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.

Ydunn was found by Clan Ereal's trainer among a pile of abandoned eggs.  Small and scared, she refused to make a peep and shivered in fear at being carried away from the home she'd known.  They arrived at another cave, and she was shown another Vine dragon, Verthandi.  Immediately, she felt comforted and at home, and cooed happily at finding this new partner.  Ydunn can sometimes be caught chirping out pleasant tunes as her vines coil among Verthandi's.
