Aria dragons are a brightly-colored and sprightly breed, perhaps most adored for their lyric calls. Their song-like melodies fill the areas they inhabit; their coos resemble those of birds, only more elegant and refined. They have fairly strong magical capabilities, but tend to reserve these strengths for last-minute defense, choosing to live their lives in simple peace. Arias, sticking to the tropics, typically live quite far from human settlements, giving rise to the previously held belief that they had gone extinct.

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.

Lule is a pacifist. Quiet and calm, she's hard to surprise and always wears a small smile. It's hard to know what Lule is really thinking, as her expression rarely changes, leaving one confused.

There is an odd sense of mystery surrounding Lule, and she is reluctant to open up and reveal her true self to others. Vatten Cavall is one of the few who she trusts, because he is open with her about his excessive levels of vanity.

The other dragons find it hard to dislike Lule, but also hard to actually like her; as she can be unapproachable due to her seeming lack of emotion, and intriguing coyness.
