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.

Frellus intimidates many of the dragons in his cave when he first meets them, but over time the others just ignore his antics. When he isn't showing off his massive frills, he enjoys curling up beside the females to absorb some sunshine. Though he doesn't earn many ladies with his frills, he can protect hatchling with them by scaring away other predators that would try to do the little creatures any harm.
