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.

Stars is utterly in love with Nebula dragons. She thinks there are no other dragons who can match their glorious beauty in existence, and she couldn't care less what Silver dragons or Luminas say to the matter. But while she's absolutely fanatic about her personal "type", she also has so little confidence that she could never find the courage to approach one of those celestial individuals. So she stays with her mate instead, a handsome enough fellow who has enough confidence not to be bothered by her excited reaction every time they meet one of their Nebula clan mates.
