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 unencumbered. 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' sturdy 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 lifter. “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 Hell.

  “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 impassioned. 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 damnable 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.

  Chapter II: 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 shores. 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 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 shores 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, 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 massacre. 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 headpiece 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 passed 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 faces 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 glassy 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 ar
chers.

  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,” 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 casement 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 shores 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 be 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 gods 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 himself to the governor's wine and pushing a glass 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 Conajohara has been withdrawn. You know the force left 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 cannot 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 endeavor 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 Ta
uran.”

  “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.”

  Chapter III: 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 blue 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.
