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.

When Budscale was born, his mother Jagaia had very little time to raise him, so her friend Vineprickle, a Dark Green Dragon, raised Budscale. Unfortunately, spending time around Vineprickle caused Budscale to grow plants similar to those of a Dark Green Dragon, which are supposedly dangerous and poisonous. Many dragons assume that Budscale's father is Ohmvolt, but his father is actually Phasesight, and only Jagaia knows this.
