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.

Nitunadsila is the first child of Adsila (hence her name, which roughly means "daughter of Adsila") and Jethane.  While her mother's love was given to a strong black dragon, Nitunadsila's heart was stolen by a water dragon, Orastrilis.  They met when she perched on a cliff overlooking the bay where he lives.  Now she basks on the shore or flies overhead as he swims, and dines on fish with him rather than meat.  They have several offspring together, and like her parents, she has mated for life.
