Metinna is one of the four largest provinces in the Nilfgaardian Empire. Because of its size, it enjoys relative autonomy. Located in the middle of the empire, it is bordered by the Great Sea in the west, Geso, to the east, the province of Nazair to the north and Maecht to the south. The region, one third of which is comprised of the plains of Mag Deira, is bounded to the north by the Yelena and to the south by the Sylte river.
