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.

Lily takes a lot of pride in the fact that her name is both feared and awed—she is a ruthless judge of her surrounding and the people close to her, and uses these skills to get exactly what she wants. Whilst she has (almost) never killed another dragon, there are... rumors... Especially about her relationship with her "groom", Ragnarok.

Lily turned her groom Ragnarok when he was a hatchling, and sees him as both her equal and her servant. Out of the rest of the Spooky Sids, she is considered the Halloween Queen, with Rags as her King—She never fails to scare another dragon out of their skin. She is secretly very scared that she'll distance herself from the rest of the group, and that Rags will leave her for good.
