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.

Kardryn is a bit picky when it comes to his den. He always finds something bothersome or uncomfortable in every nest he has set up and he always complains, saying he can't live and feed in these conditions. Either the land is too sandy, or too rocky, or it's just right but the worms are tickling him while he stalks his prey. Another spot, near a village, was too noisy. He can't stand the tight hills, as he likes to unfold his vines over a large territory, and the soil near the forest just smells funny...

Needless to say, this grumpy dragon has never settled in his underground lair for more than a week. That's ridiculous by vine dragon standards, and the others call him a foolhardy wayward. Even if travels are strenuous for him, Kardryn is determined to search until he finds the perfect spot. In the meantime, people have learned to take advantage of his habit and plant crops around Kardryn's abandoned lairs, as the ground is fertile and easy to plow there.
