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.

Her name means "Blood be dead". Damu is one of the more morbid Vampires in the Night Raiders. Upon seeing that the Vampires were no match for that horrid Marrow and his minions, Damu was the first to surrender, and the first to be bound in chains. After witnessing Damu betray her "family" the other Vampires had attempted to kill her, that is, only to realize that they all were frozen stiff by some unseen force.

Despite her compliance with Rnachllac, Damu was given no special treatment, she was locked up in the prison of Scorch-Blood with the others all the same. Every night the Vampires are permitted out of their cells, but chained or under heavy guard. They are all expected to carry out their duty; kill any hatchlings that are out after dark, and to convert or kill any eggs that they come across.
