Dark green dragons, once they mature, appear to become an entirely different species. However, this isn’t true. Rather, they burrow underground and get nutrients from their vines. These vines are sometimes referred to as Dragon Grass. These dragons are very violent, and will use their vines to capture, kill, and eat anything that moves, as well as nearby plants. Luckily, their range is limited and they cannot use magic. Dark green dragons tend to be easy to spot since they usually kill all plants around them and thus are usually surrounded by a large clearing.

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.

Jarila is the middle child, and often feels ignored. In order to combat this, she pulls pranks nearly all the time. Although some are harmless, most are viciously intended, and animals or other dragons often get hurt. She is constantly imagining that others are saying things behind her back, and this is fairly well-based since she is feared by some of the others. However, they smile to her face, afraid that she'll harm them if they openly express their dislike, so she has no idea who her friends really are.

Jarila is the female equivalent of the Slavic deity, Jarilo, who was associated with plants, spring, fertility, harvest, and war.
