Falconiform Wyverns are normally shy creatures. However, when approached, they often feel threatened, and the flames along their bodies leap higher. Females tend to be smaller than males, though Falconiform Wyverns are typically rather large overall. They use their size to their advantage by hunting smaller dragons. The Falconiform’s graceful, swooping dives are said to resemble birds of prey. Falconiforms are largely solitary dragons that only meet in order to breed.

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.

Ubb is called "Bub" by her parents and siblings. She resides in the human populated town of Arbeit, outside the business district, and is known as Ubb to denizens. She doesn't remember how the B moved to the back. People there are, at most, slightly wary of her, but she's assured them that she's staying far away from any flammable building or landmark and won't eat humans because they're too small and bony. She can live in the lot with the old tenement building beside it and do whatever she likes to the property due to the business and outdoor time she indirectly promotes. Since she arrived at Arbeit, many of the scarier, meaner creatures that used to come to town have stopped, even the nasty jellements that once flew freely along thoroughfares, spraying hot paste. People assume the dragon presence keeps them out, even though she's probably more scared of any of them than they are of her.
