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.

Her name means "Mere Skeleton" in Japanese. She is one of the many daughters of Kentaro and Kiyomi, and is her daddy's special little girl. Since her parents always stress cleanliness to their hatchlings, Keigai doesn't smell that bad. She cleans herself fastidiously after each meal, and tries not to eat anything too stinky. She still has a little bit of a natural musk, but it's not so bad. She's a calm and friendly dragon who loves to socialize with the other females. She also loves to make art out of the bones left over from her meals. She makes beautiful, if eerie, wind chimes that make the most haunting and beautiful sound. She met her mate Hagetaka, at a social gathering. He was off to the side because of musky odor, but Keigai didn't mind, she found it to be a masculine musk. They started courting soon after, and became mates on a beautiful winter day. They were made for each other, they're soul mates. They look forward to being together, forever.
