Vampires are mythological or folkloric beings that are renowned for subsisting on human blood or life-force, but in some cases may prey on animals. Although vampires have different characteristics depending on which lore one reads, in most cases, they are described as reanimated corpses who feed by draining and consuming the blood of living beings. The term was popularized in the early 18th century and arose from the folklore of southeastern Europe, particularly the Balkans and Greece. Folkloric vampires were depicted as undead beings who visited loved ones and caused mischief or deaths in the neighborhoods they inhabited while living. They wore shrouds, did not bear fangs and were often described as bloated and of ruddy or darkened countenance.
