The Museum of Freerdonia At Night
The Museum of Freerdonia held a wide variety of books, rep cookies, and relics from various locations and people. You could receive a copy of any of the books from 1posa1 if you wanted to, and were willing to pay. It is, of course, located in Freerdonia.
This museum was griefed extensively in the spring of 2019, and has not been repaired since due to the owner, 1posa1, being banned before chunk rollbacks were made viable again. Many of the artefacts it held can be found in other collections, but some are now lost to the ages.
