Daare Karsha

The Daare Karsha people, sometimes called Karathandis, are the human inhabitants of the Kesh Karkhan: The harsh and arid deep interior of the Orithean continent. They do not worship the Thaedonu-Vaati for the most part, and they speak a family of languages that is unintelligible to Tuvai speakers. This, together with their tribal social structures and often nomadic or semi-nomadic traditions, causes most Oritheans from outside the Kesh Karkhan to view them as barbarians or half-civilized at best. 
“Daare Karsha” means simply “inhabitants of the basins”, from the same archaic Tuvai word “kar” (a desert basin or wasteland) that appears in the name of the Kesh Karkhan and its major features like the Kar Kadash. “Karathandis” stems from the same root and means “basin-crossers” or “those who traverse the basins,” a reference to the nomadic habits of many of these tribes (or at least their ability to travel with apparent ease through landscapes that outsiders often find harsh and forbidding). 
Both are blanket terms used by Tuvai speakers for many different tribes living in this vast region. In truth these various tribes are a diverse group and do not think of themselves as a unified race or tribal family in the way the “civilized” Oritheans view them; members of two tribes from different parts of the Kesh Karkhan might consider themselves as foreign from each other as they are from, say, Kelims or Uremites. Nevertheless it is true that they speak a set of tribal languages which, if not all mutually intelligible, are at least all clearly descended from a common root. They also at least arguably share a certain set of physical characteristics, albeit with wide variation. Thus there may be some germ of truth to Tuvai-speakers lumping them all together under a single name and considering them a distinct people.
Scholars of ancient history speculate that the Daare Karsha are descended from those kindreds who migrated north in the early proto-archaic era, shortly after the first humans left Ulshanru, rather than settling around the Sarpic Seas as did the founders of the first known human civilizations. These wayward wanderers, the theory goes, spread out into the barren lands of the Kesh Karkhan, settling in the harsh deserts and craggy badlands, slowly forgetting Utara-Vaati and the ancestral gods of mankind. Over the ages their language changed from the shared proto-archaic Tuvai of all early humans to the various tribal tongues they now speak, much as (for instance) the Chomarra language has its roots in ancient Tuvai but has changed so much over the millennia that it is no longer at all intelligible to modern Tuvai speakers.
