Your feedbacks will be checked by our staffs and will be attended to accordingly. Please be advised that we may not reply to every individual feedbacks.
400 days ago people already talk about this place lol
So.. The Chasm is part of Sumeru?
please those who are saying its not a region go check the map which leaked previously after all it will introduce the dendro element and the region is in the exact location show using your Grammer in this
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
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.
