Thank you for your comment. The information was put here first to establish the structure of the world as you said. So that further story won't have any conflicting ideas or perspective. Future revision might remove or decrease this chapter info.
Itachi_Hyoudou:He is writing the structure of the world. Although you and even I dont like such info dumps but it is rather important because it's not an established world. Its not a fanfic that's world setting already know by us. it's an original and we know nothing about the world setting. Though he could have implemented about the information about the world through sharing some info here and there instead of just dumping it all in these two chapters.
