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.

Frilledhearts mostly spends her time in Shadowheart's cave, or if the weather is rainy, then she would fly off somewhere and come back to the cave with one or two of Shadowheart's favorite gemstones. Being Shadowedheart's mate, she is the alpha-female of his clan and no other male dragon can touch her. She mostly protects the nest from ones who try to steal the eggs if Guardianshield is away. But that rarley happens.
