The Structure of Epic Plains
[AN: I'm making a significant but important change in ranks because many people still don't understand the ranks fully, and it only causes more confusion. I considered changing it for some time but decided to wait until the last volume was over because it would be quite confusing if I changed it in the middle of it. And I can't change it from the start either since it would be problematic for old readers. So, I would like everyone to take this inconvenience with a pinch of salt.]
[Change: I will no longer use the [Type Rank]. It will be changed with the normal ranks of Common, Rare, Extraordinary, etc. But the Basic, Intermediate, and Advanced levels will remain the same but for only materials, technology, knowledge, treasures, and such. The Tiers will be exclusive for power rankings, nothing else.]
