§ Of Fëanor and the Unchaining of Melkor The Silmarillion

The wedding of his father was not pleasing to Fëanor; and he had no great love for Indis, nor for Fingolfin and Finarfin, her sons. He lived apart from them, exploring the land of Aman, or busying himself with the knowledge and the crafts in which he delighted. In those unhappy things which later came to pass, and in which Fëanor was the leader, many saw the effect of this breach within the house of Finwë, judging that if Finwë had endured his loss and been content with the fathering of his mighty son, the courses of Fëanor would have been otherwise, and great evil might have been prevented; for the sorrow and the strife in the house of Finwë is graven in the memory of the Noldorin Elves. But the children of Indis were great and glorious, and their children also; and if they had not lived the history of the Eldar would have been diminished.
