Book of Vile Darkness

You contact a creature with whom you are familiar and send a short message of 25 words or less per sending. The target believes the sending came from another creature that you specify at the time of casting. You must also be familiar with the creature you want your target to think is responsible for the false sending.  The target can respond if they choose. The spell does not force your target to believe what is said. If you say something that is unlikely to be said by your false sender, the target may think they are being contacted under duress.
