Taking it a face value, it certainly is painful to read before finding the energy to type out a sigh and forge ahead in the endeavor to take the wind out of one's sails, but I'm less interested in connecting the worlds, so much as FURTHER celebrating them.

In spite of official quotes given thus far, I merely nod to the probability of seeing remnants of the past in future events and expansions. If the crystal tower were EXACTLY the same one found in FF3, I'd posture the probability of the world being the same as well, but I'm not. I just like the idea of further chunks of other worlds being mirrored in Eorzea, or glimpsed in the Void.

And I think it wise to contue calling it the Void until we go there in the next Tower dungeon to discover otherwise.
