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.

Frightful Dissonance is known mostly in his master's cave for his horrid shrieks, repulsive dietary habits and a body odor that causes even the neighboring cave's brimstone dragon to wrinkle its snout in disgust. This dragon does not seem to mind, however, and instead experiments in increasingly gross ways to have the prey it captures become "delicious"... including letting the prey's corpse rot upon the cave's disposal heap or place it strategically so that it stews in a small pool of blood from other prey (which are dealt with in ... interesting ways as well). For some unfathomable reason, Frightful Dissonance has a slight fancy towards the Lumina Dragon, Scayle. She however has begun taking great pains to avoid the pungent Black Marrow. Maybe she wouldn't be so opposed to him if he stopped bringing her his ,er, finest delicacies. Maybe it's the way he tries to sing to her instead....
