Originating from a single species that thrived in ancient times, Xenowyrms have become an incredibly diverse breed whose appearances vary depending on their habitats. Each Xenowyrm subspecies is heavily reliant on the power of different types of mana, making them powerful magic users. Astrapi are easily the most temperamental of all Xenowyrm subspecies. Their unpredictable behavior—coupled with their masterful control of lightning magic—has the potential for devastating results. Most of their time is spent airborne, flying through the skies or circling mountainsides for prey.

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.

Miki has a bad habit of picking fights with large predator birds that live in the areas she flies through. Most of the time she finds the falcons and eagles below her attention, but she's not above having a hissing match with a bird of prey encroaching on her airspace.  Rarely does she feel the need to stun a bird with her lightning magic, but sometimes when she's particularly grumpy she'll conjure a cloud of sparks to accompany her when she goes hunting. The rest of the family has learned to avoid her when she's in one of those moods.
