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.

Arethusa is a very shy dragon. She enjoys living in a dark, vine-filled forest and snacking on berries and greenery that grows there. While it's likely that she has a cave to call her own somewhere in there, no one has ever seen it. Arethusa will only come to the edge of the forest for Wystie, and even then she's easy to scare off. She is scared of most other dragons, but her mate Chrys is exceedingly gentle and patient. It took him many years to court her, but he eventually succeeded.
