A Clash of Kings
Lord Steffon is seen berthed next to the Fury on Dragonstone by Ser Davos Seaworth. It is part of Stannis Baratheon's fleet commanded by Ser Imry Florent during the Battle of the Blackwater. It flanks Fury with Stag of the Sea in the first line of battle. During the battle, it manages to break through and make it upriver with the Ragged Jenna and the Swift Sword.
