Frilled Dragons are smaller than most other breeds, but when threatened, they stretch out their wings and frills to appear larger. They generally do not like to fight and prefer hiding to confrontation. Frilled dragons live in small groups and often band together to scare off potential threats. Males also use their frills as a way to attract mates, with those displaying the “best” frills being more likely 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.

Jethro d'Orly is a goofball, even by his breed's standards. His disarming charm generally causes even the most irritable personalities to stop and laugh at his antics. He is fiercely proud of his frills, and takes care to keep them immaculately clean and in-shape, as they form the majority of his hunting strategy. When Jethro hunts he spreads his wings, which are decorated with hypnotic swirls, in order to paralyze his less intelligent prey.
