It's not official / cannon, but...
Four-and-a-half years ago, I made a joke in another IQ thread that there was a "special" ending to QFI which gave a preview of QFI2. I even provided a summary for everyone who couldn't find it in the game -- which was everyone, because it's not there. It was all just nonsense I made up to tease my fellow QFI fans.
I still believe it has the feel of how a QFI2 sequel
might start...
