Human: Produce a detailed written description of a depressing scene inside a keep with ironwood doors and an oak door. Assistant: 
The cold stone walls of this hall offer little comfort to the doomed souls that make the journey from the west entrance to the east entrance -- from their old lives to their new. Guards on the roof above watch the passage through a pair of iron grates, controlling the massive portcullis that can be lowered to seal the hall from the entrances. A reinforced oak door and a pair of large ironwood doors are set into the south wall.
