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.

Emerald Mystery uses his small size to try to sneak soundlessly through the forest and hide in the undergrowth. He hopes that he will develop skills that will cause the military leaders Obsidian and Crimson Flame to see him as a potential addition to the cave's defenses. He is still unsure in what capacity, but his goal is to one day be an important part of the cave's military force.
