Altar Room

An Altar Room is where witches are supposed to keep and use their Book of Shadows, at least according to a witch-practitioner named Natalie. However, not all witches use or have an altar room.

History
The Elders have a rule that all witches must keep their wiccan books in a sacred room, and Whitelighters are instructed to ensure that this rule is followed.

However, Leo Wyatt neglected to tell the Charmed Ones, who kept their book in their attic. After discovering this, the attic became a sacred place where no mortal is supposed to enter without knowing the family secret.

In Destined, the attic is still the sacred place where the Warren Book of Shadows is kept. It still rests on its podium.
