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.

Mivario is a sweet and caring dragon. She never wants to fight anything, even if her life is in danger. She loves raising abandoned eggs and baby dragons until they can take care of themselves. She is usually never sad about anything, except when a death occurs. She is a life long friend of Ecario and is usually seen around him.

Mivario's egg was laid in a forest cave. On the day she hatched, her parents were killed by a dragon who was desperate for food, so she never got to know them. When she hatched, she crawled out of the cave to see the world outside. She met Ecario not long after, and the two stuck together and managed to live. Now she will spend her time looking for abandoned eggs and babies to raise so they will have something to call 'mom'.
