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.

Bygek is the leader of a collective of vampires who seek to conquer the world by converting every egg they find. She alone is not part of the collective hive-mind, as she directs and controls the others, and so she is the only one with a distinct personality. Bygek is charismatic, even charming, and dangerously persuasive. Even logical Dasoong wavered, though only briefly, as to whether or not to aid her. Though resistance is generally futile, Bygek does have one weakness. As she is still ruled by emotion, she can still be provoked into acting irrationally.
