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.

Rooreth is the eldest dragon in Zephyra's clan. She was the first dragon raised by Zephyra, and was the only dragon from her clutch to survive. When she matured, she realized how hard it had been for Zephyra to raise her on her own, and vowed to help Zephyra raise any new eggs that came into the cave, no matter what breed or who the parents were. If it were not for her, Zephyra probably would not have been able to raise the dragons that she has. Due to her involvement in the raising of almost every dragon in the clan, Rooreth is affectionately known as "Grandma" by the other dragons.

Rooreth's mate is Sylexion Maru, the clan alpha and elder, and she loves him and their son Peroth more than life itself.
