The Ugarat Odhan was a desert on the central part of the continent of Seven Cities. It was bordered on the north by the Thalas Mountains, to the south by the Jhena Mountains and Clatar Sea, to the east by the Mersin river, and to the west by Olphara Forest and the Jhag Odhan. The Odhan itself was named after the holy city located on it, Ugarat.
It was once fertile plains and forests, but the cities lining the Mersin river practiced intensive irrigation, drawing the river’s waters out onto the plains and clearing the forests. This led to the loss of the top-soil of the plains and made the area a desert.
