Discrepancy in lore (spoilers)

[Hank_Hotspur]

Have you not played other Final Fantasy games? Completely anachronistic settings is how they roll. Most FF games from VII onwards have swords, modern-looking cars, traditional magic casting, and spaceships.

Even the original NES release of the first Final Fantasy game had the Floating Castle map designed to look more like a low orbit space station. Which makes sense, because the first FF game was basically a D&D video game with the copyright filed off (and some copyright not filed off until the later rereleases) and at that point classic D&D loved to have high fantasy inexplicably meet super science or extraterrestrial tech like in the Expedition to the Barrier Peaks or Temple of the Frog modules.

Even after they changed the sprites in the Floating Castle to make it look more fantasy, they still have these warmechs walking around.
