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.

Amor Morder is the snake in the grass of the Numeratis. She's a deadly mix of Empire's malice, Vidrio's will, Cazar's subtlety, and Acosar's brutality, leading her to be one of the most feared of the Numeratis. Morder is just the kind to sidle up close to you, make you think she's your friend, and then stab you in the back. She has recruited Aranazo as her henchman, and the two both try their hardest to ruin the Numeratis principles laid down by Vidrio and Cazar. Whereas the founding pair both only turn eggs to ensure that they live, Morder and Aranazo inject more venom than necessary to purposefully kill the eggs under cover of accident. Even as young as she is, Morder will only grow to be more of a threat, and some of the horde has contemplated putting her down in order to save the future generations of the horde from her taint.
