Fan Casting Ragnar Sturlusson in Northern Lights

Is a bear in armor that wants to be like a human. After usurping Iorek Byrnison and abandoning his former name Iofur Raknison, adopting Ragnar as king of the armored bears, he orders his subjects to build a palace of stone and wear ornaments of gold and silver, which were traditionally despised. He had dealings with the Magisterium and Mrs. Coulter, allowing them access to his kingdom in exchange for the ability to be baptized as Christians.
