there have come to the ears of ulmo whispers of your dwelling and your hill of vigilance against the evil of melko , and he is glad : but his heart is wroth and the hearts of the valar are angered who sit in the mountains of valinor and look upon the world from the peak of taniquetil , seeing the sorrow of the thraldom of the noldoli and the wanderings of men ; for melko ringeth them in the land of shadows beyond hills of iron .
