Produce a detailed written description of a depressing scene inside a keep with ironwood doors and an oak door.

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.
