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.

Vassago is a vicious and downright unpleasant creature. He is usually paired off with his Kohraki partner, Gusion, since the both of them share a distinct taste for flesh. They are notorious tricksters known to toy with their prey and even threaten the members of their own group. However, those who know them also know that they are both phenomenally stupid and a non-threat to anyone possessing strong enough magic. Vassago is definitely the smarter of the two, but he's also the most stubborn and loud-mouthed. He enjoys scaring others, almost more than devouring them. He'll always try to act sneaky and threatening, lurking in the shadows and making creepy noises to unsettle his victim before ambushing them. For as juvenile as he may be, Vassago does have a strange sense of loyalty to those that prove they can command him, or share in his distinct tastes (as is the case with Gusion.) He responds best to action and shows of strength. Simply telling him off has no real effect.
