You and 20 other people wake up in an empty room. The people look around in confusion, as a voice calls out over a loudspeaker.

“Hello, humans. One of you will have to be sacrificed each day to ensure the safety of the others. If you do not, two of you will be chosen at random. Food and water will be provided to you. Good luck.”

Everyone erupts into an uproar of shouting. But they slowly calm down once they hear the sound of sniffling. They turn to you, a mere child, huddled in a corner.
