Looking for late game hint
I am at what i think is the last major puzzle i have not solved (of course, there might be more pending on what I discover when I solve this one).
WARNING: DISCUSSION OF MAJOR LATE GAME SPOILERS BELOW
I have found >!the secret tomb that mentions "the Black Key". I've solved all the puzzle boxes in the room and figured out how to make the clock on the tomb appear. I believe all I have to do now is figure out what time or combination of times I need to press on to make something happen!<
For now, my question is >!am I correct that the odd message in the clock tower that mentions directions and "dark is the day coming fourth" is key to figuring out this puzzle!< ?
Thanks!
