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.

Current Princess of England is the current princess of England, the Land of Engs. An eng, according to the princess, is a wise and believed-to-be-long-extinct species of bird that was a symbol of magical might and good fortune, and she's the only surviving family member, the great-great-plus-a-few-more-greats grand-niece, of the king who held dominance of these powerful creatures, hence her right to rule this land that nobody seems to know the boundaries to. Most of her "subjects" think she's making all this stuff up, but they don't want to argue with a xenowyrm who stares creepily at people.
