UPDATE: The map is finally done. Here are the links for the things and how to put them in your game.
The Civilization folders:
Put these in Program Files > Steam > steamapps > common > Age of Civilizations II > game > civlization_editor
The actual map:
Put this in Program Files > Steam > steamapps > common > Age of Civilizations II > maps
Also, in that location, there is a JSON file called Age_Of_Civilizations.
In that JSON file, you can see that it contains all of the Map folders.
You will need to do the same with the Elder Scrolls map;
