Flowing Songs of Healing by Anérea  

Weaving songs of healing

After singing the two trees into being, Yavanna gave thought to the now-dark lands beyond the Pelori, where green things had fallen sick and rotted, rivers become choked slime, fens made rank and poisonous. She mourned for all that had once flourished. Thus she called upon Ulmo to travel thence with her to heal the hurts done to Middle-earth. Flowing her song through his music into the waters nourishing all living things, gradually, in the twilight under the stars, the rivers flowed clear once again, olvar pulled nourishing sap up their stems and trunks, and the kelvar thrived as before.
