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.

Shimame is unusual in her liking for sweet things. Though mainly a vegetarian except in mating season, she has a fondness from sugar and other such treats. She is also quite loud, and is prone to shrieking loudly if she wants attention, or if she needs something, or if she's simply bored. Her favorite treat is mint, and whether it be a simple mint leaf or a pastry with mint flavoring, she will love the gift-giver forever should she receive such a treat. However, come breeding season, Shimame becomes rather unsociable, and only bribery will get her to cooperate unless she so chooses to.
