Bloody Mary, also called La Llorona - the Crying woman, is modern urban myth among children found in many places around the world. The details vary exactly, she was a women wronged by a man, she was the Virgin Mary who now leads an army of demons against God, she was witch and still has retained her magic to the grave and many other variations. One thing is constant, the method of her appearance. She comes when summoned, appearing in a mirror to the summoner who must have repeated her name three times. Once summoned she might answer a question, but having got her attention nothing but bad things can come of it. She may attack the one who has called her, either to disfigure or kill. Alternatively she may curse them and cause them great misfortune.
This isn't her only interest in children however. Some believe that she hates all children and does everything she can to make them suffer. Some she targets particularly causing them to meet unfortunate and bloody ends, others she exerts influence on more subtly, leading them to a life of drug addiction and crime.
She appears as a women clothed in billowing black clothing, with a blood red rosary. Her most distinctive feature is her lack of eyes, instead she simply has empty eye sockets that weep blood.
Some Mages speculate that this is just one appearance of a spirit who can be called from chanting over a mirror, just a current variation of an old theme. Of course that doesn't make her any less dangerous.
