Answer to the question below me:

Because it is stated in many npc's dialogue that the chasm is a mining location of liyue. But it's closed for now since there are many accidents and strange thing happens

Anonymous 5

I always thought the chasm was what they called space. like those black parts of the map is called the chasm. what made you guys think it is an actual place? did mihoyo ever said something about it? because chasm is the synonym of void.
