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.

As Reve was the only egg so far to ever have gotten sick under Filari's care, many had been worried about her before she even hatched. Even when she has since grown up and is perfectly healthy, many a healing item or trinket has been snuck into her part of the cave. The Health Division has visited her quite a few times, but these visits she really doesn't mind since that group as a whole isn't too bad. They don't want another Mirnweld or string of deaths by a mystery killer, they say, not again. But they could afford to be less stifling about it and let a dragoness eat and sleep near a mana pool in peace!

Strange dreams enter her sleep with a very high frequency. All she seems to be getting so far are vague, abstract death scenes. In each one, she always sees herself presiding over it and getting the body ready. There, Reve seems to have an authoritarian purpose about her. She always describes the dreams to the Health and Magic Divisions, who have their own theories.
