Grey Mountains

The Grey Mountains are Mountains north of the Vales of Anduin, Mirkwood, and Wilderland, and they are south of the Forodwaith. This biome has spruce trees and mountains of stone. This biome was a kingdom of dwarves, long ago, but they were driven out. These Mountains, according to legend, are where the Dragons came from. The areas of the Grey Mountains that aren't mountains are large spruce forests. It snows here instead of raining, but snow does not accumulate beneath a certain height. Large boulders also make up the terrain. Orcs and Wargs of Mount Gundabad spawn here at night. No structures spawn.

Sub-biomes
The Grey Mountains have one sub-biome, the Grey Mountains Foothills. The foothills are less mountainous than the actual Grey Mountains. The Foothills only spawn on the south side of the Mountains; the Grey Mountains have direct borders with the Misty Mountains (west), the Forodwaith Mountains (north), and tundra (east).

Mobs
The only mobs here are the creatures of Gundabad, except when Dwarves of the Iron Hills invade the place.
 * Gundabad Orcs - Orcs allied only to themselves. They carry hammers, battleaxes, swords, spears, and daggers.
 * Gundabad Orc Archers - Gundabad Orcs with bows and arrows.
 * Gundabad Wargs - Wargs (giant wolves) allied with the Gundabad Orcs. They can be ridden by normal Orcs or Archers.

Vegetation
Any size of spruce trees spawn here and also some pockets of grass.
