You wake up slowly, unable to remember who or where you are. You open your eyes, and find yourself in a small stone room, with no windows and no visible doors. On one side of the room is a speaker. On the other, nine huge stone blocks stick out from the wall in the shape of a square. A robotic female voice emits from the speaker.
