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.

Rayfern was the firstborn of her parents, making her a Diamond among the jewels. Closest to her was her sister Mitrique and they were inseparable. Growing up, Rayfern was astonished to discover that she was unlike regular Dark Green Dragons and felt fearful that other dragons would shun her for it. Luckily, Mitrique was a "normal" Dark Green Dragon and she assured Rayfern that all was well. Rayfern grew quite attached to her younger sister after that point and the two spent a blissful hatchling-hood together. It's because of this that Rayfern was crushed when Mitrique died while still a young hatchling. However, Rayfern grew stronger from this experience and now cherishes the time spent with all those close to her. As the eldest of all her siblings, Rayfern is very protective of them. She acquired this trait from her mother, Junsai, a Guardian Dragon. This characteristic, mixed with the temper she inherited from her father, makes Rayfern a formidable foe.
