The Sunset Mountains are a pair of mountain ranges separated by the Far Hills, which are literally part of their chain. They form a high, almost impenetrable barrier between the Eastern and Western Heartlands as well as the eastern edge of Sunset Vale.
These mountains are home to a large number of evil tribes and savage humanoids. Several small dwarven clans also live in this region. The dwarfs are very secretive about the exact location of their homes. Most of these dwarfs trade in the town of Easting.
The other humanoids are the Yeti, Gnoll, Ogre and Drow races. One White dragon had been recorded in Sunset Mountain history.
