As you, Brother Andrew, pass beneath the fourth tower, and just as you notice the out-stretched arm of the first stone cross reaching out from behind a boulder, a stone rolls down the from the base of the tower to land at your feet. Another rolls down, and another. Then a low rumble you've only just noticed turns into a thunderous roar, and the entire fourth tower appears about to crash down upon your head...
The path leads east past the fourth tower or west back to the first three towers. To the south is the abyss and to the north is the LANDSLIDE!!
