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.

Ilvery is the founding mother of all the Frilled dragons in her Keeper's cave. She is vain and loves to show off her frills. At times, she can be quite a pest, parading around the cave with frills and wings proudly extended while other dragons are trying to sleep. At other times though, she seems to be grudgingly respectful and nice to the other dragons. Her favorite foods are large lizards and snakes.

Ilvery's mate is Ilamhe.
