The Grey Mountains is the mountain range forming the border between the Empire to the east and Bretonnia and the Forest of Loren to the west. It stretches out from the Vaults in the south to the Pale Sisters in the north close to the Sea of Claws. One pass bridges it, the Axe Bite Pass which is guarded by the many fortresses chiefly that of Montfort and ends close to the city of Parravon at the Bretonnian side while at the side of the Empire it is flanked by the city Helmgart in Reikland.
The Grey Mountains accomodate scattered communities of Dwarfs but they are neither numerous nor wealthy. The largest hold is Karak Norn which lies east of the Forest of Loren. Within the mountains also lies the Mound of Krell.
