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.

Knots in Green is evil, but in a good way. He burrows into the ground and stays there for long periods of time, eating  anything that crosses his path. He does have a playful side and helps the hatchlings train to become better fighters, popping out of the ground and tackling them to the ground and playfully biting their neck before going back into the ground. He does have a rather short temper and it is not suggested to walk across his hiding place when he's hungry or in a bad mood. More than one hatchling has fallen victim to his hungry jaws. He seems to have a soft spot for Slick Lizard, who almost got swallowed by his jaws, but stopped before he did, shocked at her beauty.
