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.

Adagio Songbird has a musical gift, like most Aria Dragons. A confident and cheerful dragon, Adagio isn't afraid to share her passion of music to other dragons. Despite her talents, she isn't a narcissistic and boastful type of dragon. In fact, Adagio is very charitable and kind-hearted. She works as a "dragon sitter" in her free time, offering to look after eggs and young hatchlings. She especially enjoys quietly singing to eggs or hatchlings whenever they are afraid.
