What Is Sciomancy?
Sciomancy (or Sciamancy) is divination by observing the size, shapes and changing appearance of shadows or ghosts (shadows of the dead). When sciomancy pertains to ghosts, it is a form of necromancy (summoning the spirit of a deceased person for divination).
According to legend, projecting a headless shadow or no shadow at all meant the person would lose their life within the course of the current year.
