That is rather clearly not the case. F/SF takes place in an alternate reality (it's canon, but only within the context of the multiverse) where the Grail was copied/stolen during the Third War. The absence of mention in every other F/SN game of this happening is in its self damning for the claim that its occurring in the same reality as the F/SN grail history, as that's a rather significant event. Besides, there is a precedent for it to be an alternate reality from the F/SN games, which are in themselves splintered. The 'what if' scenario, F/SF has no reason to be the exception from it.

I'm interested.
