A vampire is a mythical being who subsists by feeding on the life essence (generally in the form of blood) of living creatures. In folkloric tales, undead vampires often visited loved ones and caused mischief or deaths in the neighbourhoods they inhabited when they were alive. They wore shrouds and were often described as bloated and of ruddy or dark countenance, markedly different from today's gaunt, pale vampire which dates from the early 1800s.
