Iβm not sure if anyone else is interested, but I started making a map of all of the places mentioned in the book, with filters by chapter. 
I have a general key that may change in the future:
- Default blue pin: place that is mentioned but was not visited in the chapter
- Green camera icon: place that has been visited in the chapter
- Red question mark icon: place that may or may not exist, that Iβve mapped to something that seems like it could be correct based on context
Please be warned that Iβm not sure how the link will open (filtered to the first chapter or with all chapters open), so there may be an initial risk of spoilers. I opened from another browser, and it looks like it sets the filter to the first chapter, but better safe than sorry.
If I missed anything or anyone else wants edit privileges, please let me know.
