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.

Pablo berrytree is seen to be cold, heartless and cruel, driven primarily by wealth rather than the well-being of others. It appears that he has a softer side and that his cruelty is a means of coping with the years of hard decisions he has to make. Pablo can grow berries and alter the effects they have, making them either for example deadly, sleep inducing or causing amnesia. Because his clan is afraid that when some clan members decide to leave the clan that they may get captured by rivalling clans and get interrogated for top secret clan information, Pablo is given the task to give these dragons his amnesia berries. Pablo gives these berries to dragons that can't be stopped to leave the clan for personal reasons, his clan's dragon spies, raiding groups, etc. Even though the berries give selective amnesia and lets the dragon keep his other memories that don't endanger the clan, Pablo can't help but feel like he is going to far. So he wonders constantly if the ends justify the means.
