- The location of the entrance to the Dwarven city of Nchu Duabthar has long been known, but so far its gates have defied all attempts, physical or magical, to open them.
Nchu Duabthar Threshold is a remote valley in the center of Bangkorai visited during the Daggerfall Covenant quest The Parley. The gates to the nearby Dwemer ruins have defied all attempts to open them.
The valley is considered neutral territory between the Imperials and the Daggerfall Covenant, and is the location of a meeting between Magus-General Septima Tharn and Queen Arzhela of Evermore. It is only accessible during the related quest, and cannot be reached from the main Bangkorai area.
