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 he finally grew up, the Black Dragons gathered to celebrate the new Vampire Dragon. Sastan is the second vampire of the ArhDemon family and the 3rd generation coming from the alpha pair, Satan X Occultess.  

Satan, the keeper of the cave, entered and came in front of the Vampire dragon. "Welcome to our family, Sastan, may your bites be successful". Like all the Vampires of the ArhDemon family, he is forbidden to bite other eggs than the ones coming from the family. To earn the respect of the dragons, one bite during full moon must be successful. If he fails, there will be no more generations, and so the ArhVampire line will die.
