In the magic-noir world of the Dresden Files, wizards generally keep a low profile, though there is no explicit prohibition against interacting openly with non-magical humanity. The protagonist of the series, Harry Dresden, openly advertises in the Yellow Pages under the heading "Wizard" and maintains a business office, though other wizards tend to resent him for practicing his craft openly. Dresden primarily uses his magic to make a living finding lost items and people, performing exorcisms, and providing protection against the supernatural.[23]
