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 a different type of mana, making them powerful magic users. Thalassas are a unique variety of Xenowyrm in that they are the only subspecies known to dwell in marine environments. Their porous skin and slender build are perfectly suited for the aquatic terrain, but they can only survive for short periods of time on land. Powerful users of water magic, they can create large waves and alter currents with a simple thought.

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.

The Captivating Princess is the daughter of a "traitorous empress", born in a year of great tumult and change. She is at home in the ocean depths, her eyes having adjusted to the darkness when she was a hatchling. She is fond of a kind of honey that gives the taster pleasant dreams, although "proper" folks turn their snouts at such a hobby. It's well-known that the Captivating Princess has a taste for anything edgy and disreputable—she wears scandal like a fine silk gown, if a huge, limbless sea dragon could be clothed. Nobody has a bad word to say about her, though. She is marvelous and an example to all, and don't you forget it.
