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.

FearfulMarrow is a Black Marrow Dragon who has a lot of irrational fears. She's scared of spiders, rats, the dark, and Gold Dragons. She lives in the cleanest cave one could ever find, with a huge bonfire always going right in the middle. She doesn't get many rats or spiders, and every spot in her round cave is illuminated. But FearfulMarrow can't do anything to prevent her from running into Gold Dragons. There aren't too many Golds in her cave, since they are a rare breed, but she can't ever been certain where they will be at all times. No one is sure why FearfulMarrow is so scared of Gold Dragons, who are certainly not a very dangerous species. Even FearfulMarrow herself isn't sure why she fears them so much.
