The Caller was in a circular room with three lecterns, one in the middle of the room, and two in side rooms to the left and right. The lecterns in the side rooms each displayed one of the missing books, but there was nothing on the lectern in the circular room, although that would seem THE logical place for it to be. We've searched all the nearby rooms as well, without luck. I'd reload and try again, but I'm not sure we could ever win the battle with The Caller again. We must have died a fiery death 15 or 16 times over a couple of real-time days.
Does anyone have any suggestions?
