 In an earlier concept, Rohan's capital region was called the King's Lands, of which the Folde was a sub-region to the south-east of Edoras.North of the Folde, the boundary between the East-mark and West-mark runs along the Snowbourn River and the Entwash.Most of the rest of Rohan's population is spread along the foothills of the White Mountains in both directions from the Folde.
