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.

Even as a hatchling, Nemul loved to tease and prank her "siblings". Raised alongside three other female hatchlings by the human girl named Flight, Nemul enjoyed causing mischief at every corner. Her favorite victim was her younger sister, Tetlir, a Pygmy dragon. Often, Flight found Tetlir crying after Nemul went too far in her teasing, with Lillias, Nemul's Swallowtail sister, scolding Nemul while she turned away. All of the dragons cared for by Flight know never to tell Nemul anything secret, for she will most certainly find someway to make the secret public. Many times her siblings have tried to pay Nemul back for her countless pranks with some of their own, but they always end up tongue tied after the Pink dragon gives a mischievous reply. Nemul's favorite topic is crushes, and she enjoys spying on her brothers and sisters while trying to match each of them up. Nemul herself has never fallen in love, and most likely never will as she is too busy causing mischief.
