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.

Quiet and stately, Uta makes her home in the forest near a ritual circle site the Sylvain clan dragons use for emergency healings. She keeps away pests and predators using her time magic, and checks the carved ritual diagrams each day to make sure they're not starting to fade or wear away. Most of her interaction with other family members is silent; she generally prefers to watch from the side rather than engage others directly in conversation. Few Sylvain dragons even know that Uta is part of the clan, though those who visit her ritual circle are usually able to catch a faint glimpse of her.
