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.

Stephanie Plum is a dragon fascinated with intrigue. Problems of all shapes and sizes capture her interest, and she won't give up on a mystery until she finds out the answer. Due to this, she can be somewhat headstrong and frustrating to the other dragons, because like everything else, chores are also a lower priority than mysteries. However, her knack for following the clues to an eventual answer makes her a valued, if a bit tiresome, member of her tribe.
