Now in his heart Melkor most hated the Eldar, both because they were fair and joyful and because in them he saw the reason for the arising of the Valar and his own downfall. Therefore all the more did he feign love for them and seek their friendship, and he offered them the service of his lore and labour in any great deed that they would do. The Vanyar indeed held him in suspicion, for they dwelt in the light of the Trees and were content; and to the Teleri he gave small heed, thinking them of little worth, tools too weak for his designs. But the Noldor took delight in the hidden knowledge that he could reveal to them; and some harkened to words that would have been better for them never to have heard. Melkor indeed declared afterward that Fëanor had learned much art from him in secret and had been instructed by him in the greatest of all his works; but he lied in his lust and his envy, for none of the Eldalië ever hated Melkor more than Fëanor, son of Finwë, who first named him Morgoth; and snared though he was in webs of Melkor’s malice against the Valar he held no converse with him and took no counsel from him. For Fëanor was driven by the fire of his own heart only; working ever swiftly and alone; and he asked the aid and sought the counsel of none that dwelt in Aman, great or small, save only for a little while of Nerdanel the wise, his wife.
