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.

Leila Tara, a young and very intelligent Vampire of Natasha's Cave's Vampire Dragons, is the second female Vampire Dragon, and by far the most 'noble'. She was the first Vampire Dragon of the Cave to successfully bite AND hide a Balloon Dragon egg, not breaking the shell or allowing Merageth (a Sunsong of the group who despises the Vampires) to take it away as many of the other Vampires did. Leila Tara has a long and complicated lineage, which she is very proud of. Of all her siblings, she is the only Vampire, and because of this she has never been able to meet them, but she's never cared to. She likes her life just the way it is, especially since Natasha spoils her due to her success with biting the egg.
