Well I put in my two cents about this topic. I think she is deservedly damned, I want nothing more than to see the back of her. Get rid of her, leave her a loose end. Have Rayek come back without her in his head and just saying "She's gone folks.".
I really don't care WHAT happens to her as long as I don't have to read about her anymore. She did her thing, she fulfilled her palce in the storyline (as in, just 'cause they're pretty doesn't mean that all elves are good people who deserve good things to happen to them). Let her rest and give us a new villian who we can all love to hate. Because in the end that's what great villians are...characters we absolutely love to hate.
