My Chimer, Nylaathria.
Long story short. She's a priestess of the tribunal temple in Raven Rock. She has a stronger connection with Azura out of the three Daedric Princes. Azura see's her pure heart and strong loyalty that she uplifts her curse returning her to her original Chimer appearance.
"Goddess of Dusk and Dawn, though I may not serve you as a temple priestess of the tribunals anymore, my loyalty and gratitude will always remain. My duties as a worshiper always carries on even though you do not provide me with anymore visions. I'm still a humble servant among you, my goddess."
