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.

Sigyn was the first girl to grow up in this part of the cave, and she didn't have any sisters or female friends around her. Even so, or maybe therefore, she grew up to become a lovely lady. She is quite charming, and almost like a mother for all females that are sent to this part of the cave. If any of the males are rude, she knows how to make them apologize and behave.

After Sigyn's second child had hatched, her life changed. Her daugther ran away from home to become a wild dragon, and for some reason she didn't want to see her mother, nor her father, Urie Hulda.

Since that day, Sigyn became a more careful dragon, but still as kind as before. And she protects the young ones better now, because she somehow blames herself for what happened to her daugther.
