House Dustin of Barrowton is a noble house from the north. Their castle is Barrow Hall in Barrowton and their arms portray two rusted longaxes with black shafts crossed, a black crown between their points, on yellow.
The Dustins claim descent from the First King of the First Men and the Barrow Kings of the barrowlands, which they honor with the inclusion of a rusted crown in their sigil.
House Dustin supported Rhaenys Targaryen in the Great Council of 101 AC at Harrenhal. Lord Roderick Dustin led two thousand northern soldiers, known as the Winter Wolves, during the Dance of the Dragons.
Lord Willam Dustin was one of the six companions that fought alongside Eddard Stark at the Tower of Joy. His bones were buried in Dorne.
