Black Marrows are named for their dark colored hides which are encased in a distinct exoskeleton. Their skull and the top edges of their spine push out from under the skin as they age. As such, their young need excessive amounts of calcium for this armor to develop. The older a Black Marrow dragon is, the more skeletal their appearance. They often use their skeletal looks to lure in foolish scavengers or terrify predators. These vicious dragons love nothing more than to crack open bones with their stony beaks and eat the marrow inside. Voracious scavengers, Black Marrows will swarm and devour corpses both old and fresh, sometimes even dragging larger finds to the water to allow them to “ripen.” Despite their dreadful demeanour and often horrid stench, Black Marrows are devoted mates and parents.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

This dragon believes he's a descendant of a king from ancient times, who was turned into a dragon by a powerful wizard due to his tremendous greed. Hence he claims to be of noble birth; he has forgotten his original name and forces everyone he comes by to bow to him, since he is a mighty duke, and he deserves to be respected accordingly. Everyone he comes by actually do lower their heads and stay a certain distance from him—but it's not because of his birth -  it's because his breath stinks. It smells so horribly that some rumour his breath is lethal, so they have nicknamed him the Deathly Duke. And him, in a mix of ignorance and selfishness, has accepted it happily. Oh, ignorance is bliss.
