Unplottable Magic

The ability to possess nigh-perfect magical defense. The magical variation of Imperceptibility.

Also Called

 * Magic Defense
 * Defensive Mysticism

Capabilities
The user is capable of utilizing an Ancient Magic that they keep inside their soul. Users of this magic are known as Secret Keepers. The Secret Keepers can place a defensive form of magic in an area or in themselves which makes them virtually untraceable.

Once the spell has been made, the only way for another individual to learn of its whereabouts is if the secret keeper tells them of their own free will.

Limitations

 * The user may spill the secret if enough torture has been used.

Trivia

 * The people who the Secret Keeper has already divulged the information to (secondary Keepers) would not be able to pass it along even if they wanted to and the information in question can not be learned even by stumbling across it, even if one were staring the secret in the face. For example, if someone were to hide a location in this way, even if a person were to stumble into the specific area they would not be able to recognize it for what it was (i.e. as the area they were looking for) and they would not therefore learn the location accidentally.
 * The method for the primary Keeper to voluntarily tell another person the secret can be verbal or written. It is also possible that primary Keepers can reveal information to another by showing it to them.
