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.

Sedv was given the adjective "Flipped" because of the curse he has. Instead of having no reflection, like normal Vampires, he is the reflection and has no physical form. He can only be seen when he is in the viewing area of a reflective surface. This is why most dragons tend to keep their eggs away from shiny dragons, as their scales are just the right kind to be one of  his "windows to the other side". He can come out of his "Reverse World" (as he calls it) once every full moon to bite any egg of his choosing. He can also interact with objects near a mirror, but can't cause harm to dragons near them.
