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.

Whisk lives in the sea, but she does not consider herself a part of the Clan's ocean march; in fact, she does not consider herself a part of the Clan at all, despite the fact that she was raised among their caregivers. She is rebellious and adventurous in nature, if fatally so; though friendly, she has an unruly obsession with discovering something 'more' in the lands that lay beyond. She neglects her homeland and her friends, constantly roaming the world's waters in search of a solution unknown. She does not know what she hopes to find, but knows she'll find it eventually.
