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.

Heartless Fang is truly heartless. He hates company, terrifies young hatchlings, and if dragons don't keep their eggs far enough away, he will eat them simply for the joy of seeing yet another horrified parent. Because of his cruel tendencies, Heartless Fang is shunned by other dragons, even fellow Vampires. This, obviously, doesn't help his cruel behavior.

The only dragon that Heartless Fang likes to have around is the crazy frozen hatchling White Fang's Ghost, which he considers a kind of pet. Of course, White Fang's Ghost does have its uses to Heartless Fang, and Heartless Fang can often be seen whispering in White Fang's Ghost's ears that his current enemies hate White Fang, and then watching the ensuing madness with an amused gleam in his eyes.
