Picking up the map that I created that maps out the area around here that is the main focus of the Expedition quest, I have to track down the villages of the scourge, the villages that have the same fate as the first village. It was called Village of the Scourge due to how it turned into an area where only the scourge thrives and the monsters that like living there.
I don't know if there are changes that are added or removed but there are at least 6 more villages left to destroy before the scourge and the monsters will invade the whole Luminous continent. Because the monsters are quick to spawn, if they are left to their own devices, the villages will get overwhelmed by monsters and the monsters will soon spread the scourge and envelope the whole land with it.
