X, I've actually read both novels 100%. I know full well what the far side is, in the future, please do not talk down to me.
Lantz, I think she meant the fanfic Fate/Far Side, though I could be wrong.
No, I'm pretty sure she meant the Far Side of Tsukihime....
Ilya cannot save herself even with that knock-off of 3rd Magic, otherwise, she would have done it to survive.
Nasu is very clear on that she dies year after Fate or HF Normal.
Where is he clear on that? And, no, Ilya talking to Zouken mid-route (or whatever) doesn't count, because Ilya is not omniscient and she's not Nasu. I mean a
specific statement from Nasu that states or at least strongly hints that she will not survive.
In the Hot Springs episode you get if you get all of the endings, Ilya is asked if she has a way to survive, and the answer is "maybe", in a way that definitely implies she does. I don't see anything from Nasu that has ever said conclusively that Ilya will die post-Fate.
