Royal Blue dragons are a nocturnal breed who prefer to live high in the mountains near slow-moving water that reflects the night sky. Although quite capable of defending themselves, they are peaceful by nature and will avoid a fight whenever possible.

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.

Trees roams the woods and forest on the clan's lands at night. He loves the peaceful serenity a dragon can find among the giant firs and oaks, watching the moon's reflection in one of the many small ponds. This dragon has a secret joy he shares with nobody. At one of the ponds he regularly watches a unicorn, who comes there every night to drink from the cool, soothing water. Trees still wonders if it would be a good idea to approach her, but he hasn't made up his mind yet.
