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.

Zero was just an egg when his world was changed forever. Bitten by an unknown vampire, his egg was rejected by the other dragons in his cave, and was picked up by his new owner. None of the dragons in this cave accepted him either, except a sunset dragon named Inaru SilverWolf, who defended the egg from the other dragons in the cave. Ever since, they have had a strong bond, and she is the only dragon he allows near him.
