Then Yavanna arose and stood upon Ezellohar, the Green Mound, but it was bare now and black; and she laid her hands upon the Trees, but they were dead and dark, and each branch that she touched broke and fell lifeless at her feet.
Yavanna spoke before the Valar, saying: "The Light of the Trees has passed away, and lives now only in the Silmarils of Feanor."

...And Nienna arose and went up onto Ezellohar, and cast back her grey hood, and with her tears washed away the defilements of Ungoliant; and she sang in mourning for the bitterness of the world and the Marring of Arda.
