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.

Thilkyko Ropalo means Female Bat in a foreign language. She doesn't do much but mostly scare other dragons by hissing when they get too close to her when passing through the caves. She gets bad reviews from other dragons because of her biting problems to, she believes, make them into her own kind. There have been times other Vampire Dragons have made one of their own kind by biting an egg, but Ropalo has already killed a fresh egg when immediately biting it with excitement and hope that she will have a best friend of her own kind.
