Blue-Banded Dragons are found primarily in mountainous regions with lots of precipitation. Although terrestrial, they are most often sighted near running water and feed mostly on fish. Females are very social and form tight-knit family groups, while males are strictly solitary and will fight any other dragons that enter their territory outside of breeding season. For this reason, females tend to drive males away when they are not ready to mate, or when they are caring for hatchlings. The amount of striping varies greatly from individual to individual, with some dragons having only faint dark streaks on their sides and others appearing to be almost entirely dark blue with paler markings.

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.

When Overeating was growing up, his adoptive family lived in a system of caves, treehouses, and wood-and-brick houses where denizens have nearly perfected all processes related to basic resource gathering, so food and other always-needed items were plentiful. His parents and aunt were skilled at catching food in the traditional manner as well as doing work to get food, so as a youngster, he ate well. Once he was grown, he left the bustling and complicated community for a refreshing solitary existence. A lot of skills he learned when he was little are no longer useful when he's on his own, so he's forgetting things and learning new things every day. It's a lot harder getting food when one can't just go down to the fishery or to the store, so overeating is not really something Overeating does any more.
