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.

When the human caretaker of the Brood picked up a vampire egg, she had no idea what she was in for. First of all, when Kol finally hatched, it took him FOREVER to finally grow his wings. When his wings did grow in, he began making a very strange noise whenever he was active. His owner, finding this all very creepy, decided to name him after the sound he still makes whenever he wishes to communicate.
