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.

Found as an egg, resting in the middle of the woods, Khezef's owner actually thought the egg was a flowering fruit at first, until it hatched into what he thought was a dead dragon. When it started to exhibit tendencies similar to Glypha, his owner briefly believed Khezef to be a Nocturne Dragon...until the blood drinking began.

After a particularly gruesome fight between Khezef and Eugene, his owner started to take extra care to separate Khezef from the others. Giving him his own section of the cave, and giving him small dishes of blood, usually cow's, Khezef eventually reached adulthood without further issues.

Strangely, he seems absolutely terrified of Daegot.
