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.

Slender Man prefers to lurk in wooded areas, especially around rivers. This dragon cares nothing for interactions with other dragons and has no desire for a mate. Some dragons, when they get enough courage to speak of Slender Man aloud, agree he must have no true emotions. Slender Man seems to enjoy only one thing: scaring humans. Once you look upon Slender Man, he knows you. He only preys on a single human at a time, and will spend months slowly cultivating the terror and fear of his victim. He begins as nothing more than a shadow as you fall asleep, a tiny noise that is easily dismissed, and little by little -- bit by bit -- drives his victim to the brink of sanity.
