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.

Fleptherko makes his home in the clan's bog, neighbor to Vatten Bado, a water walker. Submerged in mud, his dangerous tangle of vines are covered with a sticky substance, like that in a venus fly trap. Whenever an animal comes near, he will tighten his vines around it and pull it down into the thick mud. In the fall and spring, his vines sport bright orange leaves, but in the winter and summer, they are a deep green. Very few have ever gotten to know him, and hatchlings are now forbidden to go into the bog without being accompanied by the Mistress.
