ORIGIN AND HISTORY
Kath histories are oral and consequently vague. It seems they once dwelt near the wear coast of Lythia in present day Quarphor. Some 1500-2000 years ago, great waves of barbarians migrations occurred throughout western Lythia. Horde after horde of eastern nomads passed through Kath lands on their way to the sea or to ravage other lands. There was a constant state of war and the Kath tired of it. Legend recounts that a leader called Pahris (c. 800 BT) gathered the surviving Kath and led them out to the sea in a flotilla of small craft. Many were lost as they sailed west across the Sea of Ivae to land in Garvin Bay on Harn's east coast. This inhospitable region was not to their liking, so within a few years they undertook another great trek inland across the Sorkin Mountains. Many were lost to the rugged terrain and harsh weather. A few hundred completed the journey and came at last (c. 780 BT) to fertile Upper Kald Valley. After a skirmish or two with the Jarin farmers who had previously settled this region, most Kath accepted a negotiated peace and chose to stay in the valley. A few dozen were not inclined to the settled lifestyle; they crossed the Kald and occupied the empty highlands to the west which now bears their name, "The Kathela Hills".
The Kath who settled among the Jarin were known as the Low Kath; those who chose the highland range called themselves the High Kath. The Low Kath were largely assimilated by the more advanced Jarin and adopted their pastoral/agrarian culture. The High Kath clung to their hunting-gathering traditions, finding the Kathela Hills paticularly abundant in berries and wildlife. As the centuries passed in relative peace the High Kath began to think of themselves as the true Kath. The considered their more primitive ways to be cherished traditions. By the time of Lothrim, the low Kath did not really exsist as a recognizable culture but High Kath identity was stronger then ever.
