Looking at walls you realize that room you are kept is round and lined with some sort of white, soft material. There are no doors whatsoever, only calming whisper of machinery somwhere deep below. Five or six meters above you see a small... window?
You wake up from your cold slumber, whole body aching. Eerie light showers your body in nice, warm feeling, but it passes soon. With eyes open you stand up, all muscles still frozen, but ready to take action.
