Like Final Fantasy VIII, Final Fantasy XV will have the same type of theory most media have: it was all just a dream.
- The whole road trip is a ten years long dream. Brotherhood and everything else you experience up to Chapter 13 was Noctis dreaming inside of the crystal. What we saw was the dream version of the original quest. We could probably make a ton of assumptions of the real events. Maybe it was similar to Final Fantasy Versus XIII?
Since Final Fantasy XV originally had a sleep theme, this is possible. This theory has a Final Fantasy VIII vibe to it. But, due to the relatively unfinished and vague storyline, others exist:
- Noctis’ world was supposed to be the new world at the end of Lightning Returns. When Final Fantasy XV was Final Fantasy Versus XIII, it connected to the mythos of Final Fantasy XIII. But how? At the end of Lightning Returns: Final Fantasy XIII a new world is created:
The new world resembles Earth with its continents mirroring those of the real world, and the town seen during the epilogue FMV features modern buildings, roads and cars, a modern train and a train station, and there is a plane in the sky that creates a contrail.
Surprisingly enough, this world looks like modern-day Italy and Japan. But is it Italy and Japan, or is it the beginnings of Altissia and Insomnia?
- Every other Final Fantasy is simply a game in Eos. Two good pieces of evidence for this: Prompto’s very specific victory fanfare and the music played in the Regelia. Maybe Eos’ favourite musical style is midi chiptunes, but I doubt it. The “fantasy based on reality” reinterprets the Final Fantasy games as based on their world. Ivalice is also a book series that Gladio reads, but he can’t get past the first page…*
- Noctis awakens in another Final Fantasy world after death. Eos’ afterlife is an alternative universe, but what’s to say that it can’t be another Final Fantasy world? Which one is it? That’s up for debate. My vote is the original Final Fantasy. A thousand years ago, the Western Keep was probably the Lucis Kingdom. The Warriors of Light travels to stop Garland at the Chaos Shrine could coincide with Noctis’ arrival. The Lucis Kingdom is to “the West” (i.e. “Western Keep”, after thousands of years). Titan and Bahamut reside in this world. Perhaps Astros, the evil elf, is an Astral?
- Cor is an Astral (either Ifrit or Bahamut). I strongly believe Nyx got the development Cor should have. But Cor as an Astral would have been a pretty big twist. His name translates to “heart of the lion” which reminds me of the fire symbol Leo. Cor is a type of aid to Noctis. Gentiana is Shiva, and also a type of aid to the Luna. Plus, what’s with the kiss Shiva gives Ifrit at the end of the game? Cor is 42, an unlucky age in Japanese superstition. Would Gentiana, an “old flame”, defeat him? I bet you’d ship it. You know you would. I do.
There’s more, so who knows what we’ll see in the future.
*Gladio doesn’t turn the pages in his book to avoid cultural confusion. In the West, we read from left to right. In the East, they read from right to left. They don’t want him to turn the pages from either side. Fans think Gladio is either stupid, can’t concentrate or can’t read.
