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.

Arvens is typical of other vine dragons, in that he spends much of his time hidden from view down in the earth.

He contributes very little to the pack's welfare—he leaves the hunting and guarding to others, only bestirring himself occasionally when he senses prey near enough to snare with his prickly vines.

Truth be told, most of his scrollmates forget that he's even around—but step too close to his vines and he whips out a sharp reminder that he is present, and awake, and NOT pleased to have visitors.
