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.

Hiapo had always longed for a sibling. Even from a young age he was a dragon that craved a certain amount of companionship. It was an urge that his parents couldn't satisfy; he'd never found a way to really relate to either of them. He didn't share his mother's love of fighting, and his father was no less irritable to him than he was to any other dragon. With no way to relate to either parent--and with neither parent playing what one would call an active parenting role--Hiapo found himself frequently on his own and lonely. He formed some friendships with other dragons, most notably Ho'opunipuni, who he later mated himself to. A quiet dragon, he is not quick to anger but he is quick to defend, and will attack any that he perceives is threatening his mate, or his children. Perhaps because of his own father's rather neglectful parenting, Hiapo has vowed to give all of his children as much attention as they will ever desire--and, in some cases, perhaps more.
