Warning! Dating a vampire may be hazardous to your health. Vampires are mythological or folkloric revenants who subsist by feeding on the blood of the living. The notion of vampirism has existed for millennia; cultures such as the Mesopotamians, Hebrews, Ancient Greeks, and Romans had tales of demons and spirits which are considered precursors to modern vampires. The designs here celebrate these creatures and are not associated with Stephenie Meyer or any Twilight books and/or movies.
