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.

Constantly restless, Ame is almost always in flight and rarely descents below cloud level, even during the worst of storms. Whenever natural lighting strikes in the clouds, Ame follows with a burst of magical electricity of her own, as if goading the storm. Some whisper that she has become enamored with a being of storms manifest, and so screams her challenge to the skies to judge her worthiness as a companion. Others think that she's just trying to prove she's more dangerous than any lightning storm. Of course, no one says these things to her face.
