The Calx Mountains are the tallest in the Kingdom of Men, and some of the tallest of the world. Because the fault line they're on is still moving, and they're still being weathered, they don't really change in height much. It's very dry up here, and many of the rocks are covered in sand or dust. Alpine forest dot the landscape here and there, and caves and overhangs are found occasionally. However, this region is victim to occasionally devastating earthquakes, being on a fault line.
