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 "Chain Weeper". Silisili was created by Usiku, the coordinator of the Vampire dragons lead by MwakoNgozi. She regards MwakoNgozi with a mixture of caution and respect. The Ember dragon makes even her "father" bow down to her so MwakoNgozi must be of even higher authority. Silisili reluctantly will bite other eggs, not understanding why she must do this other than Usiku saying if she did not, then nothing but grief will come of the Vampires. Not wanting to find out what this chilling message means, Silisili carries out her "purpose for living" to the best of her ability.
