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.

O Tegami loves to grow flowers, and carries a bag of different seeds and sprouts wherever he goes. He pays particular attention to the colors of the blossoms he grows, and tries his best to pair together the hues that suit each other the best. On special occasions, he will create murals of wildflowers, arranged to form the shape of a dragon being celebrated by the clan or wooed by one of his siblings. Tegami knows that his flowers by nature are ephemeral, so he strives to make sure the beauty he spreads lives on in the memories of those who encounter it.
