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.

Unlike other Vampires on Master's scroll, Sound does not hunt in a stealthy, stalking, silent method. He is brash but very swift, engaging in a chase with his prey. If he does not successfully hunt it down like this, Sound emits a vampiric roar that blasts the escapee into paralysis. It is a combination of a bone-chilling shrieking and sonic blasts. He is a successful hunter; the other vampires look up to him as a leader but Sound does not consider himself as a dragon of authority.
