She held up a small crystal phial: it glittered as she moved it and rays of white light sprang from her hand. 'In this phial,' she said,' is caught the light of Earendil's star, set amid the waters of my fountain. It will shine still brighter when night is about you. May it be a light to you in dark places, when all other lights go out. Frodo took the phial, and for a moment as it shone between them, he saw her again standing like a queen, great and beautiful.
