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 different types of mana, making them powerful magic users. Chronos are often considered to be the most elusive of all Xenowyrm subspecies: they live in the darkest and densest forests, far from civilization. They are masters of time magic, allowing them to manipulate the flow of time at will. It is said that Chrono lairs are protected by a field of magic that makes the minutes tick by at a slow pace for any unwanted visitors.

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.

This dragon may be withdrawn and normally tucked away in some wooded area, but when she wants attention, she makes herself heard. For instance, if the more sociable and well-traveled xenowyrm, Scalper, is in the area making trouble again, she will yell, "Oh, Scaaaalper!" in a singsongy voice, which can be heard kilometers away. She always knows someone's name, too, even if she's never met them, though if a person does not have a name, she ignores them. Since the dragon herself is unnamed, other forest dwellers wonder if there's some kind of connection.
