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.

Inspector Taf is the head of the clan's newly founded crime task force. His first and foremost duty is to determine if there really was a crime committed or if the dragon in question just misplaced part of his hoard. His second most important duty is to discourage Pegasister from blaming everything on the psychopathic algae. If he still has the energy afterwards he deals with the diplomatic interchange with the humans living on the clan's lands to identify the culprit.
