Something I found curious was a number of the Voidsent you encounter being identical to/reminiscent of the Kindred from XI. Coupled with the appearance of the Goblins, Qiqirn and Mamool Ja it does lead one to believe that the connection to Vana'diel is more than a bit tenuous. I've read discussions where people theorized that while the different FF worlds are indeed separate, they share the space between - i.e., the Void. It's shown that the boundaries between the Void and physical realm can be messed with, so it's not outside the realm of belief that a cataclysmic event such as Bahamut Megaflaring everything to hell could rip a hole straight through the Void and into another world.
