This is story related and cannot be missed.
You will get this after completing either one of the two temples later on in the game.
Which one you tackle first is up to you. Personally I found the Scabanian temple to be slightly more difficult, but this is just me of course
In the temples you have to solve several rooms to proceed to the final chamber.
In these rooms you always have to find a "bell song", light a fire and then ring the bell to solve the puzzle of the room.
You will know that you have completed the room when you exit the room and the door closes behind you.
If you need any help in the temples refer to the videos below: (video credit: PS4Trophies)
Hope this helps you guys
