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.

Her name means "To enslave spirit". Mtumwa was told a legend of that foul Marrow, Rnachllac. It was said that he used to be a kind dragon, that is, until he sold his soul away to a old Black dragon. After that, evil comsumed him, making him ever so eager to control and kill.

Unlike the rest of her sullen "family" Mtumwa tries to find the positive in any situation, even if it's so small only she could be able to find it. When she is let out to search for eggs to bite, Mtumwa is given the most freedom (though Rnachllac does't know this). The dragon that is suppose to keep a close eye on her found himself rather fond of this strange Vampire (positivity was almost never seen at Scorch-Blood). Mtumwa can do mainly whatever she wishes when she is let out, and she does just that. As thanks for treating her so kindly, Mtumwa brings back small treats for the guard, such as a piece of meat, or the occasional flower.
