History of the House Wull Game of Thrones Lore

House Wull is the formal name given to the Wulls, the most powerful of the mountain clans from the north. The Wulls inhabit the area west of the northern mountains along the Bay of Ice. The chief of the clan is known as "the Wull", although at Winterfell he is given the treatment of "Lord Wull".
They blazon their banners with three wooden buckets, brown on blue, with a border of grey and white checks.

History
