If Iofur Raknison kills me, then he will be king forever, safe from challenge or dispute. If I kill Iofur Raknison, I shall be your king. My first order to you all will be to tear down that palace, that perfumed house of mockery and tinsel, and hurl the gold and marble into the sea. Iron is bear-metal. Gold is not. Iofur Raknison has polluted Svalbard. I have come to cleanse it. Iofur Raknison, I challenge you."
