The hero returns.

I don't understand the problem with the elves' activity: in the first version of my playthrough, when I entered the dungeon through the "far" entrance from the beginning and, accordingly, prolonged the time, the elves happily started coming to my castle in the dungeon. Consequently, in the second playthrough, the elves appeared in the dungeon (capturing mines near the castle) around the 3rd week, but then I cut off their supply lines. So, for the AI, their activity seems normal...
