Now I'm stuck at the letters puzzle ;-;
The conological order doesn't seem to be it.
It's kinda unclear and i had to brute force it but the box itself gives us a starting F and ending E, the safe gives a CA somewhere in the middle which makes the word facade
I found this confusing as well because the symbols are hard to see but I think I identified the intended solution
the box tells you first + last letter which leaves only one possible combination.
