"A forest devil. This is the fourth, by Crom!"

"What do you mean?"

"Did you ever hear of a Pictish wizard called Zogar Sag?"

Balthus shook his head uneasily.

"He dwells in Gwawela, the nearest village across the river. Three months ago he hid beside this road and stole a string of pack-mules from a pack-train bound for the fort drugged their drivers, somehow. The mules belonged to this man " Conan casually indicated the corpse with his foot "Tiberias, a merchant of Velitrium. They were loaded with ale kegs and old Zogar stopped to guzzle before he got across the river. A woodsman named Soractus trailed him, and led Valannus and a couple of soldiers to where he lay dead drunk in a thicket. At the importunities of Tiberias, Valannus threw Zogar Sag into a cell, which is the worst insult you can give a Pict. He managed to kill his guard and escape, and sent back word that he meant to kill Tiberias and the four men who captured him in a way that would make Aquilonians shudder for centuries to come.

"Well, Soractus and the soldiers are dead. Soractus was killed on the river, the soldiers in the very shadow of the fort. And now Tiberias is dead. No Pict killed any of them. Each victim except Tiberias, as you see lacked his head which no doubt is now ornamenting the altar of Zogar Sag's particular G.o.d."

"How do you know they weren't killed by the Picts?" demanded Balthus.

Conan pointed to the corpse of the merchant.

"You think that was done with a knife or a sword? Look closer and you'll see that only a talon could have made a gash like that. The flesh is ripped, not cut."

"Perhaps a panther " began Balthus, without conviction.

53.

Conan shook his head impatiently.

"A man from the Tauran wouldn't mistake the mark of a panther's claws. No. It's a forest devil summoned by Zogar Sag to carry out his revenge. Tiberias was a fool to start for Velitrium alone, and this close to dusk. But each one of the victims seemed to be smitten with madness just before doom overtook him. Look here; the signs are plain enough. Tiberias came riding along the trail on his mule, maybe with a bundle of choice otter pelts behind his saddle to sell in Velitrium, and the thing sprang on him from behind that bush. See where the branches are crushed down.

"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 h.e.l.l, 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 54.

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 woodman's axe 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 axe. 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 b.a.s.t.a.r.d, 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 seemed to blur 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 shudderingly 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!"

55.

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, flitting 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 axe 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 56.

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 leather loop and stalked down the trail.

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 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. This was no empty phrase. Fort Tuscelan was indeed 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 57.

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 torch-light flickered, glinting on a steel head-piece and suspicious eyes beneath it.

"Open the gate," snorted Conan. "You see it's me, 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 loop-holes 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 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 surprized 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-chiselled 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."

58.

"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's made a magic Aquilonian civilization can't overcome."

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

59.

"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 seemed pressing 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 axe-throwing distance of him I'll settle that question," growled Conan, helping himself 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."
