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.

The phrozen one is called so because of her ability to freeze the life from dragons, just like the others of her kind. She bites many eggs, but only the ones that are not being adopted in the cave. Her owner carefully waits and selects the eggs, then watches eagerly was The phrozen one bites into the egg. There have been a few failures, but all in all, it's a good cause-the "transformed" eggs are put back for others to enjoy.
