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. Gaia, despite their large size, are the lightest of all Xenowyrm subspecies. They possess the ability to use incredibly powerful life magic, though most of their efforts are concentrated; to them, nothing is more important than letting plant life thrive. Adult Gaia will use their magic to grow vegetation around themselves so they can spread it wherever they travel.

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.

Serene and delicate, Everett is the gentlest and wisest of giants. She's an elder Xenowyrm, having lived for many thousands of years and has watched the world around her change in that time. She is highly attuned to nature and plant life, specifically. It is widely believed she has the able to communicate with plants, though this is only an unsubstantiated theory. What is known is that Everett travels all over the world, even braving deep oceans and deserts, to transport dying plants to fresh soil. She's always careful about what plants go where and what ecosystems they affect. Often times, she will remain in a certain area where she has transplanted something in order to regulate the ecosystem and ensure it does not become unbalanced. Everett herself in not a very social dragon. Her passion lies solely with plants and the world itself; she cares little for other dragons or humans. If any try to interact with her, they usually won't get a response or even acknowledgement.
