Thanks to Schwahn for the inspiration!

Final Fantasy XV had a lot of speculation surrounding it, while it was in development. Once the game came out, we had more questions than answers. Only, not in a good sense. We had questions like “what did they cut?” rather than “what did it mean?” for the most part. The game felt incomplete.

This was a post on Reddit which asked for thoughts about a certain fan theory:

Greetings,

Quick heads up – Spoilers (For XV, Brotherhood, and Kingsglaive)

So, an interesting theory has come to mind regarding the world of Final Fantasy XV.

In Kingsglaive we see two very definitive creatures from other Final Fantasy universes.

Diamond Weapon – Final Fantasy VII

Ultros – Final Fantasy VI

Final Fantasy Peasant did a video on this same topic. The octopus in Kingsglaive: Final Fantasy XV is nameless, but fans could recognize that womanizing cephalopod from anywhere.

It was Ultros or at least a homage to him. Why else was he trying to steal Luna? But why was he in the movie? And the monster at the end? It was Diamond Weapon, from Final Fantasy VII. But what did it mean?

Now, this can easily be written off as just fan service and we move on with our lives. But, let’s ignore that idea and take it further.

Another user spoiled some things about XV in the title of their post, which has been thankfully taken down. Appreciate you /u/fforde

From this, we also know that Doomtrain from Final Fantasy VIII is in the game as well.

Unfortunately, this isn’t true. Doomtrain was in a promotional picture for Final Fantasy XV, but sadly enough he as an entity wasn’t. A long stretch of the game involved Noctis and his bros riding a train to their destination. This train is also not Doomtrain. It would have been an interesting parallel. How awesome would it have been to fight the summon much like we did in Final Fantasy VI with the Phantom Train. This was just a missed connection.

In the first episode of Final Fantasy XV: Brotherhood – we see a Merilith – which most notably is One of the 4 fiends of Chaos from Final Fantasy I

And that’s the only time we see her. Even I thought Brotherhood: Final Fantasy XV referenced this scene from the game. Instead, she was exclusive to the anime; we don’t battle her. How cool would it have been to fight her? How cool would it have been to fight the other three fiends? Another missed opportunity from the director who claims Final Fantasy I was his favorite.

They just keep going, which got me thinking.

We know from Type-0 being Gilgamesh’s “Origin” story that all of the Gilgamesh we see in all the games is the SAME guy. They are all him.

He is traveling the realms and appears in multiple Final Fantasy games. This tells us, that even though each Final Fantasy is separate, there is SOMETHING that links them together.

We can call it leylines or wormholes or whatever you want. There is some link or ties that bind the different realms and universes of Final Fantasy together.

We now know of 4 of these big iconic creatures from different Final Fantasy games that are appearing in Final Fantasy XV.

What if Niffelheim (The Evil Empire) has found a way to open up said leylines/wormholes and is traveling to other FF worlds and is capturing “Daemons” from other worlds to help them in their conquest.

Just use some magical machinery, open up a door, go inside, capture the first “Big Beastie” you can and bring it back with you to be a powerful piece in your war.

Thanks for reading and I would love to hear/discuss your thoughts on it.

You know what’s really interesting? Gilgamesh was the only character who appeared in Final Fantasy XV’s gameplay. We assume it was through the inter-dimensional rift. But for whatever reason, this Gilgamesh doesn’t act like the Gilgamesh we all know and love. Is it the same Gilgamesh? I still think so, but I don’t know why…

What if Niflheim accessed a wormhole to capture Daemons? In fact, that would be pretty cool. Instead, we don’t even get an arc from Verstael Besithia, the head scientist, until Episode Prompto. We don’t really know much of what’s going on or who these things are. Ultros dies in Kingsglaive: Final Fantasy XV, I guess. He falls and we never see him again. Diamond Weapon isn’t spoken about in Final Fantasy XV either. It’s all very strange. But now, we don’t question what was their connection. We wonder: what happened?
