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 File". Should a look of pain and worry come over the face of the worker, you will be taken deep within the facility. Should the item feel cold, however, voice one question aloud into the cell and pull back your hand. The only question to receive an answer will be, "Which side are they on?" That file is Object 54 of 538. It will smooth your way to the reunion, but cannot help you from there beyond.
