To fly through the air was a terrifying experience. Kincar had ranged the mountain heights since he had been large enough to keep his seat on a larng pad and follow Wurd hunting, in the years before the old lord of Styr had been reduced to level country riding and at last to his bed. And Wurd's acquaintance with sheer ledges, far drops, clifi edges had been wide. But to stand with ones' boots planted on solid rock and look out upon nothingness was far different, Kincar discovered, than to rise into that nothingness knowing that under one was only a flat platform of no great thickness.

He fought his panic, that picture his imagination kept in the forepart of his mind of the platform dissolving, of his helpless body turning over and over as it fell to the ground below. How had the Star men been able to travel the sky and the depths of s.p.a.ce? Or were they alien to this fear he knew? He wriggled about, but all he could see of the two were their feet. The Star Lords of his own Gorth had had no such fliers. However, they might well accept such traveling as natural.

There was a windbreak on the front of the platform, and he was lying behind the control seats. Yet the chill of- that journey bit deep, and the cloak was but small protection. As the minutes pa.s.sed, Kincar's panic subsided, and it seemed to him that from the Tie spread a gentle heat to banish the worst of the cold. He had been afraid on the field when the ord hatch had turned their attention to him, but that was an honest fear to be fully understood. Now he knew a queer apprehension, the same quiver of nerves and tenseness of muscles that a swordman knows before the command to charge is given at a spear-festing. He tried to school himself with the knowledge that for him there would probably be no return from this flight.

Against Gorthian captivity a man could plan, foresee. But among the Star Lords what chance had he? There was but one thing-Sood's amazing experience with the Tie and this Lord Dillan's wariness of that same token. A slim advantage-perhaps. He had listened to talk in the mountain hold. There were unseen powers-"energies" the Lord Dillan he followed called them. Some of these energies had activated the between-worlds gates through which they had come into this Gorth. And during that pa.s.sage the Tie had also proved to be a conductor of energy, as Kincar could prove by a scar he would carry until he pa.s.sed into the Forest.'

The Tie, in addition, might have its own "energies," which would be inimical to the aliens. That night in the forgotten shrine, the talisman had been recharged with the power native to it. It must carry a full supply. If he only knew more of its potentialities! But he had had no desire to follow the Threefold Way, to train as a Man of Power-for he had understood that he could not have the Way and Styr together and his heart had lain with Styr. So all he had to guide him were the mystical invocations of any believer, the legends and half-whispers. Had he been adept with the Tie, what might he not have accomplished-what could he not do?

The flier swooped, and Kincar fought sickness from the resulting flare of panic. Was it falling, coming apart to crash them to the earth?

But the swift descent slowed. Walls flowed up to cut off the light. They might be dropping down the mouth of a well. The flier came to a stop with less force, than that with which a foot is set upon the floor, and both Star men arose. They had reached their destination.

Lord Rud made no move toward the captive. It seemed that he disliked laying hand upon Kincar. But Lord Dillan pulled the half-Gorthian up, cut the thongs about his ankles and, surprisingly enough, those about his wrists also. His arms fell heavily to his sides, his hands swollen. Lord Dillan picked up the bag containing Vorken and thrust it at him. He caught it clumsily, making a silent resolve not to display any sign of the intense pain any movement of hands or arms cost him.

"You will walk quietly where you are told." Lord Dillan spoke with the exact.i.tude of one giving orders to a slow-witted child. "For if you do not, you shall be burned with this force stick." He had taken from his belt a rod not unlike the one- Kincar had used in suard-hunting. "It will not kill, but the pain will be worse than death by mord, and you shall never be. free of it. Do you understand?"

Kincar nodded. He could believe that the Dark One meant exactly what he said and uttered no vain bluff. Could he hope for a speedy death if he attempted flight? Would he flee if that were the end? As long as a man was alive, he could nourish hope, and Kincar had not yet reached the point where he would try for death as a hunter tries for an easy thrust at his prey. Carrying Vorken, he obediently followed Lord Rud out of the chamber where the flier rested, down a sideway, while behind tramped Lord Dillan, weapon in hand.

The living quarters of the fortress at U-Sippar had been of alien workmanship and materials. The narrow pa.s.sage in which they now walked was as unlike that as that had been from the Gorthian architecture upon which it had been based. Here were no flitting rainbow colors, only an even sheen of gray, which, as he brushed against it, gave to Kincar the feel of metal. And the pa.s.sage ended after a few feet in a stair ascending in a spiral, the steps no wider than a ladder's treads. Kincar grasped the guard rail, Vorken in the crook of his left arm. He kept his eyes resolutely on the legs of Lord Rud going up and up, refusing to yield to any temptation to look down into the dizzy well beneath them.

They pa.s.sed through a series of levels from which ran other pa.s.sages, emerging from the floor of such a level to climb again through its roof. Kincar could not even speculate upon the nature of the building in which so unusual a staircase formed the core. On the third such level Lord Rud stood away from the stair, turning into a side corridor, and Kincar went after him. So far they might have been in a deserted building. Though the noise of their climbing feet echoed hollowly up and; down that well, there had been no other sound to break the quiet, no sign of any guardsman or servant on duty. And there was a queer, indefinable odor- not the dank emanation of the hold walls, of U-Sippar's fortress, but in its way as redolent of a remote past, of something long closed against the freshness of wind and cleansing sunlight.

The pa.s.sage into which Rud had turned was hardly more than a good stride long. He set his palm flat upon a closed door, and under that touch it rolled back into the wall so that they might enter an odd chamber. It was a half circle, a curved wall ending in a straight one-the shape of a strung bow, the door being in the straight wall. s.p.a.ced at intervals along the curved surface were round windows covered with a clear substance strange to Kincar.

A padded bench ran along the wall under the level of the windows, and there was an equally padded covering on the floor and over the walls. Otherwise the room was bare of either inhabitants or furnishings. Lord Rud glanced around and then stepped aside to allow Kincar to enter. When the Gorthian had pa.s.sed through the door, he went out and the portal closed, leaving Kincar alone.

He pulled loose the covering about Vorken and evaded the exasperated snap of her bill, loosing her on the bench where she waddled along with her queer rolling gait, her claws puncturing its padding and having to be pulled out laboriously at every step. Kincar knelt on the same surface to look from one of the windows.

No U-Sippar lay without. The structure he could survey was totally unlike anything he had seen on either Gorth. Beyond were several towers, not the square stone ones he had known all his life. Fashioned of metal, they caught the sun and reflected its beams in a blaze of fire. All were exactly alike, round with pointed tips that stood tall in the sky. Kin-car surmised that a similar building harbored him. Linking -all of them together-by pressing tight to the transparent pane he could just make them out-were a series of walls-walls thick enough to contain corridors or rooms. But those were of the native stone. Metal towers-pointed- Kincar's swollen hands closed upon the edge of the window until he felt the pain of that grip. Not towers-no, not towers. Ships! The sky ships of the Star men-here forever earthbound, built into a weird fortress. He had heard them described too many times by men who had visited Terranna on his own Gorth not to recognize them. Was this the Terranna of this Gorth? It could be nothing less than the heart of the Dark Ones' holdings.

On his own Gorth those ships had gone forth again-out to the stars. Here that must be impossible. They had been anch.o.r.ed to the earth. They had rooted their ships, determined to possess Gorth for all time.

As he studied that strange mating of ship and stone, Kin-car could spot no signs of life. Nothing moved along those walls, showed at any of the round ports that now served as windows. And there was a sense of long absence of tenantry about it all. A storehouse-Kincar could not have told why that particular thought took possession of him nor why the conviction grew that he was right. This must be a storehouse for the aliens. As that it would be well guarded, if not by warriors, then by the magic the Star men controlled. A race who flew through the air without wonder would have weapons mightier than any sword swung by a Hand to protect their secret place.

The age-old thirst that arises in any man at the thought of treasure tempted Kincar. This whole city, fortress, whatever it was, must be thinly populated. If he could get free of his present lodging and explore-I But the door was sealed tightly. Vorken hissed from the bench. She was uneasy in this closed room as she had never been in the hold. Kincar went from one window to another. Three,merely showed him other aspects of the tower-ship building, but the other two gave him a view of the countryside.

There were no trees, but odd twisted rocks. Some, with a puff crown of snow, were vaguely familiar. He had certainly seen their like before. Then the vivid memory of their ride through the wasteland desert to the first gate returned. There were no signs of vegetation here, unless its withered remnants lay under the snow. But in the distance was the bluish line of hills, the mark of mountains. And seeing those, Kincar's hopes rose illogically.

Vorken's head b.u.mped against him. She raised a forefoot to sc.r.a.pe his arm and draw his attention. Though none of his race had ever believed the mords lacked intelligence, it was generally conceded that their mental mazes were so alien to that of mankind that communication between the two species was strictly limited to the recognition of a few simple suggestions, mostly dealing with food and hunting. But it was plain that now Vorken was trying to convey something in her own way. And he did what otherwise he would have hesitated to try, since mords were notoriously averse to handling. He sat down on the bench and lifted her to his knees.

She complained with a hiss or two. Then she squatted, her red eyes fastened upon his as if she would force upon him some message. She flapped her wings and mouthed the shrill whistle she gave when sighting game.

Kincar's preoccupation with Vorken was broken by the sudden heat on his breast. The Tie was glowing. Somewhere within the ship-tower an energy was being loosed to which that highly sensitive talisman responded. He hesitated. Should he take it off lest he risk a bad burn and incapacitate himself-or should he continue to wear it?

To his overwhelming surprise, Vorken stretched her skinny neck and b.u.t.ted her head against him, directly over the Tie, before he could fend her away. She pressed tightly to it, lifting her claws in warning when he would have moved her, giving voice to the guttural battle croaks of her kind.

The warmth of the Tie increased as the mord pressed it tightly against him. But that did not appear to disconcert Vorken. Her battle cries stopped. Now she chuckled, the little sound she made when she was very content with her world. And Kincar himself felt relaxed, confident, fast losing his awe of both surroundings and captors.

XV.

TRIAL OF STRENGTHS.

THAT SENSE OF well-being persisted. Vorken's beak gaped in a yawn. Her eyes closed as she huddled close, her grotesque head still resting against him. But Kincar felt far from sleepy. Instead he was alert mentally and physically, as he had never been before that he could remember. The feeling that there was no task beyond his accomplishing grew. Was this how the full blood of the Star breed lived? It must be! This supreme confidence in one's self, the certainty that no difficulty was too great- Kincar laughed softly. And something in that sound struck below the surface of his present well-being, brought a tinge of doubt. Perhaps because of the Tie he was doubly alert to any hint of danger. Did that emotion, the self-confidence, stem from the energy in the talisman, or was it more magic of an alien sort? It would be very easy to work upon a man's mind-if you had the Star resources-to give him an elevated belief in his own powers until he was rendered careless. So very easy.

There was one way of testing that. Kincar lifted the Tie by its chain, slipped the chain over his head, and put down the stone at a short distance from him on the bench. The warmth on his flesh was gone. Vorken stirred. Her head arose as she regarded Kincar with an open question. But he was too preoccupied to watch the mord.

Pressing in upon him, with the force of a blow from a giant's fist, was an overwhelming and devastating panic, a fear so abject and complete that he dared not move, could only get air into his cramped and aching lungs in short gasps. His hands were wet and slippery, his mouth dry, a sickness ate him up inwardly. In all his life he had never known such terror. It was crushing all ident.i.ty from him, turning him from Kincar into a mindless, whimpering thing! And the worst of it was that he could not put name to the reason for that fear. It was inside him, not from without, and it was filling all of his burnt-out body sh.e.l.l-Vorken squalled, a scream that tore at his ears. Then the mord struck, raking him with her claws. The pain of her attack broke the spell momentarily. He made a supreme effort, and by its chain drew the Tie back into his hands. In those sweating palms he cupped it tight as Vorken ripped at him. But once he had it, the panic was gone, and when the chain was again over his head, the Tie resting in its old place, he sat weak and shaken, but whole and sane once more-so whole and sane he could not quite believe in what had struck him as viciously as the mord.

Blood trickled from the scratches Vorken had given him. Luckily she had not torn deeply. Now she crouched once more on his knees, turning her head from side to side, giving voice to a whimpering complaint as one of her punishing forefeet raised to the Tie. It was that talisman that had saved them both from utter madness-the why and wherefore of that deliverance being more than Kincar could understand. He could only accept rescue with grat.i.tude.

Kincar had left Styr with no more training than any youth who could confidently aspire to the lordship of a holding, and a small, mountain holding at that. He had ridden away under the shock of the abrupt revelation of his half-blood, unable to quite accept that heritage. Word's secret gift of the Tie, with all that meant, had been an additional push along a new path of life. His painful experience at the gates, and his acceptance thereafter by Lord Dillan and the Lady Asgar as one who had rightful guardianship of a power they respected, had tempered him yet more. Perhaps his volunteering for the expedition into the lowlands had been born of a spirit of adventure, rooted in the quality that sent any young warrior to a spear-festing. But with it had gone the knowledge that he alone of the hold was fitted for that Journey.

What had happened that night in the forest shrine he did not understand.- He was no adept to be able to recall the work of the Three. But now he believed that he had ridden away from there subtly altered from the Kincar who had taken shelter. This last ordeal might be another milepost on his road. He would not be as the Star Lords, nor as the ruler of Styr that he might have been had Jord not taken from him that future-but a person he was not yet able to recognize.

Kincar was sure he was no mystic, no seeker of visions, or wielder of strange powers. What he was-now-he did not know. Nor did he have the time to become acquainted. It was better to accept the ancient beliefs of his people-his mother's people-and think that he was a tool, mayhap a weapon, for the use of the Three, that all he did was in Their service.

There was a security in that belief. And just now more than anything else he desired security, to trust in something outside his own shaken mind and body.

He had been right in his surmise that he would be allowed scant time for self-examination. The door of the chamber rolled back into the wall. Vorken hissed, flapped her wings, and would have taken to the air in attack had not Kincar, fearing for her Life, made a hasty grab for her feet.

Lord Dillan stood there. He did not speak at once, but, though he did 'not display surprise by any sign readable to Kincar, the latter thought his alertness astonished the other.

"Slave-" The harsh grate of the Star Lord's voice was meant to sting, as the whips of the Hands had stung their miserable captives.

Kincar stared as steadily back. Did the Dark One expect from him a cringing plea for nonexistent mercy?

Now the wand of power was in Dillan's hands as he spoke again.

"We have underestimated you it seems, fellow!"

"It appears that you did, Lord." The words came to Kincar as if someone else who stood apart and watched this scene selected them for his saying.

"Rud's offspring in truth!" Lord Dillan laughed. "Only our own kin could stand up against a conditioner set at that level Let him try to deny this to the council. Come-you!"

He gestured and Kincar went. Vorken had struggled free of his grip and now balanced on his shoulder, a process made painful by her claws. Yet he was glad to have her with him, a steadying reminder of that other Gorth where a man could not be so beset by magic.

"Up!" The single word set him climbing once more, up the ladder spiral of the stairway. On the next level they came upon something he had not sighted from the windows. Connecting one ship with another, strung far above the ground, was an aerial bridge-temporary, Kincar judged, for so lightweight a creation could not survive the first real windstorm.

But frail as it was, it was also now their road. Kincar clung with his full strength to the hand rope, some of the fear he had known on the flying platform sweeping back. To stop at all, he guessed, would be fatal. So he made the crossing, step by step, his attention all for the port door ahead.

He was within a foot or two of that door when he remembered Vorken. He had no way of escape-that he could see now-from the towers, not with the armed Lord Dillan ready to blast him. But perhaps Vorken could be saved. Still holding to the guide rope with his left hand, he half turned, flicking out with his cloak, at the same time giving the hunter's call for a sky search.

Was it by luck alone that the edge of the cloak entangled with the Star weapon? He had been well trained in the swordsman's art of using the enveloping fabric to bewilder and disarm an opponent, but he had never attempted such a throw under these adverse circ.u.mstances. Skill or luck, he engaged the rod until Vorken was up and away, rising can-nily not in her usual spirals but headed in an arrow's flight for the distant hills.

Oddly enough, Lord Dillan made no effort at retaliation. He loosened the cloak, and it went flapping down into the chasm below them, where Kincar dared not look. He had not been lucky or skillful enough to have dragged the weapon from the other, and now it was centered upon him.

"Go on," Lord Dillan ordered, and Kincar, sure of Vorken's escape and treasuring that small triumph,, went ahead, pa.s.sing through the port into the second of the Star ship towers.

Two more of the Star Lords awaited him there-but neither were doubles of those he had known in the hold. To be faced by a Lord Frans, a Lord Bardon, a Lord Jon who were not what they appeared would have added to his burden at that moment. These men were all younger than Lord Dillan, if he could judge the age of the Star breed rightly, and both looked soft, lacking that alertness of mind and body his captor possessed-traces of which Lord Rud had displayed. They had that inborn arrogance that comes not from the authority of a man who has rightfully held leadership over his fellows through innate traits of character, but that which is based instead upon never having one's will disputed, and having absolute power over other intelligent beings by birthright alone.

Neither concealed his amazement at Kincar, one asking Lord Dillan a question in their tongue. He snapped an impatient answer and motioned them on.

"Follow!" he told Kincar tersely.

They were about to descend another of the spiral stairways. Descend it! A glimmer of a plan was born-a fantastic plan-perhaps so fantastic that it would work! Success would depend upon how quickly Kincar could move, whether he would be able to take his guards by surprise. He did not think too highly of the newcomers, but Lord Dillan was another matter. However, the cloak trick had worked against him. Kincar could only try, desperate as the plan was. And, making his first move, he clutched at the hand rail of the stair. What he intended might well burn the flesh from his hands. He must have some protection for them- He was bare to the waist; there was no way to tear any strips from his hide breeches. If he only had the cloak again!

One young Star Lord was already pa.s.sing through the first of the well openings. He was the only barrier between Kin-car and the realization of his plan. And he was wearing not the tight weather suit of Lord Dillan but a loose shirt of some light material.

Kincar started down the ladder with a meekness he trusted would be disarming. The steps were so narrow, the incline so steep that he hoped Lord Dillan would have to give a measure of his attention to his own going and so might be a second or so late in attacking when the prisoner moved.

The young lord was disappearing into the well at the next level now and Lord Dillan was waist-deep in the first, Kincar on the stair between them. The Gorthian threw himself forward, his weight on his hands. To the watcher it might seem he had missed a step. His foot swung out and caught the young lord on the side of the head. The other gave a choked cry and caught at the floor. It was that instinctive move to save himself that aided Kincar. He landed beside the alien and tore at his shirt, the thin stuff coming away in his hand. He pushed through the well opening, pulling over the half-conscious man to block it after him, and slid down the spiral, with only his hands on the rail as support.

He whirled about, wondering if he could brake his descent now. There were shouts behind, perhaps calls for help, and the clatter of boots. Friction charred the cloth under his hands, pain bit at his palms, but he held on. Two more levels, three; there was a regular din behind him now. Beneath him, two levels ahead, was solid floor, and he made ready as best he could to meet it. With dim memories of how he had taken falls in his first days of riding, he willed his muscles to go limp, tried to ball together, and prayed against the horror of broken bones.

There was blackness, but even in the semiconscious state he still strove for escape. When he was again truly aware of his surroundings, he crawled on smarting hands and aching knees down a narrow corridor.

Praise be to the Three, he had come through that landing unbroken, though his body ached with bruises. Wincing at sharp stabs, Kincar got to his feet and lurched on, only wanting now to put as much distance between himself and the noise as he could.

The walls about him changed as he stumbled over a high step. They were stone, hot metal, now. He must be within one of the walls that tied together the ship-towers-far nearer ground level. Surely here he could find a door to the outer world.

Though he did not know it until afterwards, Kincar was perhaps the first prisoner within that maze who was in command of his mind and body, unbroken by the conditioner. To the men who hunted him, he was an unknown quant.i.ty they were not prepared to handle. They did not give him credit for either the initiative or the speed and energy he was able to muster.

The stone-walled corridor wove on with no breaks of either windows or doors. He sped along it at the best pace he could keep, nursing his scorched hands against the Tie, for it seemed to him that there was some healing virtue in the talisman. At least it drew away the worst of the pain.

To his dismay Kincar came to a second of the ridge steps, marking the entrance to another ship-tower. But there was no turning back, and, with all the chambers that must exist in the ships, he could either find a hiding place or access through a port window to the top of a connecting wall. The dim light that radiated from both walls of stone and of metal showed him another spiral stairway. He made a complete circuit below. Two doors, both fast closed, and neither would open. He dared not linger there. Necessity sent him climbing.

The first level gave upon more doors all closed, all resisting his efforts to force them. Another level, the same story. He leaned, gasping, against the hand rail, fearing that he had been driven into a trap with the Dark Ones able to pick him up at their leisure.

The third level, and as his head arose through the well, he could have shouted aloud his cry of triumph-for here, a door gape'd. In his eagenerness he stumbled and went to one knee. And in that moment he heard the unmistakable pound of feet below.

He fell rather than sprang through the door. Then'he set his hand flat against it as he had seen Lord Dillan do. It moved! It fell into place behind him! He could see no way of locking it, but the very fact that there was now a closed door between him and the stairwell gave a ghost of safety.

The corridor before him was a short one, and he burst into a small, round room. The walls rose up to the open sky- He had seen it-or its like before-for here was berthed a flier like the one that had brought him here.

He was trapped. There was no climbing the smooth walls of the well that held the flier. Soon-any moment now-the Dark Ones would be through that door he could not lock, would take him as easily as one roped a larng in the spring trapping pens. Why they had not already been upon him he did not know. As he hesitated there, he heard, more as" a vibration through the walls than a sound, the pounding feet. But there was no fumbling at the door. Kincar guessed that his pursuers had gone to the next level, that the closing of the door had momentarily hidden his trail. Should he-could he dodge out now and backtrack while the hunters were on the higher levels? He could not bring himself to that move. The wild slide down the well ladder in the other tower and his run through the pa.s.sages had worn him down; his energy was fading fast.

What did he do now? Remain where he was until they searched from chamber to chamber and found him? He swayed to the flier, dropped on one of the seats within it, his hurt hands resting palms up on his knees. If he had only the proper knowledge, he could be free-away without any difficulty at all. The b.u.t.tons on the panel before him were frustrating-if he only knew which ones- The vibration of the hurrying hunters reached him faintly. They were coming back down again-or could that be reinforcements arriving from below? Dully Kincar studied the controls. Nothing in his dealing with the Star men he knew had given him a hint of their machines. But he could not be taken again-he could not! Better to smash the flier and himself than to sit here tamely until they broke in.

Kincar closed his eyes, offered a wordless pet.i.tion to those he served, and made a blind choice of b.u.t.ton. Only it was the wrong one. Heat walled up about him as if a cloak had been flung about his shivering body. Heat answered that b.u.t.ton. He counted one over, relieved that disaster had had not resulted from his first choice.

A shaft of light struck upon the rounded wall before him, flashing back into his dazzled eyes. It startled him so that he triggered the third b.u.t.ton before he thought.

He grabbed the sides of his seat in spite of the pain in his hands. His gasp was close to a scream, for the flier was shooting up, out of that well, at a speed that almost tore the air from his lungs. The machine broke out of the well, went on and on up into the sky. It must be stopped-or he would reach star s.p.a.ce. But how to control it he had no idea.

With the faint hope that the function of the b.u.t.ton next to the last one he had pushed might counteract it, he thrust with an urgent finger. He was right, inasmuch as that sickening rise stopped. But his flight was not halted. The flier now skimmed forward with an equally terrifying speed, as might an arrow shot from a giant bow. But for the moment Kincar was content. He was not bound for outer s.p.a.ce, and he was headed with breath-taking speed away from the towers. He crouched on the seat, almost unable to believe his good fortune.

When he grew more accustomed to flight, he ventured to look below, keeping a good grip on the seat and fighting vertigo. The same chance that had brought his finger to the right b.u.t.ton had also dictated the course of the flier. It was headed across the waste plain, not for the sea lowlands and the cities ruled by the Dark Ones, but toward the distant mountain range-only not so distant now-where Kincar might have a faint hope of not only surviving but eventually rejoining those at the hold.

There remained the problem of grounding the flier. Just at the moment he had no desire to experiment-until at least one mountain lay between him and pursuit. And, thinking of pursuit sent him squirming about to look behind. The Dark Ones must have more than just one such flier-would they take to the air after him? But above the rapidly diminishing dot of the fortress he could see nothing in the air.

What might have been two-three days' travel for a larng flashed below in a short s.p.a.ce of time. Then he was above the peaks he had seen from the ship-towers, skimming-just barely skimming-over snow-crowned rock. If he only knew how to control the flier! Its speed was certainly excessive. His elation gave way once more to anxiety as he imagined what might happen should the machine crash head-on against some peak higher than its present level of flight.

XVI.

RESCUE.

IF NO OTHER flier arose from the ship-towers to intercept Kincar's runaway transport, something else did. He first knew of his danger when a piercing shriek of rage and avid hunger carried through the rush of air dinning at his eardrums. Compared to that challenge, Vorken's most ambitious call was a muted whisper. Kincar stared aloft and then shrank in the seat, for what swooped at him now was death, a familiar death, well known to any Gorthian who had ever roamed the mountain ranges.

Vorken was a mord, but she was counted a pygmy of her species. Among the frigid heights lived the giants of her race, able to carry off a larng at their pleasure. And their appet.i.tes were as huge as their bodies. They could be entrapped with a triple- or quadruple-strand net and men well versed in the tricky business to handle it, but such a netting meant days of patient waiting, luring the creature to the ground with bait. Once on the surface of the mountainside or plateau, they were enough at a disadvantage to be snared, though it was always a risky business, and no one was surprised if such a hunting party returned minus one or more of the hunters.

No one had ever faced a sa-mord in the air. No one had lived through an attack made when the attacker was wing borne and free. And Kincar had no hope of surviving this one.

With the usual egotism of a man, he had reckoned that he was the aim of those claws, whereas, to the sa-mord he was merely an incidental part of the thing it attacked. It made its swoop from the skies, talons stretched to grasp the flier, only to discover it had not properly judged the speed of this impudent air creature, missing its strike by a foot or more.

It plunged past in an instant, screaming its furious rage, and was gone before Kincar could realize that he had not been pierced through by those claws. Had he then been able to control the flier, he might have won free or tired the creature out to the point where it would have given up the chase. But such evasive action was beyond his power. He could only stay where he was, half sheltered by the back of the seat and the windbreak, as the flier bore straight ahead, while behind, the sa-mord beat up into the sky for a second strike.

Like their smaller relatives, the sa-mords had intelligence of a sort, and most of that reasoning power was centered upon keeping its possessor not only fed but alive. The sa-mords were solitary creatures, each female having a section of hunting territory where she ruled supreme, ready to beat off any of her kind who threatened her hold on sky and earth therein. And to such battles each brought acc.u.mulated knowledge of feint, attack, and the proper use of her own strength.

So when the sa-mord now struck for the second time, from a yet higher point, she had recalculated the speed of the flier and came down in a dive that should have brought her a little ahead and facing the enemy with waiting claws, a favorite fighting position.

Only again mechanical speed proved her undoing, for she hit directly on the flier's nose. The windbreak was driven into her softer underparts by the force of that meeting. Claws raked across the shield, catching on the seats, as she squalled at her hurt. Kincar, wedged in as flat as he could get, felt rather than saw that gaping beak that snapped just an inch or two above him as blood spurted from torn arteries to flow greasily.

The machine faltered, dipped, fought against that struggling weight impaled on its nose. It was losing alt.i.tude as the sa-mord beat and tore at it. Only the fact that the flier was metal, and so impervious to her attack, saved Kincar during those few moments before they were carried into a thicket of snow-line scrub trees. There the sa-mord's body acted as a shock absorber and cushion as they slammed to a final stop.

Kincar, the breath beaten out of him by the sharp impact, lay where he was, the stench of the torn creature thick in the air. Gone was the heat that had enfolded him. Shivering in the lash of mountain wind, he at last fought his way out of the grisly wreckage and staggered along the splintered swath the flier had cut. One sa-mord to a hunting territory was the custom. But there were lesser things that could scent blood and raw meat from afar. Weaponless he could not face up to such carrion eaters. So, guided more by instinct than plan, he reeled downslope.

Luckily the flier had not crashed on one of the higher crests, and the incline was not so straight that he could not pick a path. Here the scrub wood was thin. It was possible to set landmarks ahead to keep that path from circling.

It must be far past midday, and he would have to find shelter. From upslope there came a m.u.f.fled yapping, then a growling, rising to roaring defiance. The scavengers had found their feast, and there was no hope of returning to the wreckage. In fact, that din spurred Kincar to a faster pace, until he lost his footing and fell forward, to roll into a snowdrift.

Gasping, spitting snow, he struggled up, knowing that to lie there was to court death. Only by keeping on his feet and moving did he have the thinnest chance. Fortunately the sky was clear of clouds; no storm threatened.

That fall and slide had brought him into a valley with a trickle of stream at its bottom. The water was dark, flowing quickly, with no skim of ice. He wavered down to it and went on his knees. Now he could feel the faint, very faint warmth exuding from the riverlet. This must be one of the hot streams, such as he had discovered in the hold valley. He had only to trace it back to its source and that heat would grow, promising him some protection against the cold of the coming night.

It was an effort to get to his feet again, to flog his bruised body along. But somehow he kept moving, aware through the fog of exhaustion that there were now trails of steam above the water, that the temperature in the valley was rising. Choking and coughing from the fumes, he fell against a boulder and clung there. He had to have the heat, but could he stand the lung-searing exhalations of the water?

Slowly he went down beside the rock, certain he could go no farther, and no longer wanting to try. It all a.s.sumed the guise of a dream, and the inertia of one caught in a nightmare weighted him. There was the grit of stone against his cheek and then nothing at all.

The sa-mord loomed above him. He had been very wrong. It was not killed by the flier, and now it had tracked him down. In a moment he would be rent by claw and beak. Only it was carrying him up-higher than the mountains! They were swinging out over the waste to the ship-towers. A flier bore him-no sa-mord but a flier! The machine was rising at the nose-it would turn over, spill him down- "Get him up if you have to lash him! We can take no chances on this climb-"
