Somewhere hidden in Nightmare's Valt is a secret document made by Prison officials stating the real reason for the main cell being so mentally challenging but yet so easy to access it reads. The reason the cell is mentally attacking it the thought of being so close to getting out mixed with the lack of sleep due to the bed being hidden behind a wall messes with your mind especially when mixed with solitude. What we didn't plan for was the prisoners to lose thare minds fully we did expect was some small mental losses so to counter this we made a plan to transfer the prisoners to an mental institution one or two weeks before the end of their sentence unfortunately due to a unforseen war and the imprisonment of our highest official placed at that prison we had to postpone project Arkham and it has not been planed to start yet.
