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.

Callista is a dragon that seems to radiate a soothing aura of peace and relaxation. It sometimes feels as if her very presence is enough to resolve any uneasiness or calm any argument. She is every bit a leader as Antares, her mate, but in a different sort of way. Many of the younger dragons see her as more approachable than the intimidating Antares, and often go to her for advice or to give their input. Antares himself nearly always consults her before making decisions, as he trusts her more than anyone else. Additionally, Callista is a very good listener, and she genuinely cares about everyone's opinions. However, she is no doormat, and the others know better than to disrespect her. Callista understands emotions very well, and can often tell when someone is upset or bothered. She helps to ease tensions in the clan, and because of this, many adore her.
