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.

This male makes his home along a pretty little trail, a path through the mountains that only a vicious tyrant and his soldiers know of. Oh, it's not that they're the only ones who have seen it, so much as they're the only ones who have lived to remember it. For the road through the mountains is a road to death; those prisoners who sufficiently annoy the mad king are set to walk down it, and in doing so soon encounter the resident Marrow dragon population, who give them a most gleeful welcome. But while this male appreciates the steady influx of food, the real reason he's in the area is quite different; there's a particularly lovely female Marrow there, one that he's most earnestly courting.
