Pinchy:
Well there isn't anywhere to put them. You can barracade the door but there isn't much to barracade it with. There are seven concentric circles, all overlapping, and it isn't hard to draw them, but that is all there is. It looks like someone had scrapped and area searched the wall all across the circles, looking for something on the doors, but there are no other marks. You keep knocking out the Dwarves and studying things and eventually, they all suddenly vanish in a blue ripple of light that becomes a blue flame in wall scones all around the room. The room is now lit. You are alone. You feel the moon changing, and then, you remember nothing....
