House Stark is one of the Great Houses of the Seven Kingdoms and the principal house of the North. Its seat is at Winterfell, one of the oldest castles in the Seven Kingdoms. Its coat of arms displays a grey direwolf running on a white field, and its words are Winter is Coming. House Stark had ruled as the Kings in the North for thousands of years until House Targaryen conquered Westeros, whereafter the Starks are the Lords of Winterfell and Wardens of the North. For prizing honor and devotion to duty, House Stark is the closest of the noble houses to heroism.
