You approach the mansion and the door swings open by itself. I suppose that means it's proooobably ok to check out the premises. The inside is surprisingly well-decorated, in a fancy-Victorian-plywood-furniture kind of way, giving it a vibe that can be best described as crafty, “on-the-go Dracula." Or maybe “flatpack-Nosferatu." Oh, also there's no one here. In fact, you're kinda worried about what happened to the campers… But you need a DJ. You will not be deterred. In the center there's a staircase. One flight leads up into the cockloft, the other down to the tumulus.
