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.

Thanos lives with Jenneta's other vampires in a big cave not far away from Jenneta's other dragons. Thanos really enjoys them a lot, especially the young ones. Thanos loves playing with the young ones, wrestling with them and playing hide and seek with them. Thanos is a very touchy, protective, miserable boy. The reason why he is so miserable is because he misses his original owners, and his parents, and wishes he could be with them- but he can't because he don't know who they are. Thanos at times gets jealous of the two oldest vampires- Diabolos Lamia Dhampir, and Vladimir Vadim Valeray simply because- they have children and he doesn't. It's Thanos's dream to have a lovely mate and kids, a lot of kids. Altogether, Thanos is a loving wanna be father with a big, sadly miserable heart.
