The only thing that bothered and troubled the village head was the annual Magic Beast rampage that lasted several months.
From a safety perspective, most mercenaries will not venture into the forest during this time unless they are really short of money, or they have ulterior motives.
Furthermore, during the Magic Beast rampage, there aren't enough safe assignments available for ordinary mercenaries.
Without work means no income, so during this time, the village head always hangs around the mercenary camps, casting cold glances at these fellows.
If these scoundrels aren't working, they might be better off dead, or just start fighting each other.
If such a situation arises, he will not hesitate to lock up all these troublemakers for disturbing public order, which is not something he's doing for the first or second time.
If they want him to release them, those mercenary leaders will have to dutifully pay a hefty fine, otherwise, they'll have a hard time in prison.
