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 impression Ven has on those who meet him is that he is shy although this isn't true. Being a plant dragon means too much sun could be irritating. Why spend the day on the hard cracked ground when there's a warm moist cavern BELOW that uncomfortable cracked ground. This is exactly Ven's mindset and for that reason it is very rare one gets a look at anything but the plant tendrils that may protrude from the ground.

The only time Ven'll come up is to absorb the sun's rays and maybe snatch a few low flying prey animals from the sky. Other than that he's happy absorbing nutrients and groundwater through his green leaf-like skin.
