They are a frequent danger for travelers on the Eastern Road, crossing over the mountains into the Vale. They are frequently found in wild mountainous areas, with particularly large populations of shadowcats in the inaccessible areas of the Mountains of the Moon in the Vale of Arryn. However, they are not limited to the lands of the North above the Neck. Shadowcats are found in northern Westeros, with larger populations in the lightly inhabited forests of the lands beyond the Wall.
