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.

Delila was surprised to find that she was the only female in the first litter of Lancer's eggs. She soon fell in love with Bob, and she has never bred, nor will she ever breed with, any dragon other than Bob. When she was young, she didn't seem content with the sort of things the other purple dragons enjoyed, and always looked for more adventurous things. She still has yet to find the one adventure to tell for ages to come, but insists that it must be out there somewhere.
