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.

Lanius loves his mate, Valx, and will happily support her in everything that she does. However every time he sees her talk to someone he doesn't like, laugh a bit more heartily at somebody else's joke, or even spend more time with someone other than him, he feels jealously well up inside. He loves her, of that he is sure, and she is the first dragon he will seek out when looking for company. Yet every time that he is not her first choice, he feels rejected and lonely, and skulks around in the corners, knowing that he has nobody else to talk too. The anger that he feels inside when she talks to someone else scares him, and he ranges between hating himself for being this way and hating her for making him feel like this. Lanius has made efforts to try and talk to more people, but always leaves their company feeling embarrassed and stressed. He knows he needs to get over his obsession with Valx, for both of their sakes, but he wonders if he will ever manage to succeed.
