After several attempts to lift the heavy portcullis, you ask the others to help. All three of you grasp the bottom and heave. The portcullis slowly rises over your heads and locks in place with a click. You all step through quickly. You hear the chains of the portcullis rattle loudly, and turn around just in time to see the heavy gate slam back to the ground. As you inspect it, you see that one of its chains snapped. You would have to replace this chain before operating the gate again. Go to page 115.
