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.

Relaniel Oreth is the mate of Aeldur Tathdel. She keeps herself busy tending a large garden deep within the Cave, near the water dragon Silwen's lake. She enjoys tending her garden above all else, including being with her mate, and uses gardening as a substitute to attacking the other dragons, though they don't see how it's anything alike. She despises hatchlings, and has been known to try to sabotage eggs here and there, so the others learned quickly to keep eggs and hatchlings in the Upper Cave and on the far side of the underground lake. Most don't understand her, but Aeldur seems to be the only dragon in the cave who can see why she does what she does.
