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.

Zephon is more selfish than what he seems. He thinks he is the best and most important dragon in the cave, so he tries to stay on top. He doesn't cares about eggs and hatchlings, so he is not affected if his bitings fails to make a vampire hatchling.

Many dragons are sure he does have a soft spot, and they think that he is a very nice dragon once you get to know him, but his (almost) despise towards eggs and hatchlings has made him win the hatred of the dragoness Dreamkeeper. They try to keep as far away from each other as they can.
