The Forest Sea and the Red Earth Forest are centrally located on the continent, adjacent to tropical regions. Further north lies the forbidden land, where human civilization has hardly ever set foot.
However, there is a well-developed map, derived from the knowledge gained by unlocking the levels of the Pyramid and from the explorations of human sages.
Since humans first set foot in the mining area, it has been in the temperate zone of the Southern Hemisphere. Even after hundreds of years, humanity's mining bases at their various strongholds are still near these regions, due to climatic reasons.
North of the Forest Sea is collectively known as the Northern Region. Correspondingly, south of the Amara Continent in the Southern Hemisphere is known as the Southern Region.
Thus, the range of human activity is actually very small, fitting snugly in the world's crevices, much like their place in the real world.
