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.

Pandora's Bosx is a quiet dragon. She will not say 'no' to an request for help, but the 'help' she gives is often not in the recipient's best interest. If peasants want their fields replanted after her mate Demigod of Hellfire razed it, as is a common request, the plants she makes grow bear only a limited resemblance to what was there before. She does not demand payment, finding enough joy in watching the hapless inquirers struggle with the ambulatory wheat, rapidly-growing giant zucchini, or whatever other botanical terrors she has created. She is moral to some level, so if the individual(s) asking for her help are genuinely in trouble, she will help them without any tricks. However, if she feels the individual is acting selfishly or greedily, she is prone to making potentially deadly plants—such as bloodsucking dodder vines and hug-roses.
