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.

What started as a support group for non-zyumorph children of sinomorph and zyumorph parents soon grew into a team of would-be heroes. The members never stop arguing, nobody can agree on a name, and the "villains" they face are all largely playacting, but the group still strives to make its mark on the world. Kevtob has one of the more useful skill sets. At least once per mission, something is guaranteed to happen either too quickly or not quickly enough. Meisk is continually lecturing her about how, even if slowing the villain to a standstill is an effective means of ending a fight, she should really give her fellow heroes a chance to shine. Kevtob doesn't really understand why Meisk is more interested in spectacle than in efficiency, but grudgingly humors him.
