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.

Fiona is a very sweet tempered and gentle dragon. She loves speaking with friends and refuses to harm another living creature, coming close to tears whenever she thinks of how much others fight. She can't stand Raven, Ambient, Specula, Kanan, XasTareth, or Bloodlily because of how violent they are, and will go far out of her way to avoid them, if possible.

She is an innocent, and extremely gullible because of it. Yet at times, she seems to be ancient beyond her years, despite her usually childish behavior. Sometimes, she appears to be able to gaze into the future, though it's impossible to understand her (usually grim) predictions. Perhaps the surprising maturity that she exhibits on occasion comes from her ability to peer into the future She usually faints right after having one of these "visions", however, and then forgets she ever had one upon waking.
