The Orston cleft is bracketed by two hill ranges in the south east of Dunland.
It is the home to a nomadic horse people, originally from the Dunai tribes.
It also contains a salt mine, maintained by ancient servitors of the Atheviri, those approaching the mine are attacked on sight. However the servitors continue to stack the reclaimed salt from the mine outside in an ever increasing amount. Those willing to take the risk can steal from the outer perimeter of this deposit and gather a small fortune in salt which can be sold to the traders at Lingmell. This is the primary source of income for the young men of the horse people and adventuring bands in the region.
