Ok, I give up! (well, at least I am going to ask while I keep looking!) I am in the Catacombs of the Kings, and have found the key in the upper left, for the mirror, and I foud a key in the lower left I used on a door. I can't find a key for the Din's Fire chest. Any hints??

from left to right in the fifth row 3th screen from above and third screen from the bottom have a key 😉
Thanks, Elise, thought I had tried that before, but...
