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.

Surrounded by beautiful, talented dragons from an early age has led Dia to see herself as useless, endlessly staring at her reflection in puddles as she despaired over her future. Concealing herself, she would watch the surrounding dragons, trying to figure out where all they obtained their skills and looks. After observing them for a while she came to the conclusion that she was, in fact, much smarter than the 'dim-witted butterflies' who flitted around the cave, what she once saw as an amazing skill turning into a simple party trick. Taking confidence from this, she began to manipulate those around her, turning simple dislikes into feuds, friendships into dust, so that it seemed as if mayhem walked in her shadow. It was when she tried to manipulate a young ember dragon, only to find the attempt crash in on her, she knew she'd found her true love. At first, she suggested they should just be allies, but as time went on he began to reciprocate those feelings, as they fell in love.
