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.

As the daughter of Ghergo Yoaral, Vor Irsa was raised to disregard appearances and look at someone's heart. Not surprisingly, Vor Irsa fought her own bouts with bullying because of her appearance and habits, but she overcame them by making many good, loyal friends and sticking with them no matter what. Everyone was surprised when Vor Irsa fell in love with a golden wyvern, arguably one of the most handsome and high-born dragons around. Vor Irsa said she knew that he was lonely, because his kind was not easy to come by, and that his special abilities made him an outcast in his own right. Vor Irsa claimed him as her life-mate, and the two of them found a high mountain peak to call home, giving out advice and assistance to all who needed it.
