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.

Like his father, Fitz is a dragon almost bigger than life. Whether he gets involved in the latest independence war or lets himself be dragged into one of his friend Amanda's schemes, Fitz's life is anything but dull. And there's usually some kind of lady dragon involved. Fitz isn't a dandy and lighthearted womanizer, though. He truly and deeply falls in love every time. He is absolutely serious about it when he swears he wants to spend eternity with a dragoness. That is, until something else happens and he gets distracted. Or he stays with a dragoness long enough to get bored. Or he falls for someone else—absolutely and truly, of course.
