All of Golgotha’s traps are basically the same. All of them derive their killing power from the pressure of the water communicated down to this level from the bottom of Lake Yamamoto. In any number of places in the complex, false walls have been constructed, designed to be pierced by greedy thieves, or to collapse of their own accord when thieves dig out the sand that holds them up. Then the water will rush in with explosive force and probably crush them before they have a chance to drown.
