You push off a rough blue blanket which has been placed over your body. Slowly you gaze around the room, consciousness just returning in the dim light of what appears to be an underground room. As your eyes re-connects with your brain, you make out a barred window fifteen feet up on one wall. There's an opening, perhaps six feet square, high up on the ceiling. Besides that there's nothing else in the room.
Except for the half a dozen lumps under blue blankets scattered about the dusty floor. The nearest lump to you appears to be moving slowly; the centre of the body moving up and down. On closer inspection, you can see that each blanket is covering a slumbering body.
One of the lumps stirs, and an arm, then a head appears. The head looks round until it sees your face. The head belongs to a mid teenage boy, but is bloody and bruised and the hair is shaved. It seems strangely familiar.
