Al Basti (Turkish : Albastı) or Al Kardai is an ancient female spirit, the personification of guilt, found in folklore throughout the Caucasus mountains, with origins going as far back as Sumerian mythology.

In Turkish folklore Al Basti has been often confused as both a Mare, a Succubus, as well as any number of Middle Eastern female spirits which are told to enter a man’s erotic dreams. However, the difference in the Al Basti legends is that she is not a sexual spirit, she rather visits those “who have guilty souls” and “come from families that have committed bloody crimes that have gone unpunished.”
