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.

Lady Hydrangea is named after her favorite flower. She's a peaceful dragon and enjoys caring for various plants outside the cave. The habits of other dragons repulse her and she prefers to spend her time alone in the wilds. Animals can sense her compassionate nature and do not flee from her. Luckily for them, she is herbivorous. If a bird happens to land upon her back, she is careful not to disturb it. She loves the songs of the birds and will stop what ever she is doing in order to listen. If they sing to her long enough, she may be lulled to sleep.
