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.

Since Huko does not have a close relationship with his father, he strongly takes after his mother, being a caring and kind dragon. He spends most of his time with the hatchlings, singing songs with them and creating numerous games for them. He wishes that his father would spend more time with the clan and Huko has discussed his feelings with his mother. But she encourages him to enjoy the family that he has in the clan, such as his half-sister, Kerzi, and her children. Still, the desire for a father lingers in his heart.
