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.

Keila was found in a cave and in a batch of four eggs, all of which were pink. As she got older, she was cared for every day and started breathing fire just a week after she was born. She's gentle and doesn't like to use her fire except in mating season when she eats meat. Other than that, she's a vegetarian who is very caring for others.<br/>Her first mate was Zao-Long but their relationship didn't go far after she had her first batch of eggs. However, she and Zao-Long are still very good friends.
