Here is a place that is full of hundreds of people, all identically dressed in dark green tracksuits. Well -- identically dressed, but for the sigils on their chests. Their faces are drawn and tense. They are focused on ominous figures at the front of the room on a raised stage.
The figures in front wear red hooded bodysuits with black masks completely covering their faces. Six of the seven have a large white triangle inscribed on their foreheads. The one in front has a square.
The square intones, "It is time for the first game. Form an orderly line."
The green tracksuit people shuffle into place, some whispering or quietly crying. The line begins to move forward, slowly at first and then more briskly.
