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.

Jagquari hates when she has a bone to pick. When splitting the last of some remains with her flockmates, she often sits over the skeleton, muttering, "eenie meenie miney moe..."

Then the neotropical generally known as "eeeny" shows up thinking she has been called. Where one banana goes, others are soon to follow, and half the time the marrows get forced off of the carcass by sheer chicanery. Jagquari takes herself very seriously and is horribly embarrassed by the angry looks she receives after inciting such an incident. She tries to make decisions quietly in her head, but after a while she starts mumbling again. Some have suggested she roll a die, but dice tend to be carved out of bone, which means they are so crunchy to snack on that she can never keep enough on hand when she needs to roll one.
