Black Sacrament

 is a ritual performed by one who wishes to contact the Dark Brotherhood, usually in the hopes of having a murder-contract satisfied by one of their assassins. The Night Mother hears the pleas of the invoker and translates the information to her Listener. The Listener would then relay this information to Speakers of the Black Hand. From there, the head of the nearest Sanctuary sends an operative to answer the call.

The Ritual
In order to perform the Black Sacrament, the invoker must create an effigy of the intended victim, assembled from actual body parts, including a heart, skull, bones and flesh. They must then encircle that effigy with candles. The ritual itself must then commence. The invoker must proceed to stab the effigy repeatedly with a dagger rubbed with petals of a Nightshade plant while whispering this plea: "Sweet Mother, sweet Mother, send your child unto me, for the sins of the unworthy must be baptized in blood and fear."
