At first glance the room appears to be incredibly empty, with the exception of the table in the center of the space and the mirror. Upon closer examination, however, you find that the walls appear to hold some secrets. Strange indents in the otherwise-smooth surface indicate there are panels that can possibly pull away from the walls and reveal what you think may be hidden beneath.
The sudden dimming and flickering of the lights seizes your attention, and you watch the hanging fixture as it buzzes into darkness for a moment before retaining its glow. You know you may soon be in the dark.
