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.

Terror Lord was the name the dragons of the cave gave this Dark Green dragon. She was never given an official name since she despised every one given to her. On the outside she is quite violent and demands authority to be made when the slightest thing goes wrong in her presence. She doesn't like most other dragons so she hasn't had a mate. Her plants are secretly, as much as a snapping flower can be, spread all over as far as they can go around her area of the cave and also out siding area. To her annoyance a group of dragons have been replanting the plants she destroyed. She always eats them all over again before they bloom. One single flower though has not been attacked, and she always makes sure nothing touches it. Despite not having any real water sources than the rain and good grip on the soil, it has stayed for as long as Terror Lord has claimed the area. She hasn't been seen since the beginning of Glace's off days. Her plants and destruction have also stopped.
