The Fidelius is a spell to hide the knowledge of an object.

Usage Edit

To make a fidelius place, you need to place wards to set up a perimeter and then cast a charm.[1] The spell can be applied by strong wizards and one wizard had a limited amount of fidelius he could apply. By applying the fidelius one uses part of it's soul and thus it limited the amount.[2] The secret could be revealed by saying the secret, someone reading the secret on a piece of paper or using a spell within the fideliused area and someone seeing it coming out of it.[3] Additionally wand-tracing doesn't work under a fidelius.[4]

One of the theorised weaknesses of the fidelius charm is that the more you knew about the area under the fidelius, the stronger its power was. By knowing less, you could technically faster find about it than someone who knew more.[5]
