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.

Sally Eskelless is a Black Marrow female and the mate of the 'Pumpkin King'. Though she shares her mate's bony appearance she is as true and loyal a mate as any dragon could wish for.... and, like her mate, she can sing! Though among the Halloween dragons of the JavaTiger, the two are held up as an example of true love, it wasn't always so. It is said that she crushed on him without his ever noticing... mostly due to his distraction with other matters...for many a long day before she happened to catch his attention. How, exactly, this came about depends on the version of the story one believes. The most common versions of this story say that Jack had gotten himself into trouble with investigating other holidays which he didn't completely understand. It was with HER help that he came to realize that sometimes what you are missing is right in front of you. These days, of course, she chiefly helps Jack with leading the Halloween dragons in their preparations for the 'festival of fear'.
