Hmm... I suppose that depends what role you would like for her to have in the story. You would not truly make her the villain forever, correct? That would be considered quite blasphemous.

[Considering she's based on Lady Kee'ra and all...]

Perhaps once she is defeated by Dhurke [The character, since equating 'Father' to that... interesting depiction... is a little insulting,] she could be a sidekick or a partner in delivering justice to Khura'in, so you should choose a name accordingly. I think that would be an exciting plot twist.
