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.

Knowing his parents it's no surprise that Rat turned out a rather bratty, rebellious  hatchling. He grew out of that a bit when maturing but not completely. He holds no respect for authority, challenges the establishment, and holds no regard for appropriate behaviour. He often strays far from the lands of the clan and travels the world visiting areas in which dragons live completely isolated from humans as well as areas where there are mostly humans and dragons are regarded as almost god-like creatures of mystery.

He was appalled when he visited the twin kingdoms of Night and Day where the humans gladly lived under the rule of dragon monarchs. He was about to give both of them a piece of his mind, starting with Astra the queen of Night, when his gaze fell upon Twili—Astra's daughter.

Ever since that day, rebellious Rat has thought of nothing but of a way to approach the sheltered princess and make her his mate.
