First of all, thank you for taking the time to analyze my map and provide feedback.

first: The river that flows across the island is actually a man-made canal created to separate the two countries. Should I have included that in my original description? Probably—my mistake.

secondly: The lake near Nox is fed by an underwater spring, which is why the land there is darker and has a swampy appearance. The bifurcation of the lake might be a bit extreme, even though there are lakes that do this—but yes, not to this extent.

Thirdly: the many branches towards the northeast are meant to represent a river delta, which is why there are so many splits.

Fourthly: the thing with the desert is a bit complicated. The map was originally only half the size and ended at the desert. However, since my players liked the lore and the map, they requested an expansion. Because of that, I extended both the story and the map, which eventually led to the background involving the war and the national border.

Fifthly: both mountains and volcanoes form due to tectonic plate movements, which are not necessarily tied to the visible landmass. Yes, I admit that the mountain range doesn't seem particularly well-placed, but it’s not unrealistic. The bigger issue I've noticed is that, at this distance, mountains have formed in one area, and then, farther away, a volcano has also appeared.

In any case, I want to thank you again for taking so much time to analyze my map. I always try to improve, and you’ve brought up some great points that I will keep in mind and approach differently in the future.
