According to the tale, more than 10,000 years ago, a race of shepherd people colonized the banks of the river Ai in a land called Mnar, forming the cities of Thraa, Ilarnek, and Kadatheron (not to be confused with Kadath), which rose to great intellectual and mercantile prowess. Craving more land, a group of these hardy people migrated to the shores of a lonely and vast lake at the heart of Mnar, founding the metropolis of Sarnath.
