Vampire Dragons are members of the undead. They sustain themselves by drinking the blood of others. It is said that they are only “alive” at night, and seem dead or asleep during the day, as they cannot endure sunlight for long periods of time. Vampire Dragons can only reproduce by changing the eggs of other dragons, puncturing the shell with their fangs and injecting venom that kills the baby inside.

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.

Yamarakura presone has an excessive desire for ease, even at the expense of others. Yamarakura is unwilling to do his chores or tasks that his scroll master gives him because of the effort it takes to do it. But after persistent threats from his master he will do them nevertheless in the end with a grudge. Yamarakura is bad at everything that would require maintenance, refinement, or support to continue to exist. He's even been on the verge of death because he was to lazy to hunt. Pierre is often seen as the personification of sloth in his clan. If his egg wasn't bit by a Vampire dragon he would have grown up to be a Balloon dragon. While most of his clan is afraid of most of the vampire dragons, they are relaxed when they are around Yamarakura. Despite criticising him regularly for his lazy, aloof and apathetic nature his clan does admire his carelessness and somewhat carefree take on life. Yamarakura lives a very hedonistic lifestyle with no regrets of his opportunistic actions.
