 Normally appearing as old, withered men and women, or turning completely invisible except to certain medicine men, they take to the air in a fiery shape, with the sounds of a raven's cry and a strong wind as they hunt for their next victim.After tormenting and killing their victim by slitting the victim's head they consume his heart (doing so without leaving a mark on the victim's skin), and add a year to their life for every year that the slain would have still lived.The sound of a raven mocker means that someone in the area will soon die.
