Lady of Light
"And for you, Frodo Baggins, I give you the light of Earendil our most beloved star. May it be a light to you in dark places when all other lights go out."
Here's Galadriel, Lady of Light, the Lady of Lórien who gave the Fellowship of the Ring important gifts. She could also be used for a princess, if you don't mind the pointy ears.

"Galadriel was a Noldo, one of the Calaquendi. She was one of the bearers of the Three Rings, of Nenya, and with it kept her realm of Lothlórien free of stain." - Tolkien Gateway
