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.

Saki is the "gardener" in the group due to her breed with naturally grows plants around her. She is responsible for the beautiful flower-bed that can be found around the place where the group stays which gives the sweet scent that everyone loves. She was exiled from her breed as she hates the violence that her breed members usually indulge in. Instead, she is very docile and have quite a timid personality, rarely attacking unless she is provoked, preferring to hide under the soil and layering traps to protect the place where the group stays. In battle though, she employs the use of her tentacle-like thorn vines which she use much like a thorn-whip, crushing them in its grip or simply slicing them into pieces. She got along best with Arata and used to working together with him in battle.
