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.

When she isn't guarding her family's underwater cache of water mana crystals, Kona can be found hunting for her favorite food, oysters, while making good use of her ability to magically redirect water currents. Occasionally she'll come across a pearl or a shell of iridescent sheen, and she'll save them for trading with surface merchants when they visit. She keeps the particularly nice pieces, to look at while she's prowling around the crystal vault on guard duty. Kona likes pearls with pinkish tints that resemble water mana, which reminds her that the beauty of nature can be regarded as a kind of magic in itself.
