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.

Windwraith Island is said to be haunted by the ghost of a vengeful wizard who calls storms to sink any approaching ships. Survivors will tell of how the sea went from calm to instantly deadly with no warning, with lighting striking from a clear sky to finish what the waves started. In truth, the unnatural behavior of the ocean is due to Faelt, who just wants to keep humans away from the island. He has no particular love for humans, though they've done him no wrong, and is devoted to his temperamental astrapi mate.
