I learned a bunch of stuff from talking with the ghosts today; Like that Mastermind is always called M! Well, okay, that's not important, but still! Anyway, we can get the book and keys now, so yay for that! The key's we can find lying around somewhere probably, but the book we need is hidden in the library by a puzzle, so that'll be harder to find.

Once we find the keys though, we can prepare the ritual in advance. At the ends of the boundaries there are these spikes of rock and some other marks at set intervals and the keys just need to be put on those points in whatever order.
Speaking of the ritual, it needs a person of strong spiritual power to cast it after we finish the trial. One of us has enough according to the ghost, they didn't say who though.

I learned some other not as important stuff like that Only the dead who arn't from the current round can use the tower to talk to us and that the town's mana is really low. Also that the final trial's always been an thing with specifically four in every game and that the staircase in the inn that leads down isn't important to the ritual.

Oh yeah! I asked if anyone wanted me to pass on any messages or something, and the ghost said that Zack wants Mia to assist in reviving everyone and that he can 'chip in' incentive if she needs it.

Aaaand that's all I learned for now! I'll post another of these after I finish looking around the church! Investigation, ho!
