At the end of the hall lies a large door. The creature approaches it, sensing a great pressure from within. It tries to force the door open, but finds itself unable. It turns from the door, losing interest in it.
Behind that door is a great white room, with a checkerboard floor. At its center lies a lone girl. She is held in place by great and black magical chains. The weight of them, aswell as the spell they hold, keeps her in a state of dormancy. As long as power runs through the facility, she will not awake.
