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.

Caerphilly is shy; she doesn't venture out much.  She spends her days with the hatchlings, telling them stories and in general keeping them out of trouble. She has only one son of her own, with Bridgend; but Bridgend has shown no interest in monogamy. Caerphilly is willing to wait for him, though, and while she waits and hopes, she weaves fantastic tales of the world she's hardly seen, to entertain the little hatchlings that belong to other Dragons.
