That happened! At the beginning, he was a nuisance that kept things interesting, so I had to give him my castle for 2 weeks to gather my army and finally defeat him! It was interesting, especially during his first four appearances.
But towards the end, it became annoying to have to chase him every month (although with upgraded logistics and boots, my movement range was about one and a half times greater, and I could easily catch up!).
It would be nice if there was a quest at the end of the game to get rid of him!
That's a good idea, I'll think about it. In principle, it could be done so that he appears less and less frequently each time, or so that he no longer appears after capturing the Inferno castle. But the castle can be captured quickly.
