Orcs of the Misty Mountains

The Orcs of the Misty Mountains were tribes of Orcs settled in the tunnels in or under the mountains. They served Sauron since early on, guarding the passes and troubling the folk of Eriador . These Orcs were also responsible for the death of Isildur and the loss of the One Ring . Later on, though they harassed the peoples and regions around them on their own for a time, their bond to Sauron remained strong and even though he commanded from the far main dominions of Dol Guldur and Mordor they still carried out his will, occupying Moria and barring the paths through the mountains.
