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.

Frilled was born to the "Frilled Prince" and an unnamed mother. He barely knew his mother, and has an especially strong dislike for his father. The Frilled Prince has had a multitude of children of different races. Although Frilled has the impression that his father truly cared for one "Lady Flora", the rest of his children are results of mistresses. Frilled's mother was actually in love with a dragon named Phoeniz Fire. Unfortunately, as a lower member of society, her feelings were not returned. Whether she conceived Frilled in an attempt to make Fire jealous or it was just business, Frilled does not know.

Frilled was born with an unusual sense of honor that none of his family possessed. He chose Mint the I on the account of her loving family. She was also very kind which he appreciated. They have children, who, despite their titles will not inherit the family line. Unlike his wife, this didn't bother Frilled too much.
