And thats what they have been doing so far with their references and callbacks from other FF games to fit with FFXIV's lore. And if you played FFIII and understood its lore, then you would've noticed how heavily they borrowed a ton of elements for FFXIV's msq. But I personally never minded it since like I said they reused them well to fit into the setting.
But back to 6.2 speculation, I'm wondering whats the deal with Golbez in FFXIV's setting, since in his game he was just being mind controlled by a powerful Lunarian, Zeromus and wasnt really a bad guy. I wonder if that'll mean anything.
