Personalities and characteristics... (Skippable)
Well, I know it's late to do it now, but let's do it anyway. It can reduce some confusion at least. I am introducing this now because all the characters were not introduced during the early chapters and it would have also ruined the suspense. So, I hope you will forgive this poor author.
