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.

"One that carries night soil."<br/>Koekumi is a young dragon of the night and one of Negami's best dragons. He and his brother, Satsukiyami, came into Negami's care one dark hollow night. While out on night patrol Negami found the two odd eggs and brought them home. Both eggs were adopted by Urame; who raised them as her own. The two brother vampires now act more like black dragons more so than vampires. Koekumi loves to do night patrols, and loves it even more when he gets the chance to scare off would-be intruders. The sight of a vampire dragon can scare off even the bravest of dragon hunters.
