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.

The legend of the Dark Garden is one steeped in blood and destruction. Nearly 400 years ago, near a small village in a land were the word "Dragon" was unknown, a mysterious green egg was found in a forest clearing. At first, the egg was treated as a curiosity, but soon it was found that the strange vines that grew on the egg, had the ability to cure many diseases, and soon a cult was formed around it's presence. The cult worked for close to a century, harvesting the vines from the egg, and the small village boomed into a large city, known throughout the land for it's medicine. But soon the King of the land heard rumors, of how the cult was secretly sacrificing people to sustain the egg, and Marched a army to the village. But when the King and his army arrived, they found nothing but a empty city, overgrow with vines. No evidence was left that anyone had lived there, but a large empty eggshell, and the sharp tang of blood in the air.
