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.

Ralia is one of the gem dragons. This group of dragons was the elite dragon from each species in Gaarafans Nin-clan. Ralia's gem is the emerald. But even if she is one of the gem dragons, she is the weakest. She always stays unnoticed and is weaker than the newly matured dragons who arnt mint. She also always stays at home, when the gem dragons fly out. Her dearest friend is Sakura, always tries to get Ralia to come along.
