More seriously, this is the kind of thing you don't want to spoil, so reviewing early seems reasonable. I can't really spoil anything because I don't know much of anything yet anyway.
The fact that I'm caring about spoilers should say something. Normally, I don't care, but this is one of those times where it feels like it matters. Not necessarily for the plot, but because of the setting.
Yes, the setting. Numenera is a weird place. It's a bajillion years in the future, in the so-called "Ninth World". Each "world" is like an era of mankind. Mankind rises and then falls and then a new "world" happens. From our 21st century perspective, we might be on the second or third world now, right? Fall of Rome, World Wars one and two? Something like that? Nope. We may not even be the first world yet.
Yeah, we're talking huge gulfs of time here.
