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.

Mario sergio was in the past selfish, egoistic, superficial, childish and a show off. It was since he discovered that his species had almost gone extinct and that frilled dragons can't produce their own kind anymore that he turned into a complete different dragon. He became a more serious, mature, kind, warm, honest, funny,  protective and most of all appreciative of the things around him. He feels that he can't waste another minute of life living it selfishly because it can be gone in a second. He feels he could have done more for his kind to help. Dragons in the clan that knew him before he changed don't believe him and he has a hard time proving himself to them. He is persistent and longs for recognition. He teaches young hatchlings how to communicate with each other and how to work together as a group.
