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.

Against most of the clans' wishes, Xeelos said " An abandoned egg is an abandoned egg.", and let a Vampire into the clan. When it came time for Blight to get his name with the naming stone, the clan was shocked at how his name, Dante's Deceitful Blight, came out, for that was the fourth dragon in the clan to have a name that suggests that they belong to the Silver dragon named Dante. If Blight is not by himself, he's always with Dante, Jester, Imp and Cerberus. He rarely says anything when others are around, but when anyone tries to pin him down to a conversation, they would soon wish they hadn't, for he would go on and on about something concerning the end of the world, and how all life that wasn't "loyal" would be destroyed. His words, seeming so real, would give anyone who listened to them nightmares for weeks.
