Forest of nightmare was definitely a very dangerous place but the outer region was nothing too serious. This was the area where the ingredients collecting happened, so knights of this nation had already cleared this place out more or less.
As for why this region currently had little to no ingredients, it was simple. This place did not have an infinite amount of resources.
Normally the royal family made sure to only collect only a limited amount of ingredients to make sure more could grow in a short period of time.
But few years ago, a foolish prince had used his authority to collect a huge amount of ingredient from this place in order to create an army of his own that was filled with only official knight rank powerhouses.
The people he had sent for the collecting mission were also stupid and they did not care about the future and looted everything that this place had to offer.
