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.

Skeletal Frame is part of a group of Black Marrow dragons whose main feeding strategy is to follow warring dragons around so they can clean up after the battles. She is among the friendlier members of the group, and is something of a chatterbox.

Her job within the group is to carry leftover meat from the battle sites when they leave, so they will still have food while traveling. Her mate, Corpse King, cuts the bodies into manageable pieces, which she carries in an old fishing net she found at some point. When not in use, she keeps this net draped around her shoulders where she can keep track of it.
