In any city, in any country, go to any mental institution or halfway house you can get yourself to. When you reach the front desk, ask to visit someone who calls himself "The Holder of the Path.

 Approach it and ask one question: "How did they acquire guardians?"

The Holder of the Path will never go into detail about itself.

That is Object 7 of 538. Its Holder will do anything to keep you away from it.
