Dusktown Cavern is the southernmost cavern of Blackreach: Greymoor Caverns where the Bitterblade Mining Consortium has recently begun operations. The walls, ceilings, and floors are all covered with giant purple geodes that illuminate the majority of the cavern. It can be reached via Silversnow Mine.
Though the smallest beneath Western Skyrim, Dusktown Cavern is the only system to connect directly to all other Greymoor Caverns. There are passages to Dark Moon Grotto to the west, the Lightless Hollow to the east, and Greymoor Cavern to the north. The secret mining village of Dusktown is found in the western portion, while the eastern area is occupied primarily by the Falmer of Gloomstalker Village. The Dwarven city of Nchuthnkarst can be found in the northeastern branch of Dusktown Cavern.
