While Duke (Blacksmith) obviously went towards the path of being a smith, Luke just wanted to find a job. His criteria was nonexistent. Just finding a job would suffice. When asking around, Luke found out that the charm factory job was actually the easiest to get into. There were no requirements on the age, height, or ability. They would accept anyone and everyone.
After learning of this, and the location, Luke went straight to the factory. Without even checking his age, they let him join. After that day, he would be bringing as many materials from one place to another. That was his job.
AT 12 A.M., Duke and Luke met at the bench. Luke told Duke of his adventure and that he would need to carry materials. Duke told Luke of his choice to be a Blacksmith, saying "This is what I am meant to be. Just call me Blacksmith form now on."
