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.

Dianiia has a very unusual temperament for a vine dragon; oddly protective. She allows small creatures to nest amongst her vines, given that they don't try to nibble on them. Likewise, she unleashes her wrath upon anyone who threatens nature, using those same vines to attack and destroy. She is slow to anger, but slow to calm, too, like the fury of nature itself. The area where she makes her home is more of a paradise than the typical barren, lifeless stretches that give away the locations of other dragons of her type.
