I did find the history of the gunslinger interesting. How this particular gunslinger came to be anyway. I can't speak for some of the others. So, apparently, there is only one teacher for boys to become gunslingers. If they fail to become a gunslinger, they are dead, and the family line of gunslingers ends. Obviously, this will eventually lead to one last gunslinger, and this book is taking place during that time.
