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.

Akoko was raised mostly by Adine when her egg was found, a surrogate of Adine's own lost egg. It shows in her nature. She has none of her surrogate mother's rough outer layers, only the inner layers of kindness. She is submissive to the wills of her elders, happily going about her duties. Her duties are to be lairmother to the eggs and hatchlings collected or birthed, and she is delighted to be of service. With Alaunus to help, she takes great care of all the lair's young, wishing wistfully for some of her own. She is greatly taken with Alaunus, and offended that Syrieth snubbed him once. However, now that young Ermir has grown up, she has found the one who would protect her no matter what and while Alaunus is her best friend, Ermir is her heart.
