THE VALAR: Nienna by Tania Weil. Lady of Mercy. She was the tutor of Olórin (Gandalf), and weeps constantly. But she does not weep for herself; and those who hearken to her learn pity, and endurance in hope. Her tears are those of healing and pity, not of sadness, and often have potency; for example, she watered the Two Trees with her tears, and later washed the filth of Ungoliant away from them once they were destroyed. She has no spouse.
