It was abandoned by the raiders and slaves when trogs started moving into the area, but it's still used to get to the steelyard, so the slaves were made to construct a barrier so that other slaves could get to the steelyard safely.
While it serves as a vestibule between the Mill and the steelyard, the abandoned area has otherwise been deserted by both slavers and slaves alike in light of the trog infestation. There is a locker near the entrance to the steelyard - it can be used to store gear and lighten up for ingot runs as its contents are indefinite and it does not reset. In a mine cart, there are three steel ingots - these are inaccessible until returning from gathering the first ten in the quest Unsafe Working Conditions, after which a trog tears a hole in the fence.
