The Sons of Iron Chapter is a 26th Founding Successor Chapter of the Iron Hands. Hailing from the perilous world of Suami, the Sons have begun to gain a reputation, among the kin of Ferrus Manus, as an effective Chapter, whose sole and yet infamous stain is their beliefs tantamount to heresy in the eyes of the Iron Hands and many of their successors, while the Imperium at large consider them as a cold and unforgiving gathering of devoted Space Marines, exemplifying the better traits from their Progenitor without the strained relationships which are often the lot of Ferrus Manus lineage. Like all those who bear the Seed of Manus, the feel the drive to replace their flesh with bionics, but try to resist it, a strain which add to their already grim demeanour.
