Today I want to talk about something that can happen at the end of a story. Well, it mostly happens at the end of video game stories. It might have happened to you: the final stage has been conquered! The antagonist that you’ve been chasing for days has been defeated! But zounds–what’s this!? A new foe has appeared! Some giant creature that no one ever expected! Some horror that wasn’t even hinted at before or ever explained!
Over at TV Tropes it’s called “Diabolus ex Nihilo.” Or “Giant Space Flea from Nowhere” if you’re talking about a video game.
So let me give you an example from a video game. Of course. Like I’d read a book. Here come spoilers for Final Fantasy IX. (Now out on Steam. Dang, I should have put it on my birthday list.)
