Trakor, youthful member of the tribe of Gerdak, moved at a swinging trot along a winding game trail that led to the caves of his people. Through occasional rifts in the matted mazes of branches, leafs, creepers and vines of the semi-tropical forest and jungle, rays of the late afternoon sun dappled the dusty elephant path under his naked feet.

His slim young body, clothed only by the pelt of Jalok, the panther, twisted about his loins, was bathed in perspiration, for both heat and humidity were intense here in the heart of primeval jungle. From time to time he transferred the flint-tipped spear to his left hand while he rubbed dry the sweating palm of his right against his loin cloth; for a slippery spear shaft could mean the difference between life and death in a battle with some savage denizen of this untamed world.

Trakor was beginning to worry. There was less than an hour of daylight remaining and he was still a long way from home. The thought of spending even a small portion of a night alone in a territory that abounded in lions, panthers, leopards and the other fearsome creatures of forest and plain, sent shivers of dread coursing along his spine.

And there was no one but himself to blame for this predicament! A boy of seventeen had no business attempting a task that would have given an older, more experienced warrior pause. Only a fool, he told himself bitterly, would have gone forth alone to hunt without having first gained experience by many trips in the company of seasoned hunters, thus learning the habits of the wild creatures.

It was all Lanoa's fault! In the soft fragrance of midnight hair curling about the tanned oval of her lovely face, in the smoothly rounded perfection of her slender body, in the golden depths of her clear, glowing eyes, were the seeds of madness that had sent him forth on a fool's errand! Before coming under her spell he was content to spend his days learning from old Wokard the art of painting scenes of tribal life and the hunt on the walls of the caves of his people.

Not until he watched Lanoa's other suitors displaying the trophies of the hunt did young Trakor make his decision to lay aside his paints and venture out in search of game. For it was easy to see how greatly Lanoa was impressed by the boastful tales of the other young men.

But where they hunted in groups, for safety's sake, Trakor would go out alone after Neela, the zebra, or Bana, the deer. And when Lanoa saw him return to the caves of Gerdak with the carcass of Neela across his shoulders, his heavy spear trailing from a casual hand, then would she realize that of all the young men of the tribe it was Trakor who was best suited to be her mate!

Thus the stuff of dreams ... and how different the reality! Since early morning of this day he had wandered through the forest and across wide stretches of prairie, seeking any of the various species of succulent grass-eaters that served as the principal fare of the Cro-Magnons. And while he had caught sight of grazing herds on several occasions, his utter lack of experience in the art of stalking prevented him from coming anywhere near enough for a successful spear cast.

Now he was slinking back home empty handed to face the gibes of those he had thought to impress, while the light of day gradually waned and the dark shadows of the jungle grew heavier across his path.

But the boy's wounded pride began to trouble him less as the certainty that he must spend a night in the open became increasingly evident. The everyday noises of the jungle, so nerve-wracking to those unable to interpret them, yet unnoticed by the jungle-wise, kept him in a constant state of apprehension while his fertile imagination pictured lurking shapes crouched behind the wall of tangled underbrush lining either side of the trail.

Without warning, the narrow path debouched into a fair-sized clearing, through the center of which moved the sluggish waters of a shallow stream, its low banks covered with reeds.

Compared with the dull half-light of jungle depths, the glade seemed bright as midday, although the sun had already dipped behind the towering rampart of trees to the west. Trakor's heart swelled with renewed confidence and his step was almost jaunty as he moved through the knee-deep grasses and rustling reeds to the river bank.

Now he knew exactly where he was. Another hour at a half-trot would bring him to the caves of Gerdak. The jungle wasn't such a fearsome place after all! He had spent an entire day in the open and not once come across anything more dangerous than monkeys and birds. Tomorrow he would go out again to hunt, nor would he return empty-handed a second time.

Dropping to his hands and knees at the river's edge, he drank deeply of the brackish waters. Rising, he took up his spear, waded the ankle-deep stream and trotted lightly onward, his goal the break in the opposite wall of trees which marked the continuation of the same trail he had been following.

Thus did young Trakor betray his abysmal ignorance of the jungle and its inhabitants. No experienced wayfarer of the wild places would have approached that opening without the utmost caution; for it is often just such a setting the great cats choose as a place to lie in wait for game.

The slender youth was within a few feet of the bole of a mammoth tree that marked the trail's entrance, when a sudden rustling amid a clump of grasses to one side of the path brought him to a startled halt.

Before Trakor could recover from his initial shock, those trembling grasses parted, and with majestic deliberation, Sadu, the lion, stepped into the trail less than twenty paces from the paralyzed youngster.

Huge, impressive, his sleek, tawny coat and bristling mane shimmering in the fading sunlight, his tufted, sinuous tail moving in jerky undulations, stood the jungle king, his round yellow eyes fastened hypnotically on his intended prey.

Trakor knew that only seconds remained for him in this life, that within fleeting moments he must go down to a horrible death beneath rending fangs.

And with that knowledge came a fatalistic courage—a courage he had not dreamed he possessed. With icy calmness he closed the fingers of his right hand tightly about the shaft of his spear and brought it up level with his shoulder, point foremost, ready for a cast when the great beast should charge.

Slowly Sadu crouched for the spring, his giant head flattened almost to the ground, massive hindquarters drawn beneath him like powerful springs, his long tail extended and quivering.

Voicing a thunderous roar, Sadu sprang.

Racing across the plains and through the jungles of a savage world, moving with unflagging swiftness by night and by day, came Tharn, mighty warrior of an era already old twenty thousand years before the founding of Rome—an era which witnessed the arrival to recognizable prehistory of the first true man.

Somewhere to the south of this Cro-Magnon fighting man, separated by endless vistas of primeval forest, grass-filled plains and towering mountain ranges, were the girl he loved and the men who had taken her.

Still fresh in Tharn's memory were the events of the past few weeks: the battles in Sephar's arena; the bloody revolt engineered by Tharn and his friends; the arrival of his father and fifty warriors of his tribe; the ascension of his close friend, Katon, to the kingship of Sephar; the finding of his own mother, long given up for dead after disappearing from the tribal caves ten summers before; the stunning shock upon learning that Jotan had taken Dylara with him when he and his party of fellow Ammadians began their journey back to far-off Ammad, mother country of a civilization and culture far in advance of the Cro-Magnon cave dwellers.*

* "Warrior of the Dawn", December, 1942-January, 1943, Amazing Stories.—Ed.

The thrust of a knife from the cowardly and treacherous hand of Sephar's high priest had come near to costing Tharn his life on the eve of his departure in quest of Dylara. As it was, an entire moon passed before the caveman was able to leave his bed.

Pryak, the high priest, had died horribly in payment of his treachery; but Tharn suffered a thousand deaths from enforced idleness while the girl he loved was being carried farther and farther from the one person who possessed the ability to effect her rescue.

And then, over a moon ago, Tharn bade farewell to his mother and to the father whose name he bore, and plunged into the heart of the unfamiliar territory south of Sephar, taking up the trail of those Ammadians who held Dylara.

Near sunset of this particular day, Tharn awoke from a nap, as it was his practice during the baking heat of mid-afternoons. By thus conserving his strength during the more trying portion of the days, he was able to spend many hours after nightfall, when the air was cooler, in pursuit of his quarry.

Rising to his feet on a softly swaying branch a full hundred feet above the jungle floor, Tharn flexed the mighty muscles of arms and legs, his naked chest swelling as he drew in great draughts of humid atmosphere. The slender fingers of his strong, sun-bronzed hand pushed back the shock of thick black hair crowning his finely shaped head and strikingly handsome features, while the flashing, intelligent gray eyes roved quickly over the mazes of foliage surrounding him.

Nor was it his eyes alone that probed those curtains of growing things; ears and a nose keen as those of any jungle dweller were no less active.

He was on the point of descending to the game trail below when Siha, the wind, brought to his sensitive nostrils the scent of man commingled with the acrid smell of Sadu, the lion.

For the space of a dozen heartbeats he stood there, high above the hard-packed earth, while his keen mind rapidly analyzed the message his nose had picked up. From the strength of those scents he knew both man and beast were not far away, while the direction of the breeze told him their position.

Since the day Tharn, the son of Tharn, set out in search of the girl he loved, he had encountered men on several occasions and always those meetings were unpleasant. The Cro-Magnon tribes inhabiting the mountain ranges between Sephar and the land of Ammad were distinguished by their ability as fighters and an unflagging suspicion of strangers. Were it not for Tharn's tremendous strength and incredible agility, he would have died long ere this.

Consequently his first reaction was to let Sadu and the unknown man settle their impending quarrel without his own intervention. But a basic part of Tharn's character was his ready willingness to come to the aid of the underdog, to champion the cause of the weak and oppressed. It was a trait which had brought him to the brink of disaster more than once; but Tharn, were he to have given the matter any thought at all, would not have had it otherwise.

Thus it was that the caveman altered his course to the east and he set off through the trees, swinging among the branches with the ease and celerity of little Nobar, the monkey. Now and then, with the agility of long practice, he sent his lithe body hurtling across some gap between trees, to grasp with unerring accuracy the limb his quick eye had selected. Yet notwithstanding his seemingly reckless pace his passage was almost soundless; and though the tangled verdure appeared as a solid wall, only rarely did his flying figure scrape against the riot of vegetation hemming him in.

A few minutes later the giant Cro-Magnard swung into the branches of a tree at the edge of a large circular clearing. Even as he reached the broad surface of a bough extending over the floor of the open ground, he caught sight of his old enemy, Sadu, the lion, crouching in the trail almost directly beneath him. Simultaneously he saw Sadu's intended prey: a slender Cro-Magnon youth, some four years younger than Tharn himself, who was standing stiffly erect, facing the lion, a flint-tipped spear poised in his right hand.

Tharn felt himself thrill to the boy's unflinching courage even as he recognized its futility, since no human could thus withstand the iron-thewed engine of destruction that was Sadu, the lion.

Tharn was given no opportunity to make use of his arrows or grass rope; for even as he observed the two figures below, the lion's tail shot stiffly erect, a shattering roar split apart the jungle stillness and Sadu charged.

As a swimmer dives from a springboard, so did Tharn launch himself into space, his right hand snatching the flint knife from the folds of his loincloth as he left the branch.

Never before had the cave lord thus attacked the king of beasts; but never before had he sought to wrest Sadu's prey, unharmed, from the animal's fangs and claws. As it was, he landed full upon the lion's back, crushing the beast to earth only inches short of its goal.

Voicing a startled shriek, Sadu rebounded from the forest floor like a tawny ball and turned to rend his foolhardy attacker.

Tharn, however, was not on the ground. His mind, trained from birth to function with lightning-like rapidity, had chosen the only way to prevent his unplanned act from resulting in certain death for himself. And so it was, as his diving body crushed Sadu to the ground, he passed his strong left arm about its neck, locked his powerful legs about its loins, and plunged his flint knife into its side, seeking the savage heart.

Roaring, snarling and spitting in a frenzy of rage, Sadu reared high and toppled back upon the human leech. But Tharn's legs locked only the tighter while the heavy knife, backed by biceps like banded layers of steel, sank home again and again.

Had the battle endured seconds longer the outcome might very well have been reversed. But before then Tharn's weapon tore twice into that untamed heart, and Sadu, with a final fearsome shriek, collapsed to move no more.

As Tharn rose to his feet, his calm gray eyes met the awed, half-mesmerized gaze of the boy whose life he had saved. At sight of the incredulous expression on the young face, the cave lord's firm lips curved in a winning smile that lighted up his strong, noble features.

As for Trakor, he could not have moved or spoken had his life depended on it. There was no doubt in his mind but that he was in the presence of one of the gods old Wokard often described. Who else but a god could slay Sadu with only a knife; who else but a god could possess such a combination of inhuman strength and unbelievable agility? The noble poise of that handsome head above broad shoulders, the soft sinuous curves of that straight and perfect figure, the unclouded bronze skin, the calm dignity of bearing and manner—all those things were attributes of the benign gods who watched over and protected the people of Gerdak's tribe.

Tharn's smile broadened as he guessed something of what was running through the boy's mind.

"Do you," he asked, "hunt often for Sadu with only a spear?"

Trakor shivered. "I would not hunt him with a forest of spears! When he came out of the grasses my blood turned to water and my toes crawled under my heels. Now I know what it is to be afraid!"

"You should have taken to the trees while I fought with Sadu," Tharn said. "Had he killed me, he would have slain you as well."

"Even Sadu cannot kill a god," the boy said simply.

Tharn blinked. "A god? I am no god. I am Tharn, a man of the caves, like you."

Trakor, while tremendously flattered at being compared with the stranger, was far from convinced that Tharn was telling the truth.

"A caveman could not slay Sadu thus," he declared, pushing a bare toe gingerly against the dead beast's back. "No, you are a god, for gods have been described to me many times by old Wokard, who knows all about such things."

The giant Cro-Magnard shrugged, smiling, and sought to change the subject. "Who are you?" he asked.

"I am Trakor, of the tribe of Gerdak."

"The caves of your people are nearby?"

"An hour's march in that direction," Trakor said, pointing.

Tharn's eyebrows lifted in surprise. "So far? Do you often go alone this deep into the jungle?"

Whereupon Trakor found himself telling the forest god the whole story: how the raven-haired Lanoa had shown, by her admiration for the young hunters of the tribe, that she would never become the mate of a man who did not excel in the hunt; how he was determined to prove to her and to the others of Gerdak's tribe that he too was a great hunter.

Tharn listened with grave attention, and while there were times when he was tempted to smile at some unconscious revelation of the boy's character, he resisted the impulse. It required courage to venture alone into the forest armed only with a spear. The soul of an artist, as revealed by Trakor's love of painting, had clashed with the hot blood of youth and a desire to appear to advantage in the eyes of a lovely woman. Older and more conservative men than Tharn would have named Trakor's act sheer lunacy; but Tharn was neither old nor conservative. Under the circumstances he would have done exactly the same thing.

When Trakor was finished, Tharn said, "There will be other days for hunting. Unless you are willing to travel the jungle at night, you had best start for the caves of Gerdak."

Trakor sought to hide his apprehension as he looked about the dusk-filled glade and back to the dark hole which marked the game trail entrance.

"You are right," he said, turning to the cave lord. "I am grateful to you for saving me from Sadu, mighty Tharn. Who knows but that someday I may be of help to you."

"Who knows?" Tharn repeated gravely.

He remained standing there as Trakor turned and walked briskly toward the wall of foliage to the south. The boy's shoulders were squared and his brown-thatched head erect as he moved away, and Tharn felt a warm glow of admiration at the fierce pride that would not let its owner ask for further protection. For he knew that secretly Trakor dreaded the thought of traversing the final stretch of night-shrouded jungle.

Purposely he waited until the youth was nearly out of sight, to learn if, at the last moment, Trakor's step might falter or his head turn for one last appealing glance. But the boy forged steadily ahead....

"Wait, Trakor," Tharn called.

The youth turned quickly and watched as Tharn gathered up his bow, quiver of arrows and grass rope from where they had fallen when he leaped to do battle with Sadu. With his weapons restored to their usual places, the caveman rejoined Trakor at the forest's edge.

"Since my way lies in the same direction," Tharn said, "I will go with you for a time."

"Good," Trakor said laconically. He might have said more, but he doubted the steadiness of his own voice, so great his relief.

Side by side they moved briskly along the winding trail, while the gloom of early night grew amidst the semi-tropical depths of forest and its inextricably tangled maze of branches, vines and creepers.

In some way these two members of the first race of true men to trod the globe were much alike; in others, as different as day from night. In age Tharn was no more than four years beyond his companion; in height perhaps an inch taller. Both were darkly tanned and each was clothed only by a loin-cloth of panther skin.

But there the similarity ended. Where Trakor was slender and with muscles not yet fully developed, Tharn's bronzed body was sheathed in supple sinews that rippled like steel cables beneath smooth skin. There was an undefinable surety, a boundless confidence, reflected in the graceful majesty of his expression and bearing. Unconsciously Trakor sought to carry himself in a like manner, for he was deep in the throes of hero worship.

"Tell me, Tharn," Trakor said diffidently, at last, "are you not truly a god?"

"It might be," Tharn said lightly. "Since I have never met a god, I would not know."

Trakor thought over the answer for a while. It did not seem that a real god such as old Wokard described would speak so of himself. Could it be that his new found friend, for all his superhuman abilities, was actually an ordinary man, just as he had claimed from the first?

Well, man he might be, but never an ordinary one!

"I am glad you are a man, Tharn," he said finally. "I do not think I would like to know a god."

"Nor would I," Tharn agreed soberly.

They moved rapidly ahead for a time, neither speaking. Suddenly the thunderous challenge of a lion rose from the depths of jungle not far to their right. Trakor shivered slightly and shot a quick glance at his companion. It was too dark for him to make out Tharn's expression but he seemed entirely unmoved by the sound of Sadu's voice.

A moment later Trakor heard the rustle of something moving in the undergrowth beside the trail, and a prickly sensation crawled along his spine. Sadu was hunting again! He would have liked to call Tharn's attention to the faint sound but hesitated to do so lest he appear overly nervous. Again came the slight rustle.

"It is Gubo, the hyena," Tharn said unexpectedly.

Trakor gasped. "How do you know that?" he demanded, both relieved and bewildered.

"He is upwind from us."

"Upwind? You mean you can scent him?"

"Yes."

The young man from the tribe of Gerdak nearly betrayed his skepticism. Never before had he heard of a man whose nose could receive and interpret a scent spoor. It smacked of a kinship with the animals themselves.

"Are you sure?" he asked uneasily.

Tharn's quick ear caught the undercurrent of incredulity in the boy's voice, and he smiled under the cover of darkness. It was not the first time his unique ability had been doubted. He drew Trakor to a halt.

"Watch," he said.

Lifting his head the cave lord gave voice to the hunting squall of a leopard. So perfect was his imitation of Tarlok's cry, so fearsome the sound, that Trakor shrank back in quick alarm.

As the harsh scream rose on the night air, there was a sudden flurry of motion among the tangled foliage to their right, a blurred figure skidded into the trail ahead of where they stood and disappeared around a bend of the path. In the brief moment in which it was visible, Trakor recognized the animal as Gubo.

Crestfallen, Trakor could think of nothing to say. Never again, he resolved, would he doubt any statement made by this god-like stranger. There were many questions he burned to ask, but an aura of reserve seemed to surround the man—an aura he hesitated to intrude upon. At last he could contain his curiosity no longer.

"Where lie the caves of your people, Tharn?"

"Nearly two moons' march to the north," the cave lord replied readily enough.

"You came so great a distance alone?"

"Yes."

"Why?"

Tharn did not at once reply. During the moon since he had set out from Sephar in search of Dylara this was his first opportunity for a friendly word with a fellow man. On the several occasions that he encountered hunting parties of Cro-Magnon warriors, he had been regarded as legitimate prey to be hunted down and slain. Tharn expected no different attitude; it was the way of his own people when they came across fighting-men of other tribes. Consequently he gave such groups a wide berth, fighting against them only when given no other choice.

Long periods of silence, however, were no hardship to Tharn. Since boyhood he was accustomed to spending most of his days and many nights alone in the jungles and on the broad plains of this savage, untamed world, finding his greatest pleasure in matching his courage, cunning and strength against the denizens of forest and prairie. And because none of the other young men of his father's tribe was so highly developed mentally or physically, he made no intimates among them.

It was the kind of life which tends to develop a reticent nature in any man; and while Tharn was in no way morose or antisocial he was given to saying little beyond what must, of necessity, be put into words.

Under the warmth of Trakor's awed respect and undisguised admiration, however, Tharn's customary reserve began to thaw and he spoke at greater length than he intended.

"Two moons ago," he began, while they moved steadily along the twisting elephant path, "the girl I wanted as my mate was taken by a group of men who called themselves Ammadians. These men came from a great territory that lies south of your own caves. Ages ago many hundreds of the Ammadians left their country and traveled into the north, stopping finally in a high valley only a few marches from where the caves of my people now are."

"Here they built many strange caves on level ground by piling heavy slabs of rock together, surrounding them all by a great wall of stone. They named this place Sephar and spoke of themselves as Sepharians."

"From time to time bands of Ammadians cross the plains and mountains and jungles between Ammad and Sephar. The leader of one of those bands, an Ammadian named Jotan, saw Dylara and wanted her for himself. Not long before this, Dylara had been taken from me by a hunting party of Sepharians, and she was held captive by Sephar's chief until he gave her to Jotan."

"Soon thereafter Jotan's party set out on the return journey to Ammad. Because of a wound, it was an entire moon before I was able to set out in pursuit of those who hold Dylara."

So engrossed was Trakor in the other's story that he quite forgot his uneasiness regarding the night-cloaked jungle about him. His imagination was fired by Tharn's adventures, and his ready sympathy went out to the cave lord in his romantic quest.

"Then you must enter the land called Ammad and take Dylara from those who have her?" he asked.

Tharn nodded. "At first," he said, "I hoped to overtake Jotan and his men before they could reach Ammad. But several times I lost their trail for days on end. Once a raging fire swept over a great stretch of grasslands I was crossing and I was forced to spend many days circling the burned section before I was able to pick up the signs of their passage. Then, ten suns ago, I lost the trail completely; since then I have been guided only by the directions given me when I left Sephar."

For a little while Trakor did not speak. Then: "Are these men you call Ammadians not so large as the people of our tribes? Do they cover their bodies with a strange kind of skin that comes from no animal? And do they wear strange coverings on their feet? And do they carry a strange length of branch with a tight length of gut tied to each end and many small spears such as you are carrying?"

Tharn, his pulses suddenly beginning to pound, seized the boy by one arm, bringing him to an involuntary halt. "Such are the Ammadians," he said tensely. "What do you know about them?"

"I have heard the warriors of my tribe speak of them," Trakor said. "There have been times in the past when we fought them. But they are brave and good fighters and we do not have the gut-strung branches which throw the small spears so straight and so far. So now we seek no quarrel with them unless they come too near our caves."

"Why, it was no more than five suns ago that Roban, son of Gerdak himself, watched a large party of them as they made their way up the great cliffs not far to the east of our caves. I heard him tell about it at the cooking fires that same night."

"Did he speak of women being among them?" Tharn demanded.

Trakor scratched his head. "I do not think so. As I remember it now, I did not hear the whole story; for Lanoa walked away from the fires and I followed her before Roban had finished."

Tharn's hand dropped from the boy's arm. "Come," he said, and once more they set out along the path.
