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.

Nightgaze's Bloodthirsty Snarl, or 'Snarl', as Nightgaze nicknamed him, is possibly Nightgaze's Final Pulse's fondest admirer. He brings Final many gifts and such, but Final doesn't fall for it. He will not give up, however, and continues to try (and fail) to woo her. He is very talented at that, as Vampires are not exactly 'charming', in most dragons perspectives.

Snarl is supportive of biting. He says, "If A Vampire can't bite, they can't reproduce. How are we supposed to survive" Snarl isn't generally scientific like that unless it comes to Vampire stuff. Then, he aces.
