Ulshanru

Ulshanru, sometimes Ulshanor, Ul-Shanor, or Ul-Shanara, is the mythical, long-lost cradle of mankind where the first human beings, the Unbegotten Men, supposedly dwelt after being created by the Sons of Thaedon. Its name means “Abode of the Firstborn” in archaic Tuvai. Its exact location and characteristics are unknown to the generations of latter days; fragments of surviving texts from before the Schism Wars, over five thousand years before the present time, suggest that even the religious scholars of that archaic age regarded it as a lost and legendary place. Depictions and descriptions of Ulshanru thus vary widely and must be mostly regarded as fanciful; the inventions of latter-day poets and artists, or the speculations of scholars and scribes with little concrete basis.  
It is known that Ulshanru must have been in Orithea, probably (although not necessarily) somewhere around the shores of the western Sarpic Seas, since that is where the first known human civilizations arose. Scholars presume that some of the descendants of the Unbegotten Men, when they emerged from Ulshanru at the dawn of the the proto-archaic era, would have settled nearby and eventually founded these civilizations (probably after a long, but unknown, period of primitive subsistence), while others spread out further in other directions. The latter, migrating across Orithea to distant lands and forgetting Utara-Vaati, would eventually become the forebears of "savage" peoples like the Daare Karsha and the Thelbirs. 
Descriptions of Ulshanru generally provide that it was a warm, lush, and verdant place, idyllic, green and fruitful with sweet running waters, a shadow of Aenuvion on earth; and indeed this much is supported by glimpses of revelation that the gods have granted to certain favored priests and holy seers. Some have said it was an island in the midst of a placid lake; others a great garden watered by many springs, or a green land between two rivers. Some scholars have attempted to associate Ulshanru with various known places in modern Orithea; others say that the gods must have wiped it from the face of Urva after humans departed from it, or that it was destroyed in the great upheavals and earthquakes that tormented the lands around the Sarpic Seas at the end of the Schism Wars.
