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.

The Braid, a collective of dragons dedicated to making the world a better and safer place, got its name from its three interwoven goals of prevention, preservation, and restoration. Zyniek bypassed all three Strands and went to the Tangle, a thriving xenowyrm community, to study time magic and add her own research to the Tangle's library. By her reasoning, she could join a Strand and help a few dragons, or join the Tangle and help many dragons both in the present and in the future.
