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.

Being the first dragon of Doll's collection Bittersweet understands what it is like to want another similar to oneself.  She is the first to weather a storm and openly offer a spread wing to any dragon of her group.  She encourages the other females to leave the defending of the home to the males so that they can come together and nurture the eggs and hatchlings that are laid or collected daily.  She looks forward to growing old and watching hatchlings, grand-hatchlings, etc. grow up and start families of their own whether they be in her families cave or another cave.
