In the distant east, cut off from the rest of the world by the heaving up of gigantic mountains and the forming of a chain of vast lakes, the Lemurians are toiling as slaves of their ancient masters. The far south is still veiled in mystery. Untouched by the Cataclysm, its destiny is still pre-human. Of the civilized races of the Thurian Continent, a remnant of one of the non-Valusian nations dwells among the low mountains of the southeast — the Zhemri. Here and there about the world are scattered clans of apish savages, entirely ignorant of the rise and fall of the great civilizations. But in the far north another people are slowly coming into existence.
At the time of the Cataclysm, a band of savages, whose development was not much above that of the Neanderthal, fled to the north to escape destruction. They found the snow-countries inhabited only by a species of ferocious snow-apes — huge shaggy white animals, apparently native to that climate. These they fought and drove beyond the Arctic circle, to perish, as the savages thought. The latter, then, adapted themselves to their hardy new environment and throve.
After the Pictish-Atlantean wars had destroyed the beginnings of what might have been a new culture, another, lesser cataclysm further altered the appearance of the original continent, left a great inland sea where the chain of lakes had been, to further separate west from east, and the attendant earthquakes, floods and volcanoes completed the ruin of the barbarians which their tribal wars had begun.
A thousand years after the lesser cataclysm, the western world is seen to be a wild country of jungles and lakes and torrential rivers. Among the forest-covered hills of the northwest exist wandering bands of ape-men, without human speech, or the knowledge of fire or the use of implements. They are the descendants of the Atlanteans, sunk back into the squalling chaos of jungle-bestiality from which ages ago their ancestors so laboriously crawled. To the southwest dwell scattered clans of degraded, cave-dwelling savages, whose speech is of the most primitive form, yet who still retain the name of Picts, which has come to mean merely a term designating men — themselves, to distinguish them from the true beasts with which they contend for life and food. It is their only link with their former stage. Neither the squalid Picts nor the apish Atlanteans have any contact with other tribes or peoples.
Far to the east, the Lemurians, levelled almost to a bestial plane themselves by the brutishness of their slavery, have risen and destroyed their masters. They are savages stalking among the ruins of a strange civilization. The survivors of that civilization, who have escaped the fury of their slaves, have come westward. They fall upon that mysterious pre-human kingdom of the south and overthrow it, substituting their own culture, modified by contact with the older one. The newer kingdom is called Stygia, and remnants of the older nation seemed to have survived, and even been worshipped, after the race as a whole had been destroyed.
Here and there in the world small groups of savages are showing signs of an upward trend; these are scattered and unclassified. But in the north, the tribes are growing. These people are called Hyborians, or Hybori; their god was Bori — some great chief, whom legend made even more ancient as the king who led them into the north, in the days of the great Cataclysm, which the tribes remember only in distorted folklore.
They have spread over the north, and are pushing southward in leisurely treks. So far they have not come in contact with any other races; their wars have been with one another. Fifteen hundred years in the north country have made them a tall, tawny-haired, grey-eyed race, vigorous and warlike, and already exhibiting a well-defined artistry and poetism of nature. They still live mostly by the hunt, but the southern tribes have been raising cattle for some centuries. There is one exception in their so far complete isolation from other races: a wanderer into the far north returned with the news that the supposedly deserted ice wastes were inhabited by an extensive tribe of ape-like men, descended, he swore, from the beasts driven out of the more habitable land by the ancestors of the Hyborians. He urged that a large war-party be sent beyond the arctic circle to exterminate these beasts, whom he swore were evolving into true men. He was jeered at; a small band of adventurous young warriors followed him into the north, but none returned.
But tribes of the Hyborians were drifting south, and as the population increased this movement became extensive. The following age was an epoch of wandering and conquest. Across the history of the world tribes and drifts of tribes move and shift in an everchanging panorama.
Look at the world five hundred years later. Tribes of tawny-haired Hyborians have moved southward and westward, conquering and destroying many of the small unclassified clans.
Absorbing the blood of conquered races, already the descendants of the older drifts have begun to show modified racial traits, and these mixed races are attacked fiercely by new, purer-blooded drifts, and swept before them, as a broom sweeps debris impartially, to become even more mixed and mingled in the tangled debris of races and tag-ends of races.
As yet the conquerors have not come in contact with the older races. To the southeast the descendants of the Zhemri, given impetus by new blood resulting from admixture with some unclassified tribe, are beginning to seek to revive some faint shadow of their ancient culture. To the west the apish Atlanteans are beginning the long climb upward. They have completed the cycle of existence; they have long forgotten their former existence as men; unaware of any other former state, they are starting the climb unhelped and unhindered by human memories. To the south of them the Picts remain savages, apparently defying the laws of Nature by neither progressing nor retrogressing. Far to the south dreams the ancient mysterious kingdom of Stygia. On its eastern borders wander clans of nomadic savages, already known as the Sons of Shem.
Next to the Picts, in the broad valley of Zingg, protected by great mountains, a nameless band of primitives, tentatively classified as akin to the Shemites, has evolved an advanced agricultural system and existence.
Another factor has added to the impetus of Hyborian drift. A tribe of that race has discovered the use of stone in building, and the first Hyborian kingdom has come into being — the rude and barbaric kingdom of Hyperborea, which had its beginning in a crude fortress of boulders heaped to repel tribal attack. The people of this tribe soon abandoned their horse-hide tents for stone houses, crudely but mightily built, and thus protected, they grew strong. There are few more dramatic events in history than the rise of the rude, fierce kingdom of Hyperborea, whose people turned abruptly from their nomadic life to rear dwellings of naked stone, surrounded by cyclopean walls — a race scarcely emerged from the polished stone age, who had by a freak of chance, learned the first rude principles of architecture.
The rise of this kingdom drove forth many other tribes, for, defeated in the war, or refusing to become tributary to their castle-dwelling kinsmen, many clans set forth on long treks that took them half-way around the world. And already the more northern tribes are beginning to be harried by gigantic blond savages, not much more advanced than ape-men.
The tale of the next thousand years is the tale of the rise of the Hyborians, whose warlike tribes dominate the western world. Rude kingdoms are taking shape. The tawny-haired invaders have encountered the Picts, driving them into the barren lands of the west. To the northwest, the descendants of the Atlanteans, climbing unaided from apedom into primitive savagery, have not yet met the conquerors. Far to the east the Lemurians are evolving a strange semi-civilization of their own. To the south the Hyborians have founded the kingdom of Koth, on the borders of those pastoral countries known as the Lands of Shem, and the savages of those lands, partly through contact with the Hyborians, partly through contact with the Stygians who have ravaged them for centuries, are emerging from barbarism. The blond savages of the far north have grown in power and numbers so that the northern Hyborian tribes move southward, driving their kindred clans before them. The ancient kingdom of Hyperborea is overthrown by one of these northern tribes, which, however, retains the old name. Southeast of Hyperborea a kingdom of the Zhemri has come into being, under the name of Zamora. To the southwest, a tribe of Picts have invaded the fertile valley of Zingg, conquered the agricultural people there, and settled among them. This mixed race was in turn conquered later by a roving tribe of Hybori, and from these mingled elements came the kingdom of Zingara.
