Arthur
Arthur, originally named Gwydion, is Igraine and Uther's son. Taking after Uther's fair complexion and good looks, Arthur is often sick or hurt as a child. When Viviane finds this out, she believes someone is sabotaging Arthur's ascension to the throne as High King. Arthur is therefore sent to live as King Ectorius' foster son until he is old enough and strong enough to go through trials and kingmaking rituals necessary in order for him to be king. From a young age, he is conscientious of what it takes to be a good soldier. It is not until he receives Excalibur that he truly begins to lead a charmed life. Arthur is not a remarkable fighter; it is only because he carries Excalibur that he never receives, an injury bad enough to kill him.
As part of his kingmaking, Arthur receives Excalibur, the magical scabbard and the Holy Regalia of Avalon, as he swears to defend Avalon. It is later, when he breaks his oath to Avalon that Viviane, and then Morgaine, work to take these holy items back. At his wife's urging, Arthur rejects the ways of Avalon and becomes a Christian. Arthur gives in to Gwenhwyfar's every whim, which goes against the current convention where men tell their women what to do. Arthur is easily ruled. It is this trait that Morgaine fails to take advantage of when it comes to honoring his oath to Avalon. During a ritual at his kingmaking, Arthur and Morgaine sleep together, not knowing who the other is. Morgaine has a son from this union, who it is prophesied to challenge Arthur for the throne.
