Ivalice raid setting

[Enkidoh]

Vidu is correct - despite all the flavour text the Ivalice raid is not FFXII/FFT's world and places somehow transplanted into Hydaelyn or somehow acts as a sequel/prequel to those games. It is simply using those place names, character names and story elements in a FFXIV context as fanservice, just like how we already have FFIII's final dungeon the Crystal Tower/World of Darkness, FFVII's Costa del Sol and Gold Saucer, FFI's Matoya's Cave, etc, and those places are not the originals either, they're Hydaelyn-specific locations that just happen to have the names of areas, story elements and ideas and even music from earlier FF games for fanservice reasons.

And the final say was the development team themselves already stated this long ago (even before the Ivalice raid was added, but when there was first hints about FFXII locations in Hydaelyn):

1:57:29
Q: A lot of names from Ivalice have been mentioned such as Dalmasca, Belias, and Zodiak. Is there some kind of connection between Hydaelyn and Ivalice?
A: Maehiro: To be absolutely clear, there is no direct connection between FFXIV’s Hydaelyn and FFXII’s Ivalice or even FFXI’s Vana’diel. They are not the same world in different dimensions or time—they are their own separate worlds. However, there are certain connections to people or objects that appear in these other worlds that figure into the story of FFXIV as it has been conceived and is being told.

Yoshida: We’ll be revealing more as we move forward.

So basically, the 'Ivalice', 'Dalmasca' and 'Rabanastre' that exist in Hydaelyn are not the same Ivalice, Dalmasca and Rabanastre from FFXII/FFT, they are completely different places specific to FFXIV that just happen to share the same names, appearance and certain elements for fanservice (and this is hardly the first time SE has done this - this happened as far back as the mid 90s when FFIV had a place called Mysidia which of course is also a place that formerly appeared in FFII, and later on the there was a Mount Koltz sign in FFVII referencing the place from FFVI, FFIX's Mount Gulug referencing the dungeon from FFI, etc).

Hence, don't read too much into it.
