Wargs (The Hobbit)
Wargs were a breed of wolves who lived in the Misty Mountains. Some were captured and used by Orcs of Isengard and Mordor in the Third Age, and others had an allegiance with the northern Orcs of the mountains. They appear first in The Hobbit, attacking Thorin and Company as they traveled east from the Misty Mountains.
In Théoden's retreat to Helm's Deep from the threat of Isengard in TA 3019, a scout reported that "wolf-riders" were abroad in the valley, but Wargs were not specifically mentioned.read more
