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.

Eater is not his real name; his real name is unknown, for he disposed of it when he joined the Clan of Darkness. Apathetic and lazy, he joined the clan mostly out of convenience, for he'd thought that it would be easier for him to get food that way. Instead, he found himself steadily drawn into the teachings of Khymal, eventually finding himself completely under the sway of the clan leader's confident words. Now, Eater is a productive individual, something he finds odd at times.

Like all others in the clan, Eater was given his name only after being with the clan for some time and showing his true self and personality. His gluttony lent itself easily to the nickname of "Eater"; this nickname stuck and eventually became his clan name. Though now he is less gluttonous, he is still quite capable of putting aside large quantities of food in one sitting. His previous indolent lifestyle gives him a perspective unique to the clan, something that Khymal values; his clan-kin, not so much.
