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.

Mamajusi isn't embarrassed by much, save his name. Damian assures him that it is merely from an ancient language, but the sound of it is enough to make the Xenowyrm cringe. He goes by "MJ" when possible. MJ is in a league of his own when it comes to intelligence, a fact that he doesn't let anyone easily forget. His brilliant orange and yellow scales are his second favorite feature, though he secretly envies the brilliant blood-red scales of Xenia, the Gemshard dragon. He spends most of his time in the desert with the dragons of destruction, who have a tendency to go wild when left alone.
