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.

Bloodstrath is an incredibly fierce, young male. He is probably one of the most dominant dragons that have passed through his owner's hands and certainly the mightiest. Because of his troublesome nature he had quite some difficulties growing up to the dragon he is today, being isolated by the other hatchlings and later on excluded by the groups of the young adults. The only dragon that seemed to enjoy his company and didn't mind his antisocial behavior was a lively moonstone dragoness named Shihaasar. He immediately became incredibly fond of her  but due to her nocturnal nature the two got to spend very little time together even as they where young. Bloodstrath seemed to be quite distressed at the time because of this and decided to take matter into his own claws. Quite remarkably this Black Marrow changed his entire sleeping habit in order to be by the side of his friend which, as everyone has probably already guessed, became his mate later on as well.
