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.

When she was growing up, Ghergo Yoaral was ostracized and scorned because of her appearance and strange eating habits. The other hatchlings would taunt her because she wasn't cute, or pick on her for the way she would "prepare" her food. Ghergo didn't understand why she was different, or why the other hatchlings hated her, but she knew one thing; she didn't like being made fun of. She tried simply ignoring their taunts, but they didn't let up. Finally, Ghergo had had enough. She ran away from home, heading deep into the forests where no other hatchling dared to go. She hadn't gone far when a Guardian of Nature showed up and asked her why she had entered the forest. Ghergo Yoaral explained her situation, and the Guardian told her that it didn't matter what the other hatchlings thought, that Ghergo was special and unique just the way she was. Ghergo realized that the Guardian was right, and vowed to help others being made fun of for being different. That has been her mission ever since.
