Fell Dragons are a primitive, fractious breed. They are born small but grow astonishingly quickly throughout their adolescence, and constant hunger inspires them to eat nearly anything that can be made to fit into their mouths. Legend has it that they never completely stop growing at all. Adult Fell Dragons are massive juggernauts: a diet rich in minerals and metals harvested from the earth helps them grow a dense, scaly carapace along their backs and toughens their thick hides, while their wickedly sharp claws and the bony, ax-like crest on their heads are well-suited for both hunting and physical combat. Though few Fell Dragons have crossed paths in the wild due to their primarily solitary nature, it is said that their thunderous disputes can be heard—and felt—for miles around.

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.

True to her name, Rottweiler is rowdy and rapacious. She communicates exclusively through loud roars and roughhousing. Nothing gives Rottweiler more satisfaction than a good fight, especially against opponents that can match her size and strength. Her primary opponent is her father, Hell Hound, whom she has never been able to beat even once. She'll also frequently go head-to-head with many of the Royal Crimsons and Galvanics in her family, who all seem to either love or hate her for this behavior. Rottweiler doesn't seem to care or notice either way, so long as she gets a fight. While she may be reckless and simple-minded, Rottweiler is extremely protective of her close family, especially those that indulge her fighting spirit. She's especially close with her mother, the Ember, Blasting, who is much, much smaller and more delicate than she is. In fact, Rottweiler has a tendency to defend smaller, arguably weaker dragons. She'll even carry them around on her back or in her jaws.
