The names of the water and landforms all come from the in-game Encyclopedia. I understand that since the game is still in Early Access some these names or their locations are likely to change as time goes on. Also there was a lot of inconsistency in the Encyclopedia when it came to spellings. For example the name of the desert Nahasa has been spelled "Nahhas", or the Aminys River was once spelled as "Amnyis," little typos for proper nouns so my rule of thumb was to use the spelling that we see the most of in the Encyclopedia (tempering that with a bit a common sense).
The terms Lysian Strait and Garontor Promotory are not in the encyclopedia, but the village of Lysia's entry says the village's name was applied to the nearby strait and the Garontor entry said the village's name was given to the promotory. I figured those things needed names so I might as well apply them.
Let me know if you think something is not correct, you have a suggestion, or you have a question. I'm new to creating maps like this, but I saw no one had done a compilation like this so I thought I might as well make the attempt.
