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.

Thaelyaa, the second daughter of Vyvaldya and Culakther, is shy and not particularly friendly. There are a few dragons she doesn't mind socializing with, but generally she keeps to herself in the far corner of the cave. Incidentally, she is Culakther's pride and joy, and he is always boasting about her beauty and intelligence to anyone who can bear to listen. No one else really likes her—her great grandfather Venerelda despises her, for whatever reason. She's also not particularly fond of children.
