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.

Greenscale led an interesting life. He grew up in a very strict clan of dragons. Most clans believe in mating with similar or identical breeds as oneself, and Greenscale's clan was no different. His family arranged his mating with The Green Stone, and, although she was nice, Greenscale was unhappy.

Greenscale left his clan, venturing outside the small forest he had spent his life in, looking for new experiences and new dragons to meet.

He was in a relationship briefly with Ban Ketsa, but, once again, Greenscale was dissatisfied with being rooted to one place for too long, and he continued his exploration.

But, he eventually grew old, and tired of travel. He met Fircewind, and while they were breeds that were unusual to mate together, they are happy, and the head of the Cloudstreak family.
