Pink Dragons are primarily herbivores and only eat meat during the mating season, when mates will exchange kills. When it is not breeding season, pink dragons spend most of their time incubating eggs and caring for their clan’s young. Due to their feminine color, it was traditionally thought that pink dragons were a strictly female breed, but this is not true.

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.

When Zabeth found Fionn's egg, the unborn dragon inside was very near death. However, with nurturing and a lot of help, Fionn hatched safely and grew up. Even in her adult years of life, Fionn is rather small and her left hind leg is somewhat crippled because of her feeble state of health as an egg and hatchling. All the same, she is friendly and outgoing and almost like a younger sister to Estellabrist, who, although nearly the opposite of Fionn, gets along with her beautifully.
