It was previously believed that purple dragons were exclusively female, but this is not the case. Recent environmental shifts have revealed the existence of both genders of this breed. Female behavior is well known; they are primarily herbivores but will eat meat during mating season. On the other hand, very little is known about the behavior and habits of male purple dragons.

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.

Mustache is weird. While other Separators are admittedly odd, perhaps a bit megalomaniacal now and then, they are nothing compared to him. Well known for his habit of stroking his mustache, proudly pronouncing that he has the "Most epic 'stache of all epic 'staches", Mustache is thoroughly fond of himself.

Needless to say, most of the Separators consider him a bit...off in the head. The one dragon that seems to understand him is Lord Glory, a small Night Glory Drake that both shares Mustache's name and his love of himself. The two often sit by the larger of the lakes--where Dr. Bones lives--and boast to each other of their 'many' amazing talents, and of how handsome they are.

Bones hates this, and often shows it by pelting the two with water whenever they are near enough to the lake's edge, or by calling in Splock and Kirkan to give the narcissistic Glory duo a long lecture about potatoes.
