A Dirus is a breed of wolf native to northern Andoras, particularly Frostfall, and a region of Doras Edrossi known as Tegrush. They are known to be larger and stronger than the average wolf. Their size has been reported to range from 3 ft to even 5 ft in height and tend to weigh at an average of 70 kg (154 lbs.) and 100 kg (220 lbs.). House Stenwulf took the Dirus as their sigil.
Legends and visual accounts of travelers in Frostfall speak of a Dirus who roams the farthest reaches of the north in Andoras, whom is apparently notorious for his larger than average size. He was nicknamed Snowhide, due to his immaculate white coat, which is coveted by many a fur trader and skinner.
