The form you see in Waypoint Ruins is just a projection, as her true self is held prisoner in a the Witchbane Ruins. If the Tarnish chooses to help her, she will ask them to put her Primal Glintstone into a new body. The Tarnish can choose to continue to help, or fight her, at the end of her questline. In either case, she ends up with a terrible fate. Should the player help her, she is transformed, along with her fellow conspirators, into a school of graven mages, where she is barely able to speak.
