Warg

The warg is a large, aggressive breed of wolf often used as a mount.

They are found in a number of varieties throughout Norrath. The larger and more aggressive varieties are classified as dire wargs. They are found in a variety of colors, most commonly black, brown, and gray, though orange, red, and even pink varieties can be observed. Warg fur patterns are generally solid, striped, spotted, or two-Tone. Other specimens include the ghostly, ghostly dark, enchanted, Mistrunner, and Nightmare varieties.

The seniormost male of a pack of wargs is regarded as the alpha.

A warg that is wearing armor is referred to as reinforced.

Among the more renowned trainers of these ferocious beast is Wolfmaster Heinrich from Somborn Village in Loping Plains, Faydwer.
