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 Map". The man or woman will not look up from their reading materials; memorize the page number.
Repeat yourself firmly. The man or woman will look up, annoyed. They will make a snide comment. If you hear, "Another moron", you will have found the right place. If there is any other comment, he will lie to you.
The man will then start by giving you directions. You will not be able to write them down, no matter how hard you try. If you don't follow the directions exactly, you will get lost.
You will find yourself outside the institution; this will be the worst fate you could imagine. If you follow the directions, you should hear a sound as if an infinite number of hands are writing. This sound will increase as you near your goal.
Should this ever stop, breathe deep and yell any information you have about where you started at, including your directions on how to get there. The writing should start up again. If it didn't, you will have to go back to where you began and start again. Don't get lost.
At the end of the directions you should see a door with an electronic lock, the numbers stained with blood. Stop immediately and you will hear a giggle. Don't turn around. A voice will start speaking under the now deafening sound of quills on paper. Ignore it and whisper one question: "Where will I end up?"
He will go into grotesque detail about an ancient battlefield. At the point when he stops talking, input the number of the page the receptionist was reading from. You will wake up in the nearest church to the institution. You will be lying on a map.
The Map is Object 70 of 538. It will guide you anywhere you need to go, but not to the location of the other pieces.
