An empty stone causeway. Any who travel through here do so quietly and quickly. Free dead forced to stay in this room become nervous and complain about the feeling of being watched. The north wall is covered in a complex array of small copper pins and a low hum makes communication and spellcasting difficult. The living in this room will have the feeling of being safe and a little bored. The north wall can be disabled in three hours with proper tools and reveals a complex array of technologies. A wizard can research for one week to determine that this apparatus casts calm emotions on the living but causes paranoid delusions in the free dead.
