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.

Unlike most dark green dragons, Ximentha does not kill everything that moves. That being said, the only living thing (besides her mate) that she will not kill is her stead-fast companion, the mint dragon Vasiliy. It's not known how or why the two bonded, but she has never made a violent move toward the mint. She even seems to user her vines to shield the smaller dragon from anyone who may wish to do her harm. She is mated with another dark green dragon, Osmok. He, too, refuses to harm the mint, probably out of fear of his mate's wrath.
