The effects will be twofold. First, a ward that will alert me when someone magical sets foot on the property. This is simple enough, one of the most basic wards possible, really. The second is an aversion ward to direct anyone with hostile intent elsewhere. It’s about as effective as a notice-me-not, in that anyone specifically looking to break into my home will still be able to, but at least this way mom and dad don’t have to worry about burglars.
