Perhaps among the most venerated of dragon breeds is the Zyumorph, a breed whose selfless heroism and strong moral compass are nearly unparalleled by other dragons. Zyumorphs have an innate urge to fend off wrongdoing, and as such, are often sought after in times of peril. Although they are independently quite capable fighters, it is said that their true might is not unlocked until all six Zyumorphs are brought together in times of great duress.

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.

Fausterion is a fierce assassin dragon. He, along with Mephistophelios, often flank the enemy from behind, resulting in a complete victory almost every time. Although a very strong dragon, he's still learning the basics of attacking the enemies precisely on their weak points. During peacetime, however, Fausterion NEVER plays with his fellow packmates, but rather practices alone in the training fields. He is very stubborn and selfish in nature, but he secretly cares for his fellow packmates.
