Pale Sisters

The Pale Sisters form a northern extension of the Grey Mountains, between which lies the Gisoreux gap, the confluence of all the overland trade routes between the Empire to the east and 1a Bretonnia and the Estalian Kingdoms to the west and south. The mountains are largely barren, inhabited only by brigands and a small number of goblins. Some of the peaks are said to resemble bent old crones, whilst the eternal snow covering gives them shawls, hence the name of Pale Sisters.
