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.

As a wyrmling, this dragon was thrown out with the bathwater. She wandered around for a long time, looking for either a way home or someone to foster her, but to no avail: none wanted what they knew would grow up into a vicious dark green. A sympathetic but overburdened human bemoaned her being "as unwanted as used bath-water" which led her to take up "Bathwater" as her name. She has grown spiteful of those who lack empathy and when she chances across an abandoned wyrmling—or one who has strayed alone into her territory, whom she thinks is abandoned—she will unbury herself to find a foster family for it. If the chosen family does not care for the wyrmling to her standards, she will exact revenge on their own children, usually by eating them.
