What could possibly drown out the din of the sea? Even the thousand waterfalls of Imladris seem helpless against it.
I have heard the ocean's roar often enough. After my brother told me he chose a mortal life, and sailed Westward, I stood on the beach watching Father cross the sky. Later years brought me back to Mithlond, when the sea carried away my wife also.
So I know the roar in my ears for what it is. I am weary of Arda's cares. The Sea calls me, and for all Vilya's power over water, I cannot master this urge.
