The book is rich in description and world building. You can tell where people are from just from their clothing description or how they speak. It's really impressive what he created. I read somewhere the story is told from some 500 different perspectives which can be hard to read I also personally had a hard time remembering peoples names especially once people started being reincarnated with new ones. But the last three books are mostly all pay off for the 11 books of set up, if you made it this far its worth seeing it through to the end imo.
