you look around and see that there is a switch to turn the machine on and off, and at the moment you spot it you hear a war cry echoing through the caverns...

suddenly the whole room gets so cold that you can't move, a leaf floating down to the ground falls instantly when you hit it. You see the tip of a sword sticking out from the corridor behind you.
Then you look at the ice frozen on the wall and see the reflection of 10 or so orcs 5 with swords and 5 with bows.
