I have been wondering recently about the thing that Square Enix is planning to release a fourth game, titled Haeresis, in the Fabula Nova Crystallis compilation. That got me into thinking what this game might possibly contain. Considering the fact that the three games that we have got each focus on an unrelated story with different characters in apparently different worlds in the same shared universe, my theory is that this fourth game somehow bridges the three games together and thus, we for example get to see Noctis and Lightning meeting each other and thinks like that. What do you say about this theory, I would be interested to know.
