I don't really know how it can be FF7-inspired. We'd need Shinra Inc (which is the Garlean Empire in this game) but we finished them off.

We would need a climate change crisis like in FF7 and real life that is caused by burning fossil fuels. We could argue we are burning too much Ceruleum (which is aether), but it was mostly the garleans doing that I think unless the people in the blue mage story have been using it a lot too. We could argue this aether was being burned another way, by primal summoning, but we already solved that.

It starts to look like we would need to visit another shard to find these circumstances.
