Yes, and another bug. In the current version of the map, it seems that you can't cross to the shore near Udaje without flight or teleportation. Ideally, a boat is needed, but the boat doesn't deploy heroes there. There is free space, but it still doesn't work. I think it's probably blocked by invisible "events," which is illogical, and I didn't even suspect that was possible. But now I know.
Events and pits affect the disembarkation from the boat onto the shore, i.e., if they are present on the shore, the hero will not be able to disembark. This is a feature, and I often use it. Take a look at the HALO map near the Necropolis at 2x37x0 - in the game, the blue hero cannot return home - I immediately placed a pit and an event there.
Regarding the mythology and texts on your map: it's all very beautiful and stylish! I got engrossed in reading it!
I don't have time to test it yet; I have several unfinished maps of my own...
