Hall of Mirrors
This a twisting, windowless hallway lined with lights and mirror mosaics. Each mirror represents someone who died. Each light is a village that was destroyed to nothingness.
At first the hallway is a dazzling, shimmering sight. But as you make one turn after another, the hallway seems to never end. The body count piles higher and higher -- and higher.
You are no longer dazzled. You feel like the weight of the world is crushing you.
