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.

Sign is a major adviser to SunStar, one of the leaders. He is a very spiritual dragon, and has his own cave that he does not have to share with anyone. He also has his own fountain at the back of his cave where he performs his mystic activities. He rarely has visitors, and when he does it must be very serious. When he's not in his cave with his fountain, he's out talking with the leaders about the things he sees in the pool at the bottom of the fountain. His only real friends are SunStar and MoonStar.
