Hammers of Dorn

The Hammers of Dorn is a Codex Astartes-compliant Space Marine Chapter raised from the gene-seed of Rogal Dorn as a Successor Chapter of the Imperial Fists during an unknown Founding, but which dates back no further than the 41st Millennium. The Hammers of Dorn are stringent adherents of the Codex, and uphold Guilliman’s scriptures with exacting precision. This has fostered a great rivalry with the Ultramarines and their Successor Chapters.
