I'm going to go slightly off-topic here and say that Melian was pretty powerful, not the most powerful, but fairly powerful. She controlled the borders of Doriath with the Girdle of Melian and kept the forces of Morgoth at bay, while still keeping Doriath looking like an elf-haven. Pretty good house keeping skills, I'd say. She also influenced Elu Thingol and seemed kind of like a person (elf) who wouldn't allow anyone's opinions to influence him. She's kind of a "pillow-talk" elf which I would say is a pretty powerful thing and I'd say that most of the ladies in here would agree. She's like the ultimate house wife! I bet the boys from Queer Eye are jealous.
