I was confused as hell and then I realized you were talking about a different series.
Yeah, Dune series is insane. Tho, only God Emperor got that absurd time jump (3500 years with the prequel and 1500 years with the sequel). The other parts only got a few decades at most in between.
The games Nier Replicant and Nier Automata got about nine thousand years between each other.
I happened to have put together a class curriculum for something quite similar when I was doing volunteering work at FreeGeek. This was a few years ago, but it should still be good.
I second this!
