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.

Hokai Kusa Midorikyutai, meaning Decay Grass of the Green Orb family, is from a long line of pure blooded dragons, making him a very proud family father. Hokai is the only one who can keep his family's overeating habits at bay, and although he cannot control his mate Akai Toge's tastes, none of the family is allowed to eat children or pregnant mothers of any species. Those that disobey Hokai's sole family rule have a rather distasteful habit of disappearing.
