Bears! The terms of combat are these. If Iofar Raknoson kills me, then he will be king for ever, safe from challenge or dispute, If I kill Iofar 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 in to the sea. Iron is bear-metal. Gold is not. Iofar Raknison has polluted Svalbard. I have come to cleanse it. Iofar Raknison, I challenge you.
