A huge chunk of rock falls from the ceiling as you dash for the exit, pulping the devil's corpse. There is a rumbling overhead that swells in volume, louder and louder, and just as you reach the iron door, part of the ceiling collapses, filling in the sparkling pool with a mound of broken boulders.
A large chunk of the ceiling falls above one of the vortexes and is sucked in. An instant later it is spit out of one of the others and ricochets around the room, destroying one of the rickety bridges. Lilli ducks through the door just before it smashes into the doorframe and shatters.
The door opens onto a wide tunnel that slopes downward. At the top of the slope, a train of 3 linked mine carts sit on top of a set of tracks that disappear off into the distance. The rearmost cart is filled to the brim with chunks of silver ore.
The ground rumbles again, and the tracks buck. A wedge of wood is dislodged from beneath one of the cart wheels and goes bouncing away down the tunnel. The carts jerk forward a few inches before they're stopped by the one remaining chock.
