            The papers documented Lucius’s monitoring charm, and she saw that it was currently set to a radius around London, and another around the manor. Most of the floors at the Ministry were off-limits. The neatly typed instructions explained that the charm could be amended, and that either the radius could be changed using the supplied UK and Ministry of Magic maps, or the radius could be centered around another person—an Auror. That way, the subject would be beholden to stay in a vicinity controlled by a person, rather than a place, and they could move beyond a single radius as the Auror also changed his or her location. The Auror could also set additional locations where the subject was limited to, which would remain regardless of where the Auror was located. This method also appeared to override the Ministry restrictions, according to the instructions.
