Quotes from The Silmarillion
"Sauron was become now a sorcerer of dreadful power, master of shadows and of phantoms, foul in wisdom, cruel in strength, misshaping what he touched, twisting what he ruled, lord of werewolves; his dominion was torment. He took Minas Tirith by assault, for a dark cloud of fear fell upon those that defended it; and Orodreth was driven out, and fled to Nargothrond."

"Morgoth held hurled aloft Grond, Hammer of the Underworld, and swung it down like a bolt of thunder. But Fingolfin sprang aside, and Grond rent a mighty pit in the earth, whence smoke and fire darted. Many times Morgoth essayed to smite him, and each time Fingolfin leaped away, as a lightning shoots from under dark cloud; and he wounded Morgoth with seven wounds, and seven times Morgoth gave a cry of anguish, whereat the hosts of Angband fell upon their faces in dismay, and the cries echoed in the Northlands."

"Now news came to Hithlum that Dorthonion was lost and the sons of Finarfin overthrown, and that the sons of Fëanor were driven from their lands. Then Fingolfin beheld… the utter ruin of the Noldor, and the defeat beyond redress of all their houses; and filled with wrath and despair he mounted upon Rochallor his great horse and rode forth alone, and none might restrain him. He passed over Dor-nu-Fauglith like a wind amid the dust, and all that beheld his onset fled in amaze, thinking that Oromë himself was come: for a great madness of rage was upon him, so that his eyes shone like the eyes of the Valar. Thus he came alone to Angband’s gates, and he sounded his horn, and smote once more upon the brazen doors, and challenged Morgoth to come forth to single combat. And Morgoth came."

"Many are the strange chances of the world,’ said Mithrandir, ‘and help oft shall come from the hands of the weak when the Wise falter."
