Mint colored dragons are the most peaceful of all dragons; they only eat plants unless they scavenge meat from an already dead animal. They also have no ways to attack others or defend themselves. They are much smaller than other forms of dragons since they only double in size when they mature. Mint dragons are unable to use magic and cannot fly since they lack wings. Their looks have given rise to the common insult of calling dragons “large lizards.”

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.

Flight, a girl who lives in the Mountains of Elgar and never ventures out to visit her own kind, was raising two other hatchlings when she was gifted with Hylio's egg. The mint-colored egg had been found abandoned near one of the streams that leads from the Lake of Elgar out of the Mountains of Elgar. Flight raised the egg while the finder, a Whiptail named Antiphons, kept a protective eye over Hylio as a hatchling. Alongside her clutchmates, Hylio grew into a bright, social little dragon. Despite being one of the smallest dragons in the Mountains of Elgar, second only to the Pygmies, Hylio never lets her size get in the way of her having a good time. One of her favorite past times is exploring the Mountains of Elgar. Though home of many dragons as well as Flight and one other human, Ember Nuria, the large region of mountains that stretches alongside the coast of the Western sea has never been fully explored. When not exploring Hylio lives with her sister Honna in the forest of Torhutyr.
