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.

Utaoji can be a bit of a spoiled prince in demeanor at times. He claims that because his hearing is so sensitive, listening to unpleasant sounds causes him massive amounts of stress. He prefers the company of the tropical birds with the prettiest voices, and will sometimes turn down party invitations with ill-concealed distaste if he hears that music will be provided. Incidentally, he still wonders why he doesn't get invited to festivals more often.
