019 W of Tower Courtyard: Look in the basement of an old building for a Document.
020 Far W of Tower Courtyard: Farther West from the Document above, you find a Coin Cache. It’s in a very bendy section of the lower tunnels.
021 Far NW of Tower Courtyard: A long stretch of cliffs leads to the map’s exit. Look in the bushes at the southern end of that final stretch of land to find a Document.

023 E of Tower Courtyard: A Document is only a few feet away from the camp.
