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.

Born at twilight, Liei had a terrible curse placed upon him from the moment he was born. He sparkled. Nobody could explain this phenomenon, but Liei twinkled like a star all day and night, making it uncomfortable for him or anyone around him to get any sleep. This problem has haunted him throughout his life, as hunting prey is so much harder when one is illuminated like the moon on a clear night, since any creatures for miles can see him and stay far away. This results in him becoming surprisingly unpopular, as nobody wants to be around a dragon who they have to wear sunglasses to look at, and poor Liei cannot even hide in the shadows in shame, so brightly does he sparkle. He has tried everything to get rid of his infliction, from ingesting strange herbs to trying to whack the sparkles off him, but to no avail. It's almost a relief that Liei cannot see his reflection, for he will never have to see a sparkly vampire dragon.
