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.

Gone Wrong was once the pet of an alchemist who lived on a small island away from others to conduct his experiments. He tried using Wrong's vines to create a panacea with little success. As the experiments continued, more and more of Wrong's Dragon Grass went to waste. Wrong was kept in a cage, away from sunlight and the earth. Because of this, his growth was very slow. When he finally matured, Wrong attacked and killed the alchemist. He freed the other Vine dragon who was being held prisoner there, and they took over the island. He is very wary of humans and other dragons. Any living creature that gets too close to the vines is quickly eaten.
