While I'm extremely excited about all of 7.2, I feel like the Occult Crescent is the stuff that's REALLY throwing out the hooks for the proper long-term Lore Nerds, so I felt like it might be good to have a thread for this!
So, first of all, a bit of a collation of details I've gathered from the special site and the live letters:
- The actual landscape includes buildings that clearly match Nym, Mhach, and Amdapor's architectures.
- Accordingly, its music is actually a medley of their dungeon/raid themes: A Tonberry's Tears, The Scars of Battle, and Teardrops in the Rain. But interestingly, there's another inclusion in it: Far From Home, which is Skalla's theme, the unlucky fourth victim of the War of the Magi. I haven't seen architecture I'd call Skallic, but that might be because of inexperience.
- The 'Phantom Jobs' we get in the Occult Crescent are a mix of jobs we do and don't have; in the first live letter Yoshi-P actually talked about how some of these jobs might not be viable to make as full jobs (they've tried to crack Chemist at least twice before), so this is a chance to play in the space without hitting that problem.
- In the second live letter Yoshi-P mentioned the Phantoms Jobs of jobs we do have, like Monk, are ancient forms of the job. So by logic, the other Phantom Jobs like Time Mage are jobs that did exist, but got lost over time.
- The end raid instance of the first Occult Crescent zone is the Forked Tower; from the screenshots it's a little hard to tell if it's Nymian, Amdapori, or possibly both, but I feel like I can comfortably rule out Mhach. Fights that look to take place inside seem to include both some Demon Wall-looking figures, and a Sin Eater-looking guy.
- All of the outside-XIV inspirations that have been mentioned for this, including the Phantom Job icons, are from Final Fantasy V.
- It's a Ketenramm story, and there's a scene of him opening some kind of stone chest or coffin with us, possibly inside Forked Tower. Sure enough, FFV's Forked Tower did have treasures at the end of it: the ultimate Black and White Magics, Flare and Holy.
So with all of that, my own theory on this one:
The Occult Crescent is from the Fifth Astral Era, and got unstuck in time somehow; this lines up with FFV's city of Mirage. In FFV's story, the world got split into two a thousand years ago, and the city of Mirage was stuck in a weird state of flux that froze it until the worlds got re-fused. The Occult Crescent probably isn't exactly that, though, because that'd cause VERY odd questions regarding shards and Rejoinings.
All these locations are very close together and by all appearances intact; Nym's corner looks a little waterlogged, but that's it. This makes me feel like it might be from before the war; I can't imagine these three (four?) would all be neighbors without blowing each other to bits during the war. We don't actually know the inciting incident of the War of the Magi; maybe this joint colony disappeared and everyone blamed each other?
