Book of Shadows (general)

Books of Shadows are magical tomes kept by witches, containing spells, potions, charms, information, past experiences and general notes. As a rule, written by the Council of Elders, whitelighters are to have their charges keep their books in a sacred altar room, though Leo Wyatt did not apply the rule to the Charmed Ones. The most important book in existence is the Book of Shadows owned by the Halliwell family. Began by Melinda Warren during the late 17th Century, the tome contains centuries worth of information. The evil equivalent of a Book of Shadows is a grimoire.
