Description of Elrond
"The master of the house was an elf-friend - one of those people whose fathers came into the strange stories before the beginning of History, the wars of the evil goblins and the elves and the first men in the North. In those days of our tale there were still some people who had both elves and heroes of the North for ancestors, and Elrond the master of the house was their chief." (Chapter 3)
Character and appearance
"He was as noble and as fair in face as an elf-lord, as strong as a warrior, as wise as a wizard, as venerable as a king of dwarves, and as kind as summer." (Chapter 3)
Elrond's Words and Deeds
Elrond identifies the swords from the troll-hoard:
"Elrond knew all about runes of every kind. That day he looked at the swords they had brought from the trolls' lair, and he said: 'These are not troll-make. They are old swords, very old swords of the High Elves of the West, my kin. They were made in Gondolin for the Goblin-wars. They must have come from a dragon's hoard or goblin plunder, for dragons and goblins destroyed that city many ages ago. This, Thorin, the runes name Orcrist, the Goblin-cleaver in the ancient tongue of Gondolin; it was a famous blade. This, Gandalf, was Glamdring, Foe-hammer that the king of Gondolin once wore. Keep them well!'" (Chapter 3)
"'Whence did the trolls get them, I wonder?' said Thorin, looking at his sword with new interest. 'I could not say,' said Elrond, 'but one may guess that your trolls had plundered other plunderers, or come on the remnants of old robberies in some hole in the mountains of old. I have heard that there are still forgotten treasures to be found in the deserted caverns of the mines of Moria, since the dwarf and goblin war.'" (Chapter 3)
Elrond reads Thorin's map
"He took it and gazed long at it, and he shook his head; for if he did not altogether approve of dwarves and their love of gold, he hated dragons and their cruel wickedness, and he grieved to remember the ruin of the town of Dale and its merry bells, and the burned banks of the bright River Running. The moon was shining in a broad silver crescent. He held up the map and the white light shone through it. 'What is this?' he said. 'There are moon-letters here, beside the plain runes which say "five feet high the door and three may walk abreast".'" (Chapter 3)
"'Moon-letters are rune-letters, but you cannot see them,' said Elrond, 'not when you look straight at them. They can only be seen when the moon shines behind them, and what is more, with the more cunning sort it must be a moon of the same shape and season as the day when they were written. The dwarves invented them and wrote them with silver pens... These must have been written on a midsummer's eve in a crescent moon, a long while ago.'" (Chapter 3)
Elrond and Gandalf speak of the Necromancer
"It was in this way that [Bilbo] learned where Gandalf had been to; for he overheard the words of the wizard to Elrond. It appeared that Gandalf had been to a great council of the white wizards, masters of lore and good magic; and that they had at last driven the Necromancer from his dark hold in the south of Mirkwood.
"'Ere long now,' Gandalf was saying, 'the Forest will grow somewhat more wholesome. The North will be freed from that horror for many long years, I hope. Yet I wish he were banished from the world!'
"'It would be well indeed,' said Elrond, 'but I fear that will not come about in this age of the world, or for many after.'" (Chapter 19)
