"Precisely. The names are pulled out of a hat. The participants have only 
a few hours' warning. Here, the ritual is done with a cliff and a rope, because 
there happened to be a cliff in the vicinity. In other R.D.R. nodes, the 
mechanism might be different. For example, person A might go into a room, take 
a pistol out of a box, load it with live ammunition, put it back in the box, 
and then leave the room for ten minutes. During that time, person B is supposed 
to enter the room and replace the live ammunition with a dummy clip having the 
same weight. Then person A comes back into the room, puts the gun to his head, 
and pulls the trigger."
