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.

In the deepest darkest corner of the cave, among a pile of broken eggs, Vinyetto resides always smug and angry. He knows that every dragon in the cave hates him, he doesn't care, for they hate him because they fear him.

Vinyetto has a bit of a violent streak in him. He doesn't just bite and take what he needs, he will make a game out of it, playing with his prey. He will catch someone offguard far away from the rest of the clan and toy with them for ages, letting them wonder if he was going to let them live or not. Soon they would be begging him to leave or just get it over with. He takes there blood and then leaves them shaking and scared but always alive.
