House Ironmaker is a house of the Iron Islands whose neither arms nor words are recorded. Its elderly head, Erik Ironmaker, claims to have sailed with Lord Dagon Greyjoy in his youth, and puts himself forward at the kingsmoot on Old Wyk with his grandsons standing as champions and gifts of silver, bronze, and steel; his claim collapses when Asha Greyjoy demands he stand and he proves too feeble to do so, and he is later seen shouting his support for Euron Greyjoy instead.
Euron rewards that support: he weds his niece Asha to the aged Erik by proxy, a seal standing in her place at the ceremony since she has already fled Old Wyk, and names Erik Lord Steward of the Iron Islands and castellan of Pyke to rule in his stead while he wages war for the Iron Throne.
