A mage of your kingdom, at the behest of the king, has created a knight that consists entirely of iron armor, with no man inside.

You've been a sorcerer's apprentice, but you've never met this creature. But one day, a mage commissioned you to wash the Iron Knight's armor, which you reluctantly had to do. You entered the room where the knight stood, and after soaking a cloth with water, you began to dust off his armor, starting with his hand.

"Here's a piece of iron." You muttered in displeasure, and at that moment his hand moved slightly. You looked up and saw his eyes staring right at you.

"I'm not a piece of iron," he said slowly, which made you very frightened. You didn't expect it to be able to talk.
