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.
