Here is the map of the Inner Sea. This is the culmination of many individual maps, produced over many years, collected together.
This is a very low-res version of the full map, which can be found in more detail here, but it is searchable - just click on a part of the map and you should be taken to a more detailed map for that region.
I am working on getting the links to direct to a small bio page for each nation, but all in due course! Please let me know what you think :)
