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. Aso dwell in the frigid waters of the far north and south, and are occasionally spotted near tundra shores and ice floes. Their isolated homes of choice suit their tendencies towards small family groups or being solitary. Their bodies are so cold they nearly instantly freeze anything they come in contact with, be it water or living creature. Over time, the ice that breaks off their bodies as they move forms into glaciers they use as lairs. The older an Aso is, the larger their frozen abode.

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.

Arktandos is the Alpha of the Aso Xenowyrms, being the eldest and largest of the batch. While solitary, she enjoys spending time with her pack, as well as occasionally visiting the main cave. She is also not above aiding a random dragon in need, provided she doesn't freeze them accidentally.

Finding a companion was hard for Arktandos, since her body is incredibly dangerous to most other creatures, but she found an Ice Dragon who also enjoys being alone. Together they huddle in their massive icy abode, basking in the frigid temperatures that radiates from their scales.
