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.
Mio was Shadow's eleventh dragon. She is a pink dragon, whose name comes from a combination of the Japanese word for beautiful, combined with the word for cherry blossom. Mio's mate is Shyama, a black dragon.
