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.

Scylla dug into magics that she should not have touched when she was a hatchling and accidentally froze her Black Marrow playmate Mekor in a permanent state of immaturity. Having learned her lesson, she turned her back on magic forever. Guilt drives her to protect Mekor as fiercely as though he were her own son, and over time he has come to view her as his dam. She avoids Grenar, their other former playmate, sensing disapproval in his red eyed glares, but has come to be friends with Arakkis who has done his best to help her to understand that while she made a mistake, it's not something to cling to as a life-long shame. Perhaps one day she will take the Magi Dragon's words to heart.
