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 out of ashes of an egg bitten by a vampire from the clan, he acted like the night itself, and still does. He traveled in the shadows, where no one could see him. Some called him "shadow", others "invisible". He didn't care about his new nicknames, even though Curse had given him the name Virupro, he thought everything everyone called him was equally fitting. After all, he was the invisible shadow in the night, and his name was Virupro.

Yicesla was his twin sister, and they had a younger brother, Capheru. All three of them were raised by the members of the clan. He and his siblings were happy to have each other when young; it made them feel less lonely since no vampire acts like a "normal" dragon all the time, and they're still as close as they were back then. They stay together all the time.
