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. Mageia, found exclusively in desert regions, are thought to be the wisest Xenowyrm subspecies. Due to their knowledge of the magi element, they are able to cast a variety of magics, including teleportation. Their beautiful yellow scutes are reflective and smooth like glass, making them very valuable to collectors.

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.

Shougen takes everything a bit too seriously, constantly trying to look at every angle of a scenario and spending hours carefully dissecting meanings in words usually spoken offhandedly. While this habit helps him out substantially when he is solving conundrums in his stratagem texts, Shougen's imperative demeanor keeps him from making any lasting relationships because of his inability to interact normally in social scenarios. Nevertheless, whenever someone in the Sylvain clan is beginning to doubt the faithfulness of a friend or mate, they can talk to Shougen to see what he thinks of the situation. Even if his deductions are not particularly reassuring, his more far-fetched predictions of possible outcomes always promise to be entertaining.
