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.

Young Leeroy is the third of MBlackwood's eggs to grow to full maturity, and, in many ways, he shows this "third sibling" status through his actions. Usually meek around his older siblings (at least, more meek than he is around most everyone and everything anyway), he seems to consent to whatever decision Protector and Medicus come to without question. Subject to an acute paranoia of any and all insects, the summer months are an absolute misery to Leeroy, for whom the flap of a dragonfly's wing is equivalent to the onset of the apocalypse.<br/>He seems to have actually warmed up to the Keeper a little, after seeing her around the nest for so long. As opposed to his typical habit of fleeing behind the nearest rock at the approach of anyone foreign, he will hover at the edge of the group, almost willing to come forward and greet her himself, but not quite brave enough yet. The Keeper is eager to get to know Leeroy better, and hopes that he will eventually overcome this fear.
