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.
Born and raised with her two siblings in Akeem's lair, Lunostra and her siblings were raised perfectly by the co-co leader Relli, but there were a lot of problems. Lunostra was a really girly dragon and not a very normal Black marrow. Her bones never came out of her skin as much as her siblings although she did have the sharpest beak of the 3 but she never used it properly. She really only used it to eat the marrow out of the bones and "attempt" to attract a mate.
