The Misted Mountains are a range that border the country of Shinovar to its northeast, east and southeast. The range serves as a windbreak for the nation, weakening Highstorms, thereby protecting the land and it's inhabitants from the effects of these storms.
To the range's north lies the nation/kingdom of Iri; to its northeast, the country, Babatharnam; to its east, the country, Desh; to its southeast, the nation/kingdom of Yezier and the country, Alm.
Just as Robert Jordan's Mountains of Mist are a tribute to J.R.R. Tolkien, so too are Brandon Sanderson's Misted Mountains a similar tribute.
