'Tiberias gave one scream, and then his throat was torn open and he was selling his otter skins in h.e.l.l. The mule ran away into the woods. Listen! Even now you can hear him thrashing about under the trees. The demon didn't have time to take Tiberias' head; it took fright as we came up.'

'As you came up,' amended Balthus. 'It must not be a very terrible creature if it flees from one armed man. But how do you know it was not a Pict with some kind of a hook that rips instead of slicing? Did you see it?'

'Tiberias was an armed man,' grunted Conan. 'If Zogar Sag can bring demons to aid him, he can tell them which men to kill and which to let alone. No, I didn't see it. I only saw the bushes shake as it left the trail. But if you want further proof, look here!'

The slayer had stepped into the pool of blood in which the dead man sprawled. Under the bushes at the edge of the path there was a footprint, made in blood on the hard loam.

'Did a man make that?' demanded Conan.

Balthus felt his scalp p.r.i.c.kle. Neither man nor any beast that he had ever seen could have left that strange, monstrous three-toed print, that was curiously combined of the bird and the reptile, yet a true type of neither. He spread his fingers above the print, careful not to touch it, and grunted explosively. He could not span the mark.

'What is it?' he whispered. 'I never saw a beast that left a spoor like that.'

'Nor any other sane man,' answered Conan grimly. 'It's a swamp demon - they're thick as bats in the swamps beyond Black River. You can hear them howling like d.a.m.ned souls when the wind blows strong from the south on hot nights.'

'What shall we do?' asked the Aquilonian, peering uneasily into the deep blue shadows. The frozen fear on the dead countenance haunted him. He wondered what hideous head the wretch had seen thrust grinning from among the leaves to chill his blood with terror.

'No use to try to follow a demon,' grunted Conan, drawing a short woodsman's ax from his girdle. 'I tried tracking him after he killed Soractus. I lost his trail within a dozen steps. He might have grown himself wings and flown away, or sunk down through the earth to h.e.l.l. I don't know. I'm not going after the mule, either. It'll either wander back to the fort, or to some settler's cabin.'

As he spoke Conan was busy at the edge of the trail with his ax. With a few strokes he cut a pair of saplings nine or ten feet long, and denuded them of their branches. Then he cut a length from a serpent-like vine that crawled among the bushes near by, and making one end fast to one of the poles, a couple of feet from the end, whipped the vine over the other sapling and interlaced it back and forth. In a few moments he had a crude but strong litter.

'The demon isn't going to get Tiberias' head if I can help it,' he growled. 'We'll carry the body into the fort. It isn't more than three miles. I never liked the fat fool, but we can't have Pictish devils making so cursed free with white men's heads.'

The Picts were a white race, though swarthy, but the border men never spoke of them as such.

Balthus took the rear end of the litter, onto which Conan unceremoniously dumped the unfortunate merchant, and they moved on down the trail as swiftly as possible. Conan made no more noise laden with their grim burden than he had made when unenc.u.mbered. He had made a loop with the merchant's belt at the end of the poles, and was carrying his share of the load with one hand, while the other gripped his naked broadsword, and his restless gaze roved the sinister walls about them. The shadows were thickening. A darkening blue mist blurred the outlines of the foliage. The forest deepened in the twilight, became a blue haunt of mystery sheltering unguessed things.

They had covered more than a mile, and the muscles in Balthus' st.u.r.dy arms were beginning to ache a little, when a cry rang shuddering from the woods whose blue shadows were deepening into purple.

Conan started convulsively, and Balthus almost let go the poles.

'A woman!' cried the younger man. 'Great Mitra, a woman cried out then!'

'A settler's wife straying in the woods,' snarled Conan, setting down his end of the litter. 'Looking for a cow, probably, and -stay here!'

He dived like a hunting wolf into the leafy wall. Balthus' hair bristled.

'Stay here alone with this corpse and a devil hiding in the woods?' he yelped. 'I'm coming with you!'

And suiting action to words, he plunged after the Cimmerian. Conan glanced back at him, but made no objection, though he did not moderate his pace to accommodate the shorter legs of his companion. Balthus wasted his wind in swearing as the Cimmerian drew away from him again, like a phantom between the trees, and then Conan burst into a dim glade and halted crouching, lips snarling, sword lifted.

'What are we stopping for?' panted Balthus, dashing the sweat out of his eyes and gripping his short sword.

'That scream came from this glade, or near by,' answered Conan. 'I don't mistake the location of sounds, even in the woods. But where--'

Abruptly the sound rang out again - behind them; in the direction of the trail they had just quitted. It rose piercingly and pitifully, the cry of a woman in frantic terror - and then, shockingly, it changed to a yell of mocking laughter that might have burst from the lips of a fiend of lower h.e.l.l.

'What in Mitra's name--' Balthus' face was a pale blur in the gloom.

With a scorching oath Conan wheeled and dashed back the way he had come, and the Aquilonian stumbled bewilderedly after him. He blundered into the Cimmerian as the latter stopped dead, and rebounded from his brawny shoulders as though from an iron statue. Gasping from the impact, he heard Conan's breath hiss through his teeth. The Cimmerian seemed frozen in his tracks.

Looking over his shoulder, Balthus felt his hair stand up stiffly. Something was moving through the deep bushes that fringed the trail - something that neither walked nor flew, but seemed to glide like a serpent. But it was not a serpent. Its outlines were indistinct, but it was taller than a man, and not very bulky. It gave off a glimmer of weird light, like a faint blue flame. Indeed, the eery fire was the only tangible thing about it. It might have been an embodied flame moving with reason and purpose through the blackening woods.

Conan snarled a savage curse and hurled his ax with ferocious will. But the thing glided on without altering its course. Indeed it was only a few instants' fleeting glimpse they had of it - a tall, shadowy thing of misty flame floating through the thickets. Then it was gone, and the forest crouched in breathless stillness.

With a snarl Conan plunged through the intervening foliage and into the trail. His profanity, as Balthus floundered after him, was lurid and impa.s.sioned. The Cimmerian was standing over the litter on which lay the body of Tiberias. And that body no longer possessed a head.

'Tricked us with its d.a.m.nable caterwauling!' raved Conan, swinging his great sword about his head in his wrath. 'I might have known! I might have guessed a trick! Now there'll be five heads to decorate Zogar's altar.'

'But what thing is it that can cry like a woman and laugh like a devil, and shines like witch-fire as it glides through the trees?' gasped Balthus, mopping the sweat from his pale face.

'A swamp devil,' responded Conan morosely. 'Grab those poles. We'll take in the body, anyway. At least our load's a bit lighter.'

With which grim philosophy he gripped the leathery loop and stalked down the trail.

2 The Wizard of Gwawela

Fort Tuscelan stood on the eastern bank of Black River, the tides of which washed the foot of the stockade. The latter was of logs, as were all the buildings within, including the donjon (to dignify it by that appellation), in which were the governor's quarters, overlooking the stockade and the sullen river. Beyond that river lay a huge forest, which approached jungle-like density along the spongy sh.o.r.es. Men paced the runways along the log parapet day and night, watching that dense green wall. Seldom a menacing figure appeared, but the sentries knew that they too were watched, fiercely, hungrily, with the mercilessness of ancient hate. The forest beyond the river might seem desolate and vacant of life to the ignorant eye, but life teemed there, not alone of bird and beast and reptile, but also of men, the fiercest of all the hunting beasts.

There, at the fort, civilization ended. Fort Tuscelan was the last outpost of a civilized world; it represented the westernmost thrust of the dominant Hyborian races. Beyond the river the primitive still reigned in shadowy forests, brush-thatched huts where hung the grinning skulls of men, and mud-walled enclosures where fires flickered and drums rumbled, and spears were whetted in the hands of dark, silent men with tangled black hair and the eyes of serpents. Those eyes often glared through the bushes at the fort across the river. Once dark-skinned men had built their huts where that fort stood; yes, and their huts had risen where now stood the fields and log cabins of fair-haired settlers, back beyond Velitrium, that raw, turbulent frontier town on the banks of Thunder River, to the sh.o.r.es of that other river that bounds the Bossonian marches. Traders had come, and priests of Mitra who walked with bare feet and empty hands, and died horribly, most of them; but soldiers had followed, and men with axes in their hands and women and children in ox-drawn wains. Back to Thunder River, and still back, beyond Black River the aborigines had been pushed, with slaughter and ma.s.sacre. But the dark-skinned people did not forget that once Conajohara had been theirs.

The guard inside the eastern gate bawled a challenge. Through a barred aperture torchlight flickered, glinting on a steel head-piece and suspicious eyes beneath it.

'Open the gate,' snorted Conan. 'You see it's I, don't you?' Military discipline put his teeth on edge. The gate swung inward and Conan and his companion pa.s.sed through. Balthus noted that the gate was flanked by a tower on each side, the summits of which rose above the stockade. He saw loopholes for arrows.

The guardsmen grunted as they saw the burden borne between the men. Their pikes jangled against each other as they thrust shut the gate, chin on shoulder, and Conan asked testily: 'Have you never seen a headless body before?' The face of the soldiers were pallid in the torchlight. That's Tiberias,' blurted one. 'I recognize that fur-trimmed tunic. Valerius here owes me five lunas. I told him Tiberias had heard the loon call when he rode through the gate on his mule, with his gla.s.sy stare. I wagered he'd come back without his head.'

Conan grunted enigmatically, motioned Balthus to ease the litter to the ground, and then strode off toward the governor's quarters, with the Aquilonian at his heels. The tousle-headed youth stared about him eagerly and curiously, noting the rows of barracks along the walls, the stables, the tiny merchants' stalls, the towering blockhouse, and the other buildings, with the open square in the middle where the soldiers drilled, and where, now, fires danced and men off duty lounged. These were now hurrying to join the morbid crowd gathered about the litter at the gate. The rangy figures of Aquilonian pikemen and forest runners mingled with the shorter, stockier forms of Bossonian archers.

He was not greatly surprised that the governor received them himself. Autocratic society with its rigid caste laws lay east of the marches. Valannus was still a young man, well knit, with a finely chiseled countenance already carved into sober cast by toil and responsibility.

'You left the fort before daybreak, I was told,' he said to Conan. 'I had begun to fear that the Picts had caught you at last.'

'When they smoke my head the whole river will know it,' grunted Conan. 'They'll hear Pictish women wailing their dead as far as Velitrium - I was on a lone scout. I couldn't sleep. I kept hearing drums talking across the river.'

'They talk each night,' reminded the governor, his fine eyes shadowed, as he stared closely at Conan. He had learned the unwisdom of discounting wild men's instincts.

'There was a difference last night,' growled Conan. 'There has been ever since Zogar Sag got back across the river.'

'We should either have given him presents and sent him home, or else hanged him,' sighed the governor. 'You advised that, but-- 'But it's hard for you Hyborians to learn the ways of the outlands,' said Conan. 'Well, it can't be helped now, but there'll be no peace on the border so long as Zogar lives and remembers the cell he sweated in. I was following a warrior who slipped over to put a few white notches on his bow. After I split his head I fell in with this lad whose name is Balthus and who's come from the Tauran to help hold the frontier.'

Valannus approvingly eyed the young man's frank countenance and strongly-knit frame.

'I am glad to welcome you, young sir. I wish more of your people would come. We need men used to forest life. Many of our soldiers and some of our settlers are from the eastern provinces and know nothing of woodcraft, or even of agricultural life.'

'Not many of that breed this side of Velitrium,' grunted Conan. 'That town's full of them, though. But listen, Valannus, we found Tiberias dead on the trail.' And in a few words he related the grisly affair.

Valannus paled. 'I did not know he had left the fort. He must have been mad!'

'He was,' answered Conan. 'Like the other four; each one, when his time came, went mad and rushed into the woods to meet his death like a hare running down the throat of a python. Something called to them from the deeps of the forest, something the men call a loon, for lack of a better name, but only the doomed ones could hear it. Zogar Sag has made a magic that Aquilonian civilization can't overcome.'

To this thrust Valannus made no reply; he wiped his brow with a shaky hand.

'Do the soldiers know of this?'

'We left the body by the eastern gate.'

'You should have concealed the fact, hidden the corpse somewhere in the woods. The soldiers are nervous enough already.'

'They'd have found it out some way. If I'd hidden the body, it would have been returned to the fort as the corpse of Soractus was - tied up outside the gate for the men to find in the morning.'

Valannus shuddered. Turning, he walked to a cas.e.m.e.nt and stared silently out over the river, black and shiny under the glint of the stars. Beyond the river the jungle rose like an ebony wall. The distant screech of a panther broke the stillness. The night pressed in, blurring the sounds of the soldiers outside the blockhouse, dimming the fires. A wind whispered through the black branches, rippling the dusky water. On its wings came a low, rhythmic pulsing, sinister as the pad of a leopard's foot.

'After all,' said Valannus, as if speaking his thoughts aloud, 'what do we know - what does anyone know - of the things that jungle may hide? We have dim rumors of great swamps and rivers, and a forest that stretches on and on over everlasting plains and hills to end at last on the sh.o.r.es of the western ocean. But what things lie between this river and that ocean we dare not even guess. No white man has ever plunged deep into that fastness and returned alive to tell us what he found. We are wise in our civilized knowledge, but our knowledge extends just so far - to the western bank of that ancient river! Who knows what shapes earthly and unearthly may lurk beyond the dim circle of light our knowledge has cast?

'Who knows what G.o.ds are worshipped under the shadows of that heathen forest, or what devils crawl out of the black ooze of the swamps? Who can be sure that all the inhabitants of that black country are natural? Zogar Sag - a sage of the eastern cities would sneer at his primitive magic-making as the mummery of a fakir; yet he has driven mad and killed five men in a manner no man can explain. I wonder if he himself is wholly human.'

'If I can get within ax-throwing distance of him I'll settle that question,' growled Conan, helping himelf to the governor's wine and pushing a gla.s.s toward Balthus, who took it hesitatingly, and with an uncertain glance toward Valannus.

The governor turned toward Conan and stared at him thoughtfully.

'The soldiers, who do not believe in ghosts or devils,' he said, 'are almost in a panic of fear. You, who believe in ghosts, ghouls, goblins, and all manner of uncanny things, do not seem to fear any of the things in which you believe.'

'There's nothing in the universe cold steel won't cut,' answered Conan. 'I threw my ax at the demon, and he took no hurt, but I might have missed, in the dusk, or a branch deflected its flight. I'm not going out of my way looking for devils; but I wouldn't step out of my path to let one go by.'

Valannus lifted his head and met Conan's gaze squarely.

'Conan, more depends on you than you realize. You know the weakness of this province - a slender wedge thrust into the untamed wilderness. You know that the lives of all the people west of the marches depend on this fort. Were it to fall, red axes would be splintering the gates of Velitrium before a horseman could cross the marches. His majesty, or his majesty's advisers, have ignored my plea that more troops be sent to hold the frontier. They know nothing of border conditions, and are averse to expending any more money in this direction. The fate of the frontier depends upon the men who now hold it.

'You know that most of the army which conquered Conajo-hara has been withdrawn. You know the force left me is inadequate, especially since that devil Zogar Sag managed to poison our water supply, and forty men died in one day. Many of the others are sick, or have been bitten by serpents or mauled by wild beasts which seem to swarm in increasing numbers in the vicinity of the fort. The soldiers believe Zogar's boast that he could summon the forest beasts to slay his enemies.

'I have three hundred pikemen, four hundred Bossonian archers, and perhaps fifty men who, like yourself, are skilled in woodcraft. They are worth ten times their number of soldiers, but there are so few of them. Frankly, Conan, my situation is becoming precarious. The soldiers whisper of desertion; they are low-spirited, believing Zogar Sag has loosed devils on us. They fear the black plague with which he threatened us - the terrible black death of the swamplands. When I see a sick soldier I sweat with fear of seeing him turn black and shrivel and die before my eyes.

'Conan, if the plague is loosed upon us, the soldiers will desert in a body! The border will be left unguarded and nothing will check the sweep of the dark-skinned hordes to the very gates of Velitrium - maybe beyond! If we can not hold the fort, how can they hold the town?

'Conan, Zogar Sag must die, if we are to hold Conajohara. You have penetrated the unknown deeper than any other man in the fort; you know where Gwawela stands, and something of the forest trails across the river. Will you take a band of men tonight and endeavour to kill or capture him? Oh, I know it's mad. There isn't more than one chance in a thousand that any of you will come back alive. But if we don't get him, it's death for us all. You can take as many men as you wish.'

'A dozen men are better for a job like that than a regiment,' answered Conan. 'Five hundred men couldn't fight their way to Gwawela and back, but a dozen might slip in and out again. Let me pick my men. I don't want any soldiers.'

'Let me go!' eagerly exclaimed Balthus. 'I've hunted deer all my life on the Tauran.'

'All right. Valannus, we'll eat at the stall where the foresters gather, and I'll pick my men. We'll start within an hour, drop down the river in a boat to a point below the village and then steal upon it through the woods. If we live, we should be back by daybreak.'

3 The Crawlers in the Dark

The river was a vague trace between walls of ebony. The paddles that propelled the long boat creeping along in the dense shadow of the eastern bank dipped softly into the water, making no more noise than the beak of a heron. The broad shoulders of the man in front of Balthus were a blur in the dense gloom. He knew that not even the keen eyes of the man who knelt in the prow would discern anything more than a few feet ahead of them. Conan was feeling his way by instinct and an intensive familiarity with the river.

No one spoke. Balthus had had a good look at his companions in the fort before they slipped out of the stockade and down the bank into the waiting canoe. They were of a new breed growing up in the world on the raw edge of the frontier - men whom grim necessity had taught woodcraft. Aquilonians of the western provinces to a man, they had many points in common. They dressed alike - in buckskin boots, leathern breeks and deerskin shirts, with broad girdles that held axes and short swords; and they were all gaunt and scarred and hard-eyed; sinewy and taciturn.

They were wild men, of a sort, yet there was still a wide gulf between them and the Cimmerian. They were sons of civilization, reverted to a semi-barbarism. He was a barbarian of a thousand generations of barbarians. They had acquired stealth and craft, but he had been born to these things. He excelled them even in lithe economy of motion. They were wolves, but he was a tiger.

Balthus admired them and their leader and felt a pulse of pride that he was admitted into their company. He was proud that his paddle made no more noise than did theirs. In that respect at least he was their equal, though woodcraft learned in hunts on the Tauran could never equal that ground into the souls of men on the savage border.

Below the fort the river made a wide bend. The lights of the outpost were quickly lost, but the canoe held on its way for nearly a mile, avoiding snags and floating logs with almost uncanny precision.

Then a low grunt from their leader, and they swung its head about and glided toward the opposite sh.o.r.e. Emerging from the black shadows of the brush that fringed the bank and coming into the open of the midstream created a peculiar illusion of rash exposure. But the stars gave little light, and Balthus knew that unless one were watching for it, it would be all but impossible for the keenest eye to make out the shadowy shape of the canoe crossing the river.

They swung in under the overhanging bushes of the western sh.o.r.e and Balthus groped for and found a projecting root which he grasped. No word was spoken. All instructions had been given before the scouting-party left the fort. As silently as a great panther Conan slid over the side and vanished in the bushes. Equally noiseless, nine men followed him. To Balthus, grasping the root with his paddle across his knee, it seemed incredible that ten men should thus fade into the tangled forest without a sound.

He settled himself to wait. No word pa.s.sed between him and the other man who had been left with him. Somewhere, a mile or so to the northwest, Zogar Sag's village stood girdled with thick woods. Balthus understood his orders; he and his companion were to wait for the return of the raiding-party. If Conan and his men had not returned by the first tinge of dawn, they were to race back up the river to the fort and report that the forest had again taken its immemorial toll of the invading race. The silence was oppressive. No sound came from the black woods, invisible beyond the ebony ma.s.ses that were the overhanging bushes. Balthus no longer heard the drums. They had been silent for hours. He kept blinking, unconsciously trying to see through the deep gloom. The dank night-smells of the river and the damp forest oppressed him. Somewhere, near by, there was a sound as if a big fish had flopped and splashed the water. Balthus thought it must have leaped so close to the canoe that it had struck the side, for a slight quiver vibrated the craft. The boat's stern began to swing, slightly away from the sh.o.r.e. The man behind him must have let go of the projection he was gripping. Balthus twisted his head to hiss a warning, and could just make out the figure of his companion, a slightly blacker bulk in tbe blackness.

The man did not reply. Wondering if he had fallen asleep, Balthus reached out and grasped his shoulder. To his amazement, the man crumpled under his touch and slumped down in the canoe. Twisting his body half about, Balthus groped for him, his heart shooting into his throat. His fumbling fingers slid over the man's throat - only the youth's convulsive clenching of his jaws choked back the cry that rose to his lips. His fingers encountered a gaping, oozing wound - his companion's throat had been cut from ear to ear.

In that instant of horror and panic Balthus started up - and then a muscular arm out of the darkness locked fiercely about his throat, strangling his yell. The canoe rocked wildly. Balthus' knife was in his hand, though he did not remember jerking it out of his boot, and he stabbed fiercely and blindly. He felt the blade sink deep, and a fiendish yell rang in his ear, a yell that was horribly answered. The darkness seemed to come to life about him. A b.e.s.t.i.a.l clamor rose on all sides, and other arms grappled him. Borne under a ma.s.s of hurtling bodies the canoe rolled sidewise, but before he went under with it, something cracked against Balthus' head and the night was briefly illuminated by a blinding burst of fire before it gave way to a blackness where not even stars shone.

4 The Beasts of Zogar Sag

Fires dazzled Balthus again as he slowly recovered his senses. He blinked, shook his head. Their glare hurt his eyes. A confused medley of sound rose about him, growing more distinct as his senses cleared. He lifted his head and stared stupidly about him. Black figures hemmed him in, etched against crimson tongues of flame.

Memory and understanding came in a rush. He was bound upright to a post in an open s.p.a.ce, ringed by fierce and terrible figures. Beyond that ring fires burned, tended by naked, dark-skinned women. Beyond the fires he saw huts of mud and wattle, thatched with brush. Beyond the huts there was a stockade with a broad gate. But he saw these things only incidentally. Even the cryptic dark women with their curious coiffures were noted by him only absently. His full attention was fixed in awful fascination on the men who stood glaring at him.

Short men, broad-shouldered, deep-chested, lean-hipped, they were naked except for scanty loin-clouts. The firelight brought out the play of their swelling muscles in bold relief. Their dark faces were immobile, but their narrow eyes glittered with the fire that burns in the eyes of a stalking tiger. Their tangled manes were bound back with bands of copper. Swords and axes were in their hands. Crude bandages banded the limbs of some, and smears of blood were dried on their dark skins. There had been fighting, recent and deadly.

His eyes wavered away from the steady glare of his captors, and he repressed a cry of horror. A few feet away there rose a low, hideous pyramid: it was built of gory human heads. Dead eyes glared gla.s.sily up at the black sky. Numbly he recognized the countenances which were turned toward him. They were the heads of the men who had followed Conan into the forest. He could not tell if the Cimmerian's head were among them. Only a few faces were visible to him. It looked to him as if there must be ten or eleven heads at least. A deadly sickness a.s.sailed him. He fought a desire to retch. Beyond the heads lay the bodies of half a dozen Picts, and he was aware of a fierce exultation at the sight. The forest runners had taken toll, at least.

Twisting his head away from the ghastly spectacle, he became aware that another post stood near him - a stake painted black as was the one to which he was bound. A man sagged in his bonds there, naked except for his leathern breeks, whom Balthus recognized as one of Conan's woodsmen. Blood trickled from his mouth, oozed sluggishly from a gash in his side. Lifting his head as he licked his livid lips, he muttered, making himself heard with difficulty above the fiendish clamor of the Picts: 'So they got you, too!'

'Sneaked up in the water and cut the other fellow's throat,' groaned Balthus. 'We never heard them till they were on us. Mitra, how can anything move so silently?'

'They're devils,' mumbled the frontiersman. 'They must have been watching us from the time we left midstream. We walked into a trap. Arrows from all sides were ripping into us before we knew it. Most of us dropped at the first fire. Three or four broke through the bushes and came to hand-grips. But there were too many. Conan might have gotten away. I haven't seen his head. Been better for you and me if they'd killed us outright. I can't blame Conan. Ordinarily we'd have gotten to the village without being discovered. They don't keep spies on the river bank as far down as we landed. We must have stumbled into a big party coming up the river from the south. Some devilment is up. Too many Picts here. These aren't all Gwaweli; men from the western tribes here and from up and down the river.'
