Some wild speculation about a certain macguffin from 7.0

Well, if you follow the theory that we are actually Azem, because we travel back in time during an expansion, and meet Venat at that campfire, then the key makes a lot of sense. We make it because we need it in the future.

Edit:
Or more likely Venat and our ancient frenemies make it for us - along with maybe a Catboy scientist/adventurer/philosopher with red hair who seems suspiciously familiar.

But the thing is, 'just becoming Azem again' kinda goes against everything that's being explored in Dawntrail -- especially in 7.2. The Warrior of Light carries the legacy of Azem, but they will never become Azem again. They are their own person. Which gave me the idea that The Key could be a warning, an unresolved burden from Azem, not a gift.

Also, very few of our characters resemble Azem physically. Hyur and elezen do, but for everyone else... well, Ancients don't have cat tails.

So sure, you can fit this mystery into that theory, but it doesn't stop that theory from falling apart or being directly against the themes of the game in literally every other respect.
