Here's the deal with the location names, straight from Wallace himself:
Location names - I've seen a few comments complaining about the 'made-up' names on the map. This is an interesting case of where you can be criticised for something you are not actually guilty of. I did not want to make up random 'fantasy' names, as they can all sound so similar. All of the names on the board are real words, taken from the Penguin dictionary of Curious and Interesting Words. 'Fadge' means a bundle of leather. I took great care to make sure no word used meant 'penis', of which there were many in the book.
