Direwolves

A direwolf is an unusually large and intelligent species of wolf. Direwolves are held to be mythical in most of the south of Westeros, although there are rumours of them living in the Wolfswood near Winterfell. The Night's Watch who guard the Wall and the wildlings who live beyond it both claim that direwolves can be found in greater numbers in the Haunted Forest to the north of the Wall.

The direwolf is the family symbol and crest of House Stark.
