The Museum of Mushroom History is a small building located in the northeast corner of the Marketplace. It is run by the Curator, and features an unknown number of artifacts and displays. One known exhibit is the Clovis Arrow, retrieved by the heroes in Chapter 3. Other possible exhibits include an area on naval history, as the Curator will purchase any anchors found by the heroes in Chapter 5, and an area on Outland Stronghold, if the heroes give him the map they find in Chapter 10.
The museum is also known to have a vast collection of books and other historical documents, as the Curator searched through many of them in order to locate the ore pieces.
