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.
Fengolio is the main male in the Never lair and he feels rather protective of the younger dragons and would do anything to defend them, even resulting in violence. He cares a lot for his children, even the ones not kept by Never.<br/>As the first dragon to be hatched in the cave, he is cared for a lot. The other dragons sometimes feel like he gets special treatment; he of course, knows this isn't true - not that he is going to tell them that.
