Or at least, I think it's a typo. Otherwise it's putting Michael Curtis in the running to have "High Curtisian" as a writing style:
"Referees and players looking for complex details on overarching plots and other story elements will not find them here - but that doesn't mean they can be introduced!"
Ah, 't, where are thou?
It's obviously a mistake because the rest of the paragraph is about how Stonehell is just giving you the facts and it's up to you to tie them all together into a narrative whole.
But I laughed out loud and had to backtrack and read that one again.
I make my own share of typos (and even actual outright errors that need fixing.) But rarely are they as funny as that. Maybe Tin Shorts, which I need to stat up as a magic item.
