No, I was referring to the (Sky SC major spoiler) Aureole incident and the Orbal Shutdown. It's referenced early in the game, and later as well, but is vague enough to not realize the impact.
Uh... what? There is absolutely zero way anyone could possibly miss it. It's an important part of the plot. This is about Prince Olivert right? That's what I was referring to.
Anyway, it's fairly early on as I recall. Don't remember time in hours.
As for the spoiler you wrote, that's a big one where I think enjoyment is maximized playing the Sky series first. But maybe it's also enjoyable to get spoiled in reverse.
