Odin
King Odin (portrayed by Fintan McKeown) is the ruler of a kingdom neighboring Camelot. Arthur killed his son in single combat; he did not have a quarrel with the boy, but the other prince would not back down from the challenge. In retaliation, Odin sent a professional assassin, Myror to Camelot to attempt to kill Arthur in the episode The Once and Future Queen. Myror took the place of Arthur's opponent in the joust, and Merlin had to use his magic to loosen the strap on his horse's saddle in order to save Arthur. Uther wanted to make war against him, but Arthur talked him out of it, saying Odin had been motivated by grief. In The Wicked Day, Odin sends The Gleeman to assassinate Arthur. He fails in this task, but succeeds in fatally injuring and later killing Uther.
