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.

With a rare dark-colored Sweetling as his sire, this male's inherited a very unusual set of dietary preferences. Snapping up fruits and blocks of sugar as readily as he does meat and bone, his eating habits have earned him no small amount of teasing from the other Marrows--although he can generally shut them up with a few good blasts of fire to the face. When not grumbling to himself or asserting his status as the biggest, meanest, ugliest Marrow around, he's been known to very shyly leave dead roses at the entrance to a certain female Marrow's den, always fleeing well before she can spot him.
