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.

Sirleaf's full name is Dekese Weinseil Mariam Ashleigh Short-a-Prong Topical Gel Sirleaf, but she goes by Sirleaf for convenience. She enjoys explaining her full name, since she was adopted by a family with a long tradition of giving a particular naming scheme to members. She really likes growing three kinds of hornbeams, plus a species of plant with purple striped flowers whose name she doesn't know, and seeing young hornbeam trees and the stripy flowers together in the Wrap Forest is a sure sign Sirleaf was in the area recently. The first thing humans almost always say to Sirleaf when they meet and introduce themselves is that they thought she would be male, and she is happy to explain it's a family name and where it originated and try to explain the rest of her name if time permits.
