"I've been here before with Jirandiel. There is a dismantled trap in the corner over there, but the weirdest part are those footprints. Someone walked down this way, then carefully walked backwards in his own footprints, very strange. I think someone wanted us to go this way, but someone else beat us to it, and with the trap dismantled over there it should be safe. This part anyway. I have no clue about the water, magic is not something I'm intimately familiar with, and I can't think of any other way (let alone a reason) to get this water here without magic..
Unless someone has any idea what this water is doing here, let's continue, follow those other people, and see if we find ourselves at the other end of the ceiling-trap. If we're lucky they dismantled the traps ahead, which should save us considerable time, and might allow us to catch up."
