You reach the end of the passageway and grab the doorknob. The door is unlocked, and you make your way through to the other side. As you pass through, the door closes and locks behind you. To your left is a wooden door. Another dark corridor extends out to your right. This new door may lock behind you, too. On the other hand, you may come across something unpleasant at the end of the corridor. You have to do something.
