, but, there was still a closed door (to the right of the tall drop) that I never opened.

Anyone manage to see what was over there?

( I don’t know how to do the spoiler tag so I put what I tried below

you can use the fire word on those dish looking things. They are braziers or something and symbols appear on the posts, corresponding to the words. Presumably this is the code for the final door but I have no idea how.
Tried sequentially in descending order (don’t think I tried ascending though?) and some other things like trying each post as a X is before Y logic puzzle thing.
Yeah mystery dooorrr
