"It came to pass that Nargothrond was full-wrought (and yet Turgon still dwelt in the hills of Vinyamar), and the sons of Finarfin were gathered there to a feast; and Galadriel came from Doriath and dwelt a while in Nargothrond. Now King Finrod Felagund had no wife, and Galadriel asked him why this should be; but foresight came upon Felagund as she spoke, and he said: ‘An oath I too shall swear, and must be free to fulfill it, and go into darkness. Nor shall anything of my realm endure that a son should inherit."
