For whatever reason I’ve seen people say they don’t consider The Lost Metal a critical part of the second arc (maybe because it happens or was written a few years later?). I would disagree wholeheartedly and think it makes the series. It’s what finally pulls the second era to a comparable level to the first era for me.
The percentage of the population that’s illiterate is way higher than it has any business being.
Like “can’t read at an elementary school level”.
