The Primordial Beast of Gluttony has situated itself in the heart of the northern continent. It has managed to incite all of the beasts in the northern continent using its power. All of the monsters in the northern continent have become more active as a result. This made all of the settlements in the northern continent become dangerous as the monsters will ravage them if they show a moment's weakness.
The monsters became more aggressive as a result of their hunger becoming its peak. The monsters would even eat anything they can get their mouth on. The carnivorous monsters became omnivores, and the herbivorous monsters became carnivores as a result. The northern continent is not a place where food is always present and the viable option for most of them is preservation.
