A Slavic species of SUCCUBUS, the viechtitsa preys upon young men who are deeply asleep, causing them to be completely consumed with sexual desire for it (see ENERGY VAMPIRE). Oftentimes this passion and desire is so intense that its human lover dies, which is why its ideal, if not preferred, lover is another type of vampire known as a VOUKODLAKS.
