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.

Fell Apart destroys a lot of things, usually by accident due to her size. She feels bad about wasting those she can't eat, so she puts them to use as art materials. Whenever enough dead or knocked-over items accrue in her territory, she sticks it together in shapes that represent her feelings or interests at the time. She's even had a few shows to exhibit pieces she's particularly proud of. Oftentimes, other creatures make nests out of Fell Apart's artwork, or eat pieces of them, or pull them apart for any reason. She used to become angry about this but soon decided that it's a good thing that others are further making use of the things she originally didn't want.
