was drawn. To them, my presence was unauthorized, and my Assassin's garb, far from being a safe-conduct, was an incitement to attack. Some of the guardsmen had undoubtedly fought below with the tarns. They were drenched with sweat; their clothing was torn; their weapons, drawn, were red with blood. They would associate me with the tarn attack. Without waiting to call for my identity or engage in any protocol whatever, they raced toward me.
'Die, Assassin!' one of them screamed, and struck downward with his blade.
I slipped under the blade and ran him through. The others were upon me. Much of what took place then is jumbled in my memory, like the fragments of some bizarre, incomprehensible dream. I remember them pressing downward, so many, and my blade, terrible, moving as if wielded by a god, meeting their steel, cutting its path upward. One man, two, three sprawled down the stairs, and then another and another. I struck and parried and struck again, my sword flashing forth and drinking blood again and again. I seemed to be beside myself and fought as if I might not be what I knew I was, what I thought myself to be — Tarl Cabot, a simple warrior, one man. The thought flamed through me in the violent delirium of battle that in those moments I was many men, an army, that no man could stand against me, that it was not my blade or my heart they faced but something I myself only dimly sensed, something intangible but irresistible, an avalanche, a storm, a force of nature, the destiny of their world, something I could not name but knew in those moments could not be denied or conquered.
Suddenly I stood alone on the stairs, except for the dead. I became dimly aware that I was bleeding from minor cuts in a dozen places.
Slowly I climbed the remainder of the stairs until I came to the barricade which had been erected by the guardsmen. I called out, as loudly as I could, 'Marlenus, Ubar of Ar!'
To my joy, from somewhere above, around the curve of the stairs, I heard the voice of the Ubar. 'Who would speak with me?'
