Cast in the mold of humanity, they were distinctly not men. They were winged and of heroic proportions; not a branch on the mysterious stalk of evolution that culminated in man, but the ripe blossom on an alien tree, separate and apart from that stalk. Aside from their wings, in physical appearance they resembled man only as man in his highest form resembles the great apes. In spiritual, esthetic and intellectual development they were superior to man as man is superior to the gorilla. But when they reared their colossal city, man's primal ancestors had not yet risen from the slime of the primordial seas.
These beings were mortal, as are all things built of flesh and blood. They lived, loved and died, though the individual span of life was enormous. Then, after uncounted millions of years, the Change began. The vista shimmered and wavered, like a picture thrown on a windblown curtain. Over the city and the land the ages flowed as waves flow over a beach, and each wave brought alterations. Somewhere on the planet the magnetic centers were shifting; the great glaciers and ice-fields were withdrawing toward the new poles.
The littoral of the great river altered. Plains turned into swamps that stank with reptilian life. Where fertile meadows had rolled, forests reared up, growing into dank jungles. The changing ages wrought on the inhabitants of the city as well. They did not migrate to fresher lands. Reasons inexplicable to humanity held them to the ancient city and their doom. And as that once rich and mighty land sank deeper and deeper into the black mire of the sunless jungle, so into the chaos of squalling jungle life sank the people of the city. Terrific convulsions shook the earth; the nights were lurid with spouting volcanoes that fringed the dark horizons with red pillars.
After an earthquake that shook down the outer walls and highest towers of the city, and caused the river to run black for days with some lethal substance spewed up from the subterranean depths, a frightful chemical change became apparent in the waters the folk had drunk for millenniums uncountable.
Many died who drank of it; and in those who lived, the drinking wrought change, subtle, gradual and grisly. In adapting themselves to the changing conditions, they had sunk far below their original level. But the lethal waters altered them even more horribly, from generation to more bestial generation. They who had been winged gods became pinioned demons, with all that remained of their ancestors' vast knowledge distorted and perverted and twisted into ghastly paths. As they had risen higher than mankind might dream, so they sank lower than man's maddest nightmares reach. They died fast, by cannibalism, and horrible feuds fought out in the murk of the midnight jungle. And at last among the lichen-grown ruins of their city only a single shape lurked, a stunted abhorrent perversion of nature.
Then for the first time humans appeared: dark-skinned, hawkfaced men in copper and leather harness, bearing bows-the warriors of pre-historic Stygia. There were only fifty of them, and they were haggard and gaunt with starvation and prolonged effort, stained and scratched with jungle-wandering, with bloodcrusted bandages that told of fierce fighting. In their minds was a tale of warfare and defeat, and flight before a stronger tribe which drove them ever southward, until they lost themselves in the green ocean of jungle and river.
Exhausted they lay down among the ruins where red blossoms that bloom but once in a century waved in the full moon, and sleep fell upon them. And as they slept, a hideous shape crept red-eyed from the shadows and performed weird and awful rites about and above each sleeper. The moon hung in the shadowy sky, painting the jungle red and black; above the sleepers glimmered the crimson blossoms, like splashes of blood. Then the moon went down and the eyes of the necromancer were red jewels set in the ebony of night.
When dawn spread its white veil over the river, there were no men to be seen: only a hairy winged horror that squatted in the center of a ring of fifty great spotted hyenas that pointed quivering muzzles to the ghastly sky and howled like souls in hell.
Then scene followed scene so swiftly that each tripped over the heels of its predecessor. There was a confusion of movement, a writhing and melting of lights and shadows, against a background of black jungle, green stone ruins and murky river. Black men came up the river in long boats with skulls grinning on the prows, or stole stooping through the trees, spear in hand. They fled screaming through the dark from red eyes and slavering fangs. Howls of dying men shook the shadows; stealthy feet padded through the gloom, vampire eyes blazed redly. There were grisly feasts beneath the moon, across whose red disk a batlike shadow incessantly swept.
Then abruptly, etched clearly in contrast to these impressionistic glimpses, around the jungled point in the whitening dawn swept a long galley, thronged with shining ebon figures, and in the bows stood a white-skinned ghost in blue steel.
It was at this point that Conan first realized that he was dreaming. Until that instant he had had no consciousness of individual existence. But as he saw himself treading the boards of the Tigress, he recognized both the existence and the dream, although he did not awaken.
Even as he wondered, the scene shifted abruptly to a jungle glade where N'Gora and nineteen black spearmen stood, as if awaiting someone. Even as he realized that it was he for whom they waited, a horror swooped down from the skies and their stolidity was broken by yells of fear. Like men maddened by terror, they threw away their weapons and raced wildly through the jungle, pressed close by the slavering monstrosity that flapped its wings above them.
Chaos and confusion followed this vision, during which Conan feebly struggled to awake. Dimly he seemed to see himself lying under a nodding cluster of black blossoms, while from the bushes a hideous shape crept toward him. With a savage effort he broke the unseen bonds which held him to his dreams, and started upright.
Bewilderment was in the glare he cast about him. Near him swayed the dusky lotus, and he hastened to draw away from it.
In the spongy soil near by there was a track as if an animal had put out a foot, preparatory to emerging from the bushes, then had withdrawn it. It looked like the spoor of an unbelievably large hyena.
He yelled for N'Gora. Primordial silence brooded over the jungle, in which his yells sounded brittle and hollow as mockery. He could not see the sun, but his wilderness-trained instinct told him the day was near its end. A panic rose in him at the thought that he had lain senseless for hours. He hastily followed the tracks of the spearmen, which lay plain in the damp loam before him. They ran in single file, and he soon emerged into a glade-to stop short, the skin crawling between his shoulders as he recognized it as the glade he had seen in his lotus-drugged dream. Shields and spears lay scattered about as if dropped in headlong flight.
And from the tracks which led out of the glade and deeper into the fastnesses, Conan knew that the spearmen had fled, wildly. The footprints overlay one another; they weaved blindly among the trees. And with startling suddenness the hastening Cimmerian came out of the jungle onto a hill-like rock which sloped steeply, to break off abruptly in a sheer precipice forty feet high. And something crouched on the brink.
At first Conan thought it to be a great black gorilla. Then he saw that it was a giant black man that crouched ape-like, long arms dangling, froth dripping from the loose lips. It was not until, with a sobbing cry, the creature lifted huge hands and rushed towards him, that Conan recognized N'Gora. The black man gave no heed to Conan's shout as he charged, eyes rolled up to display the whites, teeth gleaming, face an inhuman mask.
