Fermat, Desiring Humanity

Lore
There was a childless armorsmith who was visited by a traveling mage. In exchange for shelter, he had been given plates of enchanted iron. By shaping it into a creature, it would spring to life, be it a bird, a fish, or a human. His desire for a son was so strong that he shaped it into a boy and named him Fermat. He lavished his artificial offspring with boundless affection that Fermat returned in kind. However, it was not until much later that the metallic shell realized the obvious. "I'm not a human?"
