SpoilerDoes kind of make you wonder what happens when he dies of old age. Does one of the former maidens survive as his widow, become the new Oba, initiate and train a new group of maidens? Who then wait for his reincarnation to grow to be a young man and appear once again?
Yeah, you're right, and frankly it's not just those questions, there's a lot of them that are going to remain unanswered from throughout the story. It's not that I personally find it a major deal or some kind of a let-down or anything.....but yeah, there are lots of things that will now remain unexplained.
