Role in the Series[]
He and his daughter visit Camelot as part of peace talks with the rulers of the Five Kingdoms. Arthur and Vivian are enchanted by Trickler in a plot by King Alined, to fall in love with each other. When Olaf finds out about their relationship, he becomes furious and challenges the prince to a duel to the death and demands recompense. Arthur eventually wins, but spares Olaf, saying that this isn't the way to make peace. Olaf then forgives Arthur and leaves, along with his daughter, to return back to his kingdom (Sweet Dreams).
