Elena

Biography
Elena grew up as a clumsy, tomboyish girl, who enjoyed horseback riding - this was a result of her being possessed. Sometime after her twentieth birthday, she made the journey to Camelot for an arranged marriage to Arthur Pendragon. Though they bonded over a horse ride through the forest, neither of them had any feelings for the other. Arthur in particular found her manners nature slightly irritating and unattractive. Moreover Arthur was already in love with Guinevere and wished to avoid the arranged marriage for the sake of their love also. Meanwhile Elena felt she could not love Arthur because he did not understand her.

Eventually Merlin found out that Elena was a changeling, and part of a plot to put a sidhe on the throne of Camelot. The sidhe possessing her would take her over completely upon her marriage to Arthur. However, Merlin and Gaius managed to create a potion to force the sidhe out of her, and while Merlin held off and eventually killed Grunhilda, Gaius had trouble getting Elena to drink the potion, then Merlin burst in, tipped back Elena's head and poured the mixture down her throat which expelled the sidhe. The sidhe was then killed by Merlin. Being released from the Sidhe cured Elena of her clumsiness.

During the wedding, she and Arthur confessed that they were only marrying for duty, and neither had feelings for the other, and so called off the wedding. Arthur later said he noticed something different about her as she came down the castle steps without falling. As she was leaving, Elena told Arthur she hoped they both found the love they deserved, and if he wanted to be beaten in a horse race, he knew where to find her.
