Tried a more fairy-tale approach for this one! Been trying different writing styles lately. Feedback is welcomed!
A king once told a local blacksmith to build him the strongest shackles in the world so he could capture a dragon and take its gold. In return, the blacksmith would receive a large portion of the wealth.
Immediately after the king’s proposition, the blacksmith ordered his son to travel the world and send him the strongest stones he finds. Whenever the blacksmith received a stone, he molded it into a shackle, and tested the strength of it on himself, as he was a strong man. After several years, the blacksmith had finally found the strongest metal, but he could not tell the king because he had locked himself at home.
