I got FFXI vibes from this new ff7r ancients trailer.
I know all the games have somewhat similar backgrounds but still.
Part of modern Final Fantasy is shout outs to the other entries, even the less popular ones.
This and Esdain's correction got me thinking a little bit.
The Kuluu destroyed the crag at Vahzl in order to stop the Zilart from opening the gates of paradise.
There are telepoint crystals at each of the crags, but also on Zepwell island(Altepa) and Elshimo(Yhoat). Zepwell hosts the Dawn Maidens' Zilart hologram device. Elshimo has the last Kuluu temple, Uggalepih, where the Kuluu mutated into tonberries due to The Meltdown pouring out magical radiation all over Vana'diel.
But then you know, we meet Nag'molada in CoP, and I haven't gotten through my replay of it yet, but he's a Kuluu too or something. I guess not all the Kuluu rebelled and some got to be in stasis with the Zilart? Hmm.
