So i recently finished a reading of Xenogears Perfect Works, which has a ton of content, especially a timeline detailing the events of Xenogears Episodes 1 through 4 (as these never became games and probably never will), as well as more expanded details on Episode 5, which is the game itself. But despite all the new things i learned regarding Xenogears lore (and i'm gonna have to give it a second read because even though i understand it better, Xenogears lore is really complex no matter how you look at it), there's one thing that i didn't find any answers for: what is Xenogears Episode 6? The only bit of info that Perfect Works has about Episode 6 is that it's the last Episode of the Xenogears timeline. I'm having a hard time imagining what Episode 6 would be like, given that Episode 5 had a pretty natural ending. I can kinda come up with some scenarios but only one of them seems plausible.
Scenario 1
Scenario 2
Scenario 3
I also wonder if Fei and Elly would've played a part in Episode 6.
Any ideas?
