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.

Uricoria is slightly jealous of her mother, Yagissa, because of her beauty and how much attention she attracts. Her father, Arnaar, always tries to convince her that she's just as attractive and that she wouldn't have had any mates otherwise. While it's comforting knowing that her father has her back, there's still a part of her that just won't let go of the jealousy.

Uricoria likes to study constellations. She is often seen lying around on her cliff to find any patterns in the stars, whether the constellations are real or not. While she prefers her solitude, sometimes she likes to have some company to share her hobby. Her father stops by once or twice a month to stargaze with her, often in silence, hardly ever saying a word to her and vise versa. Even when she doesn't particularly feel like having company, Uricoria does appreciate her father's consideration when he does stop by.
