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.

Kyoushu, along with his cave-brother Kaishi, prefers to dwell within the darkest shadows of Hari's cave.  Due to his penchant for skulking about during the night hours, his existence within the cave is legendary—several of the dragons deny his existence entirely, believing him to be nothing more than a shadow on the wall or a figure seen briefly in the corner of one's eye.  The evidence of his existence is revealed only once a month, when he slips past the nest-guards like a silent specter and bites an egg, leaving its fate to be discovered when the morning light filters through the hole in the ceiling above.
