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.

A long time ago a band of four dragons tyrannised the farthest corners of Galsreim, killing dragons and humans alike, creating fear and panic wherever they went.

Among the four Xenos, Methos was the most clever and cunning. Where their leader Kronos had a vision, Methos had a plan and the two of them were closest among their little band, lovers that couldn't be stopped by anyone. Only after meeting the Pyro dragoness Cassandra, Methos began to remember that he hadn't always been this way, that his love—his obsession—with Kronos had slowly warped him into a crueler and ever crueler dragon and he decided to explore what kind of dragon he would turn out to be on his own. He made a plan to split the four of them up and make it impossible for them to reunite and after getting rid of Kronos, he ran and hid.

To this day Methos hides among the Magi dragons of Delirium's Academy, studying, leading the quiet life of a scholar and he likes it a lot better than killing and maiming.
