Temple of Quarn is also one of the few hints thanks to a side story that Emet remembered not only Azem, but also that one time Azem went "I'm going to use Ifrita to save some grapes." As the door puzzle's symbols are The Flames of Magic and the Fruit of Knowledge. I'm sure there's been other nods staring at us in the face about the past that we just don't recognize as hints due to not knowing what to look for.

We just know that symbols of Azem in some shape or slight variation keeps on popping up. One of the reasons why I get mad at both Emet and Elidibus when they get mad at us for forgetting in game history is there'd be more to remember if they weren't destroying parts as collateral damage each time they create a calamity.
