After walking through what seemed to be a forest, Nick reached Albert's house.
Nick had seen a couple of houses on his way to Albert's house.
All the houses he had seen were made out of wood or mossy stone.
Only when Nick saw Albert's house did he realize that he hadn't seen a single piece of metal until now.
Albert's house, compared to all the other houses, was made of black metal.
It was the same kind of metal that the entrance to the upper layer was made out of.
Albert's house was the only thing made of metal that Nick had seen in the upper layer.
It was strange.
In the Dregs and in the Outer City, everyone was surrounded by nothing but metal.
The ground was metal.
The houses were metal.
Everything was metal.
But here, nothing was made of metal.
