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.

Raiila has abandoned her duties in favor of isolating herself with her mate, an Omen Wyrm known as Echopraxia. The dragons of the cave question why she would ever love such a frightening and dangerous breed, and Raiila doesn't bother telling them. She knows her mate, and that's all she needs to know why she loves him.

Lithe and graceful, the Chrono spends her days exploring and dozing with Echo, telling him epic tales, which she is quite skilled at, and playing around with her time magic. Vandarus calls her irresponsible, but Raiila believes that she shouldn't be constrained by an obligation placed on her at birth, to which she didn't agree to.
