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.

Therapea amatos, literally translating to "Blood Stealer" from greek, fits them well. They act friendly to new additions to the cave, tricking most dragons into thinking he is nothing like the other Vampires. When the dragon least expects it, they'd drink some of their blood, then leave to trick another dragon. They seem fairly fond of their caretaker, who is only known as Shade, most likely due to the lack of punishment or restriction when they 'accidentally' get into where she keeps her eggs and bites one, more often than not killing the egg without success.
