Æsop, the Ancient Greek (or possibly Persian) person who is famous for writing "Fables," is quoted as having said:
"For every fine cat, a very fine rat"
Every hero needs a villain; if they kill the villain, they have to find a new one (son of villain!) to fight, or the story is over.
You can't kill off a good villain until you have a proper replacement.

Is it just me, or do none of these maps make any fucking sense at all?!
Every time I see a map, shit has changed; from the position of mountain ranges, to the orientation of North, the maps are almost entirely unintelligible... which is honestly super weird, as most authors (and Japanese society as a whole... well, and me) kinda have a bit of a map fetish; super weird to have such a randomly shitty set of maps.
