The White Mountains is a mountain range within the middle of Aeramis. Though none of the mountains in this range are particularly tall, their location interferes with rain patterns near the South-East, creating the Yezeth Desert. The White Valley cuts through the mountains, creating the only walkable path between the western and eastern parts of the continent besides the two bridges near XXXXX. Shyvana makes her home at the peak of Dragon's Roost, part of this range.
The White Mountains are so called not because they are white, but because their relatively light gray color is in stark constrast to the Ashen Rock Mountains.
