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.

Sampiro is the third vampire that joined the vampire tribe; he was bitten by the second vampire, Striggoi. Sampiro often goes on biting sprees and must be restrained by Striggoi so he doesn't wear himself out to the point of exhaustion. In an attempt to curb Sampiro's alarming behavior, Kikongo the magi dragon put a spell on him so that he could only bite once every 31 days. Though Sampiro was furious at the limitation, he has found a way to increase the vampire tribe's population without biting. He simply sits at the bottom of the cliff, waiting for other vampires to bite and for their newly-created minions being chased away by the other dragons. He catches the eggs and raises them, an odd show of paternity for a vampire. It may be strange, but it is effective. Sampiro has caught a grand total of 3 other vampires from the cliffs and by the looks of it he will definitely catch more.
