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.

Many a child are told the story of Bone, a dragon who fancies the bones of children. Parents sit by the bed of their child, candle flickering and shaking like a leaf in the cold autumn wind. "There is a dragon so fierce, so evil," they say, as the child draws their blanket closer "that she only devours children. Those who stay out late at night often meet their end by her terrible teeth. Every Hallows Eve, she stalks this town and many more hoping to snatch young away. If you are wise, dear child, you will return tomorrow by midnight, before her prowling begins".
