The only established trade route through the Skarhelm mountains. The name dates back to before the dragonborn arrived and was for a family that lived in the gap for generations. . The gap was named for a family that once occupied the gap and provided lodging mid way and safe passage.
The dragonborn dislodged the family and took over guarding the pass. However, with the withdrawal of most of the dragonborn, the pass has become a no-man’s land and a fairly dangerous place. Caravans require heavily armed escorts to have a chance to arrive safely.
