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.

Asesinar's little experiment through and through, Ausente lives to please his 'father'. He is a sinister, malicious being who takes after his creator in an almost uncanny way, and Ausente is Empire's little golden boy to boot. His nature is no longer recognizable in any way as the White dragon he was going to become before Asesinar got a hold of him. Ausente loves to do all kinds of pain-inducing things, and Vidrio and Cazar quite honestly hate him. They plan on kicking him out of the Numeratis if his behavior does not improve, but seeing as that's not going to happen...he will definitely be booted. Asesinar and Empire will probably leave with their little vampiric lapdog as well, and the split in the Numeratis will have been all this cruel thing's fault.
