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.

The Bone Thief roams the arid, flat plains of the southwest, between the harsh desert and marshy bogs. This sparse, barren territory belongs to the dragons of the Fallen Weyr. The dragons of this Weyr are war-scarred elders, scrawny young adults with empty bellies and hungry eyes. There is little upon which they agree.

Except that the Bone Thief is to be feared. Avoided.

Fled.

The Bone Thief follows in the tracks of the Fallen Weyr as they rove the wastelands, sneaking closer until the dragons whisper warnings of him. That his leathery hide clings tight, skeletal to his form. That his crown of bones has braided into a single long, thin blade, sharp enough to pierce a dragon's breast, kill them before they even feel the pain. Any cracking sound on the wind could be his beak snapping bones, eating the marrow of his latest scavenged find.

He is active in autumn, seeking meaty bones sweet with marrow and rot. Stealing them when he must. No matter the dragon to whom the bones once belonged.
