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.

Dead Problems insists that he's just like all the other dragons, except that he's dead. Being dead isn't really that big of a problem to him. Just because he's dead doesn't mean that he doesn't have problems.

He takes his revenge, gets into trouble, lies, "talks" to other dragons (mostly other vampires, but you know, they're dragons too), and basically acts like a normal dragon, other than the fact that he's DEAD. One of his favorite phrases is that doornails wish they were as dead as him. He uses that phrase a lot, just to cement the fact that he's dead.

But he definitely has problems too. Man, he's a dragon. He's just like all the other dragons, except he's dead.

That's basically a friendship turn-off for other dragons but hey, he's got dead problems too.
