After the 13th black crusade the iron wolves were renamed to the duskwolves after torval wyrdbane was chosen to become the next jarl, however in the latest novel krakenblood there is still a pack of iron wolves, now i currently havent read the book so i dont know if its set before the siege of fenris/black crusade but is It still possible some marines still choose to potray their old Heraldry instead of the current One?
