A mansion of vast mystical properties, it is not always situated in the same locale for extended periods of time. Mystical wards protect the mansion from unwanted trespassers, and other incantations are used to render it invisible to those untrained in the mystic arts. Recently, Shadowcrest has been appearing in the Gotham County region just outside Gotham City. While once the home of mage John Zatara, it has since been passed down to his daughter Zatanna. Zatanna maintains an extensive occult library inside the mansion and the house is staffed with faux servants created through magic. Another security feature at Shadowcrest is its voice recognition security system, a complex spell that serves as a "magic word" for gaining access to the front foyer. In recent times, Zatanna invited Mary Marvel into her home to help train her with newly discovered super abilities, but Mary's short temper and impatience made her unwelcome and she was forcibly removed from the premises.
