Stuck need some kind of hint, late game
​
So I've got all the letters, >!found room 46 and the sanctum, opened plenty of doors but only solved the first 2.!< I used the >!monk's blessing!< to draft >!the antechamber!< outside because of the clue in >!ladyships chamber.!< it really didn't help much. Have the >!black bridge connection!< and found the area >!above the sanctum!< and the >!train station!<
Even doing the >!class 9 exam!< and having read all the books i can access, I'm unsure what the move even is from here, what im supposed to do to find the >!sigils!< or hints towards them. Or any forwards game movement really- the mail room letters seem very basic so far, and i am stuck in the >!tunnel outside ar that blue crown door.!<
