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.

"More of what! What the hell are those things! Are those the hatchlings!"

Mistresses are the reanimated corpses of the dead, reshaped into horrific new forms by a recombinant extraterrestrial infection. The resulting creatures are extremely aggressive, and will attack any uninfected organism on sight.

The sole purpose of almost all Mistresses is to acquire more bodies to convert and spread the infection. They are believed by some to be the heralds of humanity's ascension, but on a more practical level are the extremely dangerous result of exposure to the enigmatic fangs of The Overmistress.

The Mistresses are controlled via The Overmistress. The Mistresses motivations are to create a mass of necrotic flesh to be collected by The Overmistress during Convergence, with the intent to create another Overmistress.
