Prevent Monster Invasion in Ch2 *mild spoilers*

In Ch.3 (edit: not troll trouble), needless to say, monsters invade. Without spoiling anything, these creatures deplete Kingdom stats severely. Is there any way to avoid this or is this story related? I thought the game said I had 200 some-odd days before the next attack!

It’s either because you are doing the main quest of the chapter too slowly or you haven’t cleared Bald hilltop of the monsters. That last part about Bald hilltop need to be done at the end of every chapters.

Chapter 2 Troll Trouble? some guide call it ch.1…

If yes then, its most likely that you need to find the Trolls lair before they completely destroy your kingdom.
