a hidden event on the water with fairies and azure creatures for useless artifacts
Yes, it used to be useful, and even excessively so. But with SOD_SP, it lost all meaning and appeal.
This is a relic of the past. Whether to remove it or leave it makes no difference. I might come up with something to do with it later. That's why I'm keeping it.
the path to Utopia - it's also useless
Well, here, it's either a hole in the map and a set of empty corridors, or at least something.
Again, a place is reserved for a puzzle. There were ideas about how to develop it, but they turned out to be unworkable, or they were more suitable in other places. So yes, it's useless. But it's better than an empty space.
a set of clues - the troops from them are not needed anywhere
various imps, nagas, and jellyfish on barbarian lands.
Yes, I understand that it's a habit that "you have to take the consulate."
But here, on this map, it's not relevant.
So all these objects are just a variety of the landscape. Otherwise, it would be very monotonous.
--------------------------
I agree with these comments, at least partially. As I said, there isn't much room for creativity on this location. You'll ruin the picture.
And the choice here is: make it monotonous with just a series of labyrinthine paths, or diversify it somehow.
