A Plunge into Darkness

Night falls on a group of friends roleplaying together, and as eyelids become heavy, bedtime seems to be the only option. But Sven has another idea. He wants to show his friends an old castle that hasn't been inhabited for centuries. Good or bad idea? Despite a bit of reluctance from some, the group enters the castle and decides to give it a short visit. What started as a bit of fun is about to become a life-changing event for them. But the real question is: can they make it out of the castle alive?
