Iron Snakes

The Iron Snakes are a Second Founding Successor Chapter of the Ultramarines. Their founder was Saur Damocles, Captain of the Legion's 6th Company during the Horus Heresy. The current Chapter Master, Seydon, is the eighteenth to bear that title since the foundation of the Chapter. Their primary mission is the safeguarding of the area of Imperial space referred to as the Reef Stars, although they are also known to have contributed forces to wider conflicts, such as the Sabbat Worlds Crusade and the Imperial response to the 13th Black Crusade.
