Vivian

Not a true villain, but certainly no hero either, Lady Vivian is the beautiful, but spoilt daughter of King Olaf, whom Arthur temporarily falls in love with, though his feelings were caused by an enchantment and were not genuine.

Biography
Not much is known about Lady Vivian's life before or after "Sweet Dreams" though she claims her father once attacked one of her previous lovers with a knife.

Lady Vivan is the daughter of King Olaf. She appears in "Sweet Dreams," accompanying her father King Olaf to the peace talks at Camelot. She is rude and dismissive towards Arthur and Gwen though she greatly enjoys Trickler's show. She is central to King Alined's plan to disrupt the peace talks, bringing about war and making him rich. Alined orders Trickler to magically cause Arthur to fall in love with Vivian, hoping to provoke the overprotective Olaf and end the peace talks. Arthur kept harrassing her with thoughtful words and gifts leaving Gwen hurt and left out. When Vivian fails to return Arthur's affections voluntarily, Trickler performs a similar spell on her. Olaf soon discovers this affair and challenges Arthur to a duel to the death. She shows no sign of discomfort or worry for either of them, though this may be a result of the enchantment. With Merlin's help, Arthur is able to free himself from the spell by kissing his true love, Gwen. However, Vivian has not yet met her true love and is therefore still under the spell when she leaves Camelot.

Personality
Vivian was an attractive but vain girl and was not afraid to give her opinion which often made her seem rude. She initially showed no interest in Arthur and it might have remained that way if not for Trickler's magic. Vivian was rude to people of lower rank than herself, thinking that they owed her total obedience.
