During the Dance of the Dragons, House Dustin supported the claim of Rhaenyra Targaryen. Lord Roderick Dustin, known as Roddy the Ruin, led 2,000 northmen south of the Neck to aid the blacks.
The so-called grizzled Winter Wolves rode shaggy northern horses and used axes, mauls, spiked maces, and ancient iron swords. They led the attack and charged the Lannister spearmen five times in the Battle by the Lakeshore, with two thirds of the northmen killed or wounded in their victory. In the Butcher's Ball, Lord Dustin sounded the charge of the northmen and their river knight allies against Ser Criston Cole, the Kingmaker, who was slain in the subsequent battle.
Screaming northern war cries, the surviving Winter Wolves rode from a postern gate in the First Battle of Tumbleton. Although outnumbered ten to one, Roderick led the northmen to strike at Lord Ormund Hightower. Roddy the Ruin managed to slay Lord Ormund and Ser Bryndon Hightower before succumbing to his wounds.
