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.

Considering his hateful, agressive mother and his quite indifferent father, it's bewildering how Thicket grew up to so submissive and kind. The young Dark Green dragon often gets yelled at by his mother for being too soft, and he can often expect "surprise training" in the form of his mother attacking him out of nowhere. However, he never seems to mind his mother's antics all that much. Thicket loves to travel through the vast network of tunnels and burrows he's created, and he delights in popping out of one of his burrows for a minute to see who he'll meet! The young dragon is loyal to the friends he makes in this little burrow game, and they are just as loyal to him (or at least he likes to think so).
