The Grey Mountains are a large and high mountain chain located between Bretonnia and The Empire, belonging de facto to neither realm. Forming a natural buffer zone between the two countries, the Grey Mountains are a natural hideout for brigands, mutants, necromancers and tribes of Orcs and Goblins.
Beginning in the hilly Gisoreux Gap, which separate the Grey Mountains from the Pale Sisters, the mountains quickly rise in height in their way southwards converging in the Vaults.
The Grey Mountains have relatively poor mineral deposits and this lack of riches discourages a major Dwarf colonization. The local Dwarf settlements are few and, compared to other Dwarf strongholds, small and rustic. The local Grey Dwarfs, as they are called, are rather poor and simple in their tastes and likely to leave their homes in search of adventures and riches. The largest and most important Dwarf stronghold of the Grey Mountains is Karak Norn.
