Oh, good. That was kind of the most optimistic possible guess she had for exactly how protected she was here, exactly how powerful that whole metanarrative protection was. Because, like, you can totally imagine something that looks like what she's gone through thus far where, like, she's in a simulation of some sort and an AI with only so much attention on her nabbed a universe out of her memories and kind of half-spun-it-up while only paying so much attention and in the spinning included the fact that Tzeentch is totally the sort of bastard to notice if his universe's substrate changes, resulting in Sneaky Tzeentch Of Sneakiness. And, like, probably that doesn't go too badly for her but she's not sure it goes no badly. But fortunately she is instead dealing with something with rather fewer holes than that.
Okay, I think I am officially no longer worried.
Provided the notebook is telling the truth. Which she guesses it is. But she's just going to keep tracking the possibility that its not. Just In Case.
Actually, a related but distinct question. I just noticed I'd been, uh, assuming that by virtue of being a Magical Notebook I didn't need to worry about, like, the building being on fire causing Notebook Problems. Is that actually, uh, true?
She really should have asked that during her day of preparation work.
