The cells

The cells where the prisoners would stay with there creature would usually have inside of them: a purposely flickering light that lets of a small buzz, A steel door made up with around 67 layers, A damp carpet, A small wooden desk, 2 beds with a moist mattress and finally a steel toilet that couldn't flush so the smell of piss and shit would stay around for days on end until the janitor would decide to go too your room and clean it up.
