Kudos for giving us a truly unique setting! I love exploring the less obvious, but no less mystical locations such as a salt flat. The maps have a lot of character, and I'm loving it. Good job with the perspective on them too (that's my weakness). Feedback for your consideration: Because you present such a unique location and story, I would offer a few examples of hooks to get existing parties started on the path to the flats, and have them learn the information gradually rather than having the buy-in all at once. Additionally, as others have noted, I would rearrange things like "Factions, Rumors, and Magic Items (consider adding this title)" to the front of the booklet. This might give the reader a better sense of what they can expect at first glance. Either way, I enjoyed the read. Well done!
