The Dark Knight

You were a witch and threatened to destroy every living thing in the village. They gave you riches and food every day, but you still destroyed the village. A brave knight survived. He wanted revenge and came to you every time with a sword in his hands, but you killed him. Each time he was resurrected and became stronger and stronger. You killed him again, and he returned again after six months. He became dark and large, with crushing power. You realized that you couldn't kill him, so you hid from him. Four years later, the brave knight found you, with a crushing sword in his hands. I've come back for you, impudent witch! You cannot escape justice!
