Mission This: Destroy The Lilitu

The Lilitu is Babylonian equivalent of the succubus. She is a
demon who steals the breath of babies, causes diseases and robs
men of their seed. If you believe in the literal existence of 
these demons you can convince your wife that your nocturnal
emmission was in fact the result of a nightime rape by the 
demon Lilitu, and guilt her into cleaning up your mess.
Name cognate to Lilith.
