The Barrier Peaks spur eastward from the northern tip of the Crystalmists. The Joten Mountains are a small eastward spur in the south that separates Sterich and Yeomanry. At its southern end, the Crystalmists branch off into the Sulhaut Mountains and the Hellfurnaces.
The Crystalmists was home to several Dwarven Kingdoms who, for the most part, migrated elsewhere after a series of mountain wars that devastated their clans as well as the local giant population of Fire and Frost Giants.
The most notable peak of this range is Mount Rungnirheim which is the ancestral home of the local Frost Giants.
