Calh-Nhad is a village in the Haribos mountain range.
It has one accessible room, just inside the gates. SMOC Dihbl is here, selling button badges. His beaver coat appears to be unique in game.
To find it, from directly south of the Lower Djel Trading Post (on the road), journey west twice then walk west five times. Then journey southwest. When you hit the mountains, climb west until you see the lake and forest surrounding Calh-Nhad on the map to your north.
There is a convenient log bench in the terrains just outside the village.
