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.

Sunner Wyrm is a Lone Dragon. These dragons aren't a part of any specific group, but they live together in a cave. Sometimes, they even share meals, but most of the time they stay away from each other. This Xeno is a wise and calm wyrm, but in times of danger, he becomes a really furious dragon. He uses his magical powers much better than his mother; however, he has a defect—he sees the world orange. He himself is orange, but Sunner sees the world orange as well, so it's usually no wonder why he bumps into something that clearly stands out.

Sunner lives in the deepest part of the Lone Cave. Here, he is unbothered (usually) by other dragons unless they have a matter of urgency. Usually, a hatchling visits him, adult visits being more uncommon.

Sunner can make very close bonds with other dragons, so, despite his defect, he can become a very close, loyal, and helpful friend to all.
