A machine of war, constructed and assembled in the general form of a defender of the Imperium, threaded through with the necessary flesh and viscera of one initiated into the mysteries of the Omnissiah. An ascetic slaughterer born of the Astartes, mentally sculpted and physically augmented into the likeness of Dorn, honed and guided to become a necessary tool in maintaining the war against the Emperor's foes.
One may see aspects of either, or both, when observing Brother Sterngraf, and maybe even consider that some of the flesh one sees was a child, once. If Sterngraf recalls anything of such times, he does not share.
Unflinching in the face of direct opposition, calm in the face of goading, resolute before charms, and unforgiving of intimidation, Sterngraf has memorised Dorn's address to the three hundred magistrates of Terra, and makes no effort to stand for kindness or hope within the Imperium - only piety and faith in Primarch & Emperor.

Brother Sterngraf wears tactical dreadnought armour. Thick with ceramite-coated plates and molecular bonding studs, the suit is covered with reliquary inlays and inscribed scriptures of damnation. The suit is considered overly temperamental, even ill omened by the artisans that must work on it. In battle however, it almost seems to predict the bearer's movements, efficiently moving from kill to kill - equally at home amidst a flurry of blades or the ring of spent bolter shells.

Armed primarily with a well maintained cyclone missile launcher, Sterngraf relies on brother marines to pick out concealed targets beyond augur range, drilling through all but the toughest of multi-layered cover. Protruding from his armour are four heavy lifting servo arms, plus two retractable tool arms for delicate work. Though the servo arms mount the majority of the harness' weaponry (in the form of matching power blades and two guardian bolt pistols), the tool arms also hold a fyceline torch and plasma cutter. Capable tools, but equally deft when used as instruments of destruction.
