A simple Metal Lock
Eisen looked at the glowing, hot metal in front of him, quickly picking it up. The massive hunk of metal was enough to make dozens of armours for people out of, but what Eisen was using it for in this case was a lock. The cost behind it all was a massive reason why, in the giant country, the most massive cities were carved from mountains. It was incredibly hard to justify using so much material on housing for people that were able to adjust their size basically however they wanted, but like that, they could use the materials that were harvested from the carving-out of what was basically a sort of massive quarry, to further construct other buildings. But even so, seeing things that weren't made of stone or wood was incredibly rare.
