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.

Smashed Marrow likes to smash things up. She loves hanging around the clan's vampires, and smashing the eggs that do not turn into vampires... she's a real freak. Maybe that's why she has it so hard to find a male to mate with her—she's refused often. Seriously often. It may seem a miracle that she actually had children at all. And it was even more of a miracle that she did not smash her eggs, and they managed to become adults. All the other dragons were seriously surprised when the bets they had placed on her smashing her eggs before they were born actually failed. Nobody knows what's inside this horrid dragon's brain, but everyone knows she feels happy, since she won the bet against 300 dragons, and eats for free 300 days a year!
